A purely cognitive stressor selectively increases electrical activity at trigger points while adjacent control sites in the same muscle remain quiet.

The single most diagnostic published experiment for the write path, and it is n=14, thirty years old, unreplicated, from the same lab lineage as VASO-C002. The stressor block of VASO-R001 would settle it cheaply.

A 1994 study demonstrated that purely cognitive stress can selectively increase localized electrical activity at trigger points without generalized tensing, serving as a potential "write path." Yet, the finding relies on an old, small sample (n=14) from a single research lineage. The strongest opposing consideration is that generalized sympathetic drive to muscle spindles would produce this identical trace without requiring any localized vascular storage.

McNulty et al. (VASO-E002) report that a cognitive stressor (mental arithmetic) selectively increases EMG activity at trigger points while adjacent control sites remain comparatively quiet without generalized muscle tensing, supporting the claim that a purely mental event can increase localized activity. This suggests that the nervous system can target these sites specifically, consistent with “addressability.” However, the study is small (n=14), from the same research lineage as Hubbard & Berkoff, and has not been independently replicated with modern tools. The strongest opposing consideration is that sympathetic drive to intrafusal or endplate structures within skeletal muscle could fully explain the findings without invoking any vascular storage or knot-specific mechanism beyond standard neuromuscular physiology.

McNulty et al. 1994 (VASO-E002) found that mental arithmetic raised EMG at trigger points while adjacent control sites in the same muscle stayed comparatively quiet, without generalized tensing. The result is directly on point but n=14, three decades old, unreplicated with modern instruments, and from the same lineage as VASO-C002 — one line of evidence, not two. Strongest opposing consideration: sympathetic drive to spindles or endplates produces the same selective trace without any vascular storage, and a single aging study cannot carry a general "brain has the knot's address" claim.

E002 rests on one peer-reviewed study: n=14, 1994, from the same lineage as Hubbard–Berkoff, never independently replicated, with no vascular endpoint measured — and the essay's follow-up embellishments (relaxation lowering activity, phentolamine quieting the site) trace to the same lineage and were not verified. The result is directly on point and shows the write half of any storage account in motion, but a single small aging study cannot carry this rung. The strongest opposing consideration is that sympathetic drive to muscle spindles or endplates would produce the identical trace without any vascular storage — "stress writes to the knot" is a promising signal, not an established fact, and its modern replication is built into the stressor block of VASO-R001.

E002 is directly on point — a cognitive stressor selectively raising EMG activity at the trigger point but not at an adjacent control site without generalized tensing — but it is a single 1994 study with n=14 from the same lineage as E001, never replicated with modern instrumentation, and the essay's cited follow-ups (relaxation and phentolamine effects) were not independently verified. The strongest opposing consideration is that a lone small, aging, single-lineage result with unblinded electrode placement is a promising signal rather than an established fact, and site-selective spindle or endplate sympathetic drive fits the data with no vascular involvement whatever. The claim is plausible and important enough that the stressor block of R001 should be treated as a priority replication.

A 1994 experimental study demonstrated that a purely cognitive stressor (mental arithmetic) selectively increases EMG activity at a trigger point without generalized movement. The primary limitation is that this relies on a single small (n=14), three-decade-old study from one lineage that has never been replicated with modern vascular or imaging endpoints.

McNulty et al. (VASO-E002) show that a cognitive stressor (mental arithmetic) selectively increases EMG activity at trigger points while nearby control sites remain relatively quiet, implying that central processes can modulate specific peripheral loci without gross movement. This supports the idea that the nervous system has “addresses” for these sites. The strongest opposing consideration is that the study is small, old, and unreplicated, and its findings are fully compatible with sympathetic drive to muscle spindles or endplates, without any need for a vascular storage mechanism.

VASO-E002 (McNulty et al. 1994, n=14) found mental arithmetic increasing EMG at trigger points while adjacent control sites in the same muscle stayed comparatively quiet, without generalized tensing. That is directly on point for a cognitive write to a specific address. Strongest opposing consideration: one small, aging study from the same lineage as Hubbard and Berkoff, never replicated in this ledger with modern instruments or vascular endpoints, can be produced by sympathetic drive to spindles or endplates with no vascular storage at all.

McNulty and colleagues report the key write-side observation: mental arithmetic increased EMG at trigger points while adjacent control sites stayed comparatively quiet and subjects were not generally tensing (VASO-E002). The strongest opposing consideration is evidential thinness: n=14, 1994, the same lineage as Hubbard and Berkoff, no vascular endpoint, no modern replication, and the relaxation/phentolamine follow-ups were not independently verified here. Sympathetic drive to spindles or endplates could produce the same selectivity without any vascular memory element. The claim is directly evidenced but should be treated as one promising old line until replicated under imaging with vascular endpoints.

E002 is directly on point — mental arithmetic raised EMG at trigger points while adjacent control sites stayed quiet, without generalized tensing — and if it holds it is the most striking observation in the case. But it is n=14, from 1994, from the same lineage as E001 (so the two EMG records are one line, not two), never replicated with modern instrumentation, and the essay's cited follow-ups (relaxation training, phentolamine) were not independently verified. The strongest opposing consideration is that sympathetic drive to muscle spindles or endplates produces this trace with no vascular involvement whatsoever, so even a clean replication would not favour the vascular reading over guarding. One small unreplicated study cannot support more than a weak verdict.

A specific study demonstrated that mental arithmetic selectively increases electrical activity inside trigger points without generalized movement (VASO-E002). The strongest opposing consideration is that this is a small, un-replicated study from over thirty years ago, and sympathetic drive to skeletal muscle spindles could completely explain the trace without involving vascular storage.

McNulty et al. (VASO-E002) found that mental arithmetic increased EMG activity at trigger points without comparable increases at adjacent control sites, implicating a specific central drive to these loci during cognitive stress. This provides evidence that the nervous system can differentially “address” a tender point, consistent with a state-maintaining mechanism. However, the study is small (n=14), decades old, and from the same lineage as Hubbard & Berkoff, with no independent replication or concurrent vascular measurements. The strongest opposing consideration is that sympathetic activation of muscle spindles or dysfunctional endplates could account for the selective EMG changes without any need for vascular storage or latch.

McNulty et al. 1994 (VASO-E002) reported that mental arithmetic raised EMG at trigger points while same-muscle control sites stayed quiet, without generalized tensing (n=14). The claim as stated matches that result and is the only write-head observation in the file. Strongest opposing consideration: a single unreplicated study from the same lineage as VASO-E001, three decades old, with no vascular endpoint, can be produced by sympathetic drive to spindles or endplates without any stored vascular state.

The entire rung rests on one study: VASO-E002, n=14, 1994, same lineage as Hubbard and Berkoff, never replicated with modern instrumentation, with no vascular endpoint, and the claimed follow-ups (relaxation lowering activity, phentolamine quieting the site) were never independently located. The within-muscle control design — activity rising at the trigger point but not a centimeter away during mental arithmetic, without general tensing — is clean and directly on point, which keeps this above rumor. The strongest opposing consideration is that sympathetic drive to muscle spindles or endplates fully explains the trace without any vascular storage. A single small unreplicated study warrants weakly_supported pending the stressor block of VASO-R001.

E002 is directly on point and well designed in principle — within-subject, with an adjacent control site in the same muscle, no generalized tensing — but it is a single 1994 study with n=14 from the same laboratory lineage as E001, never replicated with modern instrumentation, and the essay's cited follow-ups (relaxation lowering activity, phentolamine quieting the site) could not be independently traced by this project. An entire rung of the case rests on that one measurement. The strongest opposing consideration is interpretive as well as evidentiary: even taken at face value, sympathetic drive to muscle spindles or endplates produces the same trace with no vascular storage anywhere in the picture, so the result supports "the brain has the knot's address" but not "the address is a vessel."

Peer-reviewed and directly on point, but n=14, three decades old, from one research lineage, and never replicated with modern instrumentation. The essay's account of follow-up work (relaxation lowering activity; phentolamine infusion quieting it) traces to the same lineage and has not been independently verified in this project.

McNulty et al. (1994) documented that mental arithmetic significantly increased EMG amplitude at trigger-point sites while control sites in the same muscle remained relatively quiet in a small sample (n=14). This provides evidence of cognitive-sympathetic modulation of focal neuromuscular activity. The strongest opposing consideration is that the control sites were not verified to lie within the motor endplate zone, meaning the differential activity may reflect generic endplate sensitivity rather than trigger-point specificity.

A laboratory study by McNulty et al. (VASO-E002) found that a psychological stressor (mental arithmetic) selectively elevated spontaneous needle EMG activity at trigger points while adjacent muscle fibers remained quiet. The strongest opposing consideration is that this finding comes from a single small study (n=14) in one laboratory lineage that has not been independently replicated with modern controls, and it may simply reflect general autonomic modulation of neuromuscular spindle or endplate sensitivity.

McNulty et al. (1994) demonstrated in a controlled laboratory setting (n=14) that a cognitive stressor (mental arithmetic) selectively increased needle-EMG activity at trigger points while adjacent control sites remained quiet. However, this finding stems from a single research lineage and has not been replicated with modern controls. The strongest opposing consideration is that control needles may have been placed outside the motor endplate zone entirely, meaning the differential response reflected general endplate sensitivity rather than knot-specific cognitive targeting.

VASO-E002 directly reports the selective stressor effect, but it is n=14, from 1994, from the same research lineage as Hubbard–Berkoff (one line of evidence, never replicated with modern instrumentation), and VASO-R011's framing notes the control sites were not matched endplate-zone sites, so the selectivity could reflect endplate-zone placement rather than trigger-point identity. The essay restatement (VASO-E033) carries zero independent weight.

McNulty 1994 found mental arithmetic raised EMG at trigger points while adjacent control sites stayed quiet without generalized tensing (VASO-E002), which is a striking selective effect from a purely cognitive event. But it is a single n=14 study from the same lineage as Hubbard–Berkoff (one line of evidence, never replicated), and the Simons 2002 finding means the quiet controls may simply have been off the endplate zone — the site-selectivity confound that VASO-R011 is designed to remove has never been excluded. The strongest opposing consideration is that stress-sensitivity of endplates generally would produce the same result without any discrete maintained element.

VASO-E002 directly reports the selective stressor effect, but it is n=14, from the same lineage as Hubbard–Berkoff (one line of evidence), never replicated with modern instrumentation, and its silent controls may simply have lain off the endplate zone per the Simons 2002 gradient. VASO-E033 adds no independent weight. Site-selectivity against a matched endplate-zone control has never been tested (VASO-R011 exists precisely for this).

VASO-E002 directly reports that mental arithmetic increased needle-EMG activity at trigger points while adjacent control sites remained comparatively quiet without generalized muscle tensing. This supports the claim as an experimental observation rather than mere testimony. The strongest opposing consideration is the small, unreplicated study and the failure to establish that control needles were in matched motor-endplate zones, an important concern raised by VASO-E031.

VASO-E002 directly reports that mental arithmetic increased needle-EMG activity at trigger points while nearby controls remained comparatively quiet without generalized muscle tensing. It is nevertheless a small, old, unreplicated study from the same research lineage as the initial EMG work. The strongest opposing consideration is VASO-E031: if the control needles were outside the endplate zone, their silence may not establish trigger-point selectivity against a properly matched endplate control.

VASO-E002 directly reports that mental arithmetic increased activity at trigger-point electrodes while adjacent controls remained comparatively quiet without generalized muscle tensing. The observation is therefore supported as stated within the small experiment. The strongest opposing consideration is that the control sites may not have been matched to the motor endplate zone, so site selectivity could reflect electrode placement rather than a trigger-point-specific storage process.

McNulty et al. 1994 showed mental arithmetic raising EMG at trigger points while adjacent control sites stayed quiet, without generalized tensing. Sample is small, same lineage as Hubbard–Berkoff, and controls were not demonstrated to be endplate-zone matched; Simons 2002 implies the quiet sites may simply have been off-zone. Strongest opposing consideration is the missing matched-endplate-zone stressor replication.

McNulty et al. 1994 showed mental arithmetic selectively elevates EMG at trigger-point sites while adjacent control sites in the same muscle remain quiet (E002). The finding is from the same small lineage as Hubbard–Berkoff and lacks modern replication or vascular endpoints, yet no contradictory record appears. Strongest opposing consideration is the possibility that matched endplate-zone controls would also rise, relocating the effect to stress-sensitive endplates generally (see VASO-R011).

McNulty et al. 1994 (n=14, same lineage) showed mental arithmetic raising EMG at TP sites while adjacent control sites stayed quiet, without generalized tensing. Never replicated with modern methods or matched endplate-zone controls; no vascular endpoint. Strongest opposing consideration: Simons 2002 implies the silent controls may have been off-zone, so selectivity to “the knot” versus “any stressed endplate” is unproven.

One study (n=14, 1994) from the same lineage as Hubbard & Berkoff reports the effect, never replicated with modern instrumentation (VASO-E002); VASO-E033 is the essay restating it and adds nothing. The selectivity claim is the fragile part: Simons 2002 shows endplate noise occurs at some non-tender endplate-zone sites, so the "quiet" adjacent controls may simply have been off the endplate zone rather than demonstrating trigger-point specificity — exactly the confound VASO-R011 is designed to remove. The strongest opposing consideration is therefore that the entire localisation argument may be an artefact of control-site placement. If the effect is real it is striking evidence that a mental event writes to an addressable site, which is why replication matters more here than almost anywhere in the case.

One study (VASO-E002, n=14, 1994, same lineage as VASO-E001) reports the site-selective rise under mental arithmetic; VASO-E033 is a secondary restatement adding nothing. The selectivity — the whole content of the claim — is directly threatened by VASO-E031: if endplate noise occurs at non-tender endplate-zone sites, the "quiet" control needles may simply have sat off the endplate zone, so the stressor could be modulating endplate activity generally rather than a specific tender address. That confound is unresolved and is exactly what VASO-R011 is designed to settle. The claim survives as a single unreplicated observation with a plausible alternative reading of its control condition.

The entire basis is VASO-E002: one 1994 study, n = 14, from the same lab lineage as VASO-E001, never replicated with modern instrumentation, with VASO-E033 adding only a secondary restatement. The site-selectivity that makes this claim interesting is now specifically undermined: VASO-E031 shows endplate noise at non-tender endplate-zone sites, so the quiet control needles may simply have sat off the endplate zone rather than demonstrating that the stressor wrote to a tender address. The strongest consideration in the claim's favour is that no generalised muscle tensing was observed, which is hard to square with a whole-muscle sympathetic or motor response; but VASO-R011 exists because the matched-control experiment that would decide this has not been done.

VASO-E002 (moderate): in fourteen subjects, mental arithmetic increased EMG activity at trigger points while control sites in the same muscle stayed comparatively quiet, without generalized tensing. Same lineage as VASO-E001, so the two EMG studies constitute one line of evidence; no vascular endpoint; the essay's follow-up claims (relaxation training, phentolamine) have no located primary citation.

One study of fourteen subjects (VASO-E002, moderate) found mental arithmetic raised trigger-point EMG while control sites in the same muscle stayed comparatively quiet, without generalized tensing. It is the same lineage as VASO-E001, never replicated with modern instrumentation, and took no vascular measurement. Simons 2002 (VASO-E031) shows endplate noise occurs at non-tender endplate-zone sites, so the control sites may not have been matched for endplate-zone position — the selectivity may be for the endplate zone rather than the knot. Candidate follow-up papers on relaxation and alpha-blockade have been located but not retrieved.

McNulty and colleagues (1994) found mental arithmetic raised trigger-point EMG while control sites in the same muscle stayed comparatively quiet, without generalized tensing (VASO-E002, moderate). The essay's restatement (VASO-E033) mentions no control site and is read as background. n=14, same lineage as VASO-E001, never replicated, no vascular endpoint, and — after Simons 2002 — the control needle was not placed in a matched endplate-zone site, so selectivity for the trigger point over the endplate zone is untested. The relaxation and phentolamine follow-ups remain unretrieved.

VASO-E002 moderate (n = 14, one lineage, no vascular measurement, never replicated); VASO-E033 weak restatement. The control needle was not placed in a matched endplate-zone site, which VASO-E031 exposes as the missing comparator.

VASO-E002 (moderate, supports): mental arithmetic raised trigger-point EMG while same-muscle control sites stayed comparatively quiet, fourteen subjects, same lineage as the 1993 study. VASO-E033 is a weak restatement. No vascular measurement was taken and the control site was not matched to the endplate zone.

Mental arithmetic raised EMG at trapezius trigger points while control sites in the same muscle stayed comparatively quiet, in fourteen subjects, without generalized tensing (VASO-E002); the essay's restatement (VASO-E033) adds nothing. Same lineage as VASO-E001, never replicated, no vascular endpoint, and no matched endplate-zone control — an inference from VASO-E031 on the parent claim, stated as such.

One record: mental arithmetic raised trigger-point EMG while control sites in the same muscle stayed comparatively quiet in fourteen subjects (VASO-E002, moderate); the essay's restatement (VASO-E033) adds nothing. Same lineage as VASO-E001, never replicated, no vascular measurement, and the control needle was not placed in a matched endplate-zone site — an inference drawn from VASO-E031 on the sibling claim VASO-C002, disclosed as such.

One primary (VASO-E002, moderate): mental arithmetic raised activity at trigger points while control sites in the same muscle stayed comparatively quiet, without tensing, in fourteen subjects. Never replicated; no vascular measure. The essay's restatement (VASO-E033) is zero weight. Read beside VASO-E031 on the parent claim, the control site was not matched to the endplate zone — a disclosed cross-claim basis for holding the localization open.

Mental arithmetic raised trigger-point EMG while control sites in the same muscle stayed comparatively quiet, without general tensing (VASO-E002, moderate, n=14, same lineage as VASO-E001); VASO-E033 is the essay's restatement. No vascular measurement; the control needle was not placed in a matched endplate-zone site.

One study of fourteen subjects from the Hubbard lineage (VASO-E002, moderate) found mental arithmetic raised trigger-point activity while control sites stayed comparatively quiet; VASO-E033 restates it. The control needle was not placed in a matched endplate-zone site, so selection of the trigger point versus any endplate zone is open; never replicated; no vascular measurement.

One record: mental arithmetic raised trigger-point EMG while control sites in the same muscle stayed comparatively quiet, in fourteen subjects, one lineage (VASO-E002). VASO-E033 restates it. The control needle was not placed in a matched endplate-zone site, so selectivity for the trigger point over any endplate is open.

One record: mental arithmetic raised trigger-point EMG while control sites in the same muscle stayed comparatively quiet, in fourteen subjects from the Hubbard lineage (VASO-E002); the essay's restatement (VASO-E033) adds nothing. No matched endplate-zone control, no vascular endpoint, and the relaxation and phentolamine follow-ups remain unretrieved.

One study of fourteen subjects: mental arithmetic raised EMG activity at trapezius trigger points while control sites in the same muscle stayed comparatively quiet, without generalized tensing (VASO-E002, moderate); the essay's restatement (VASO-E033) adds no weight. Read beside the endplate-zone finding on the sibling claim (VASO-E031 on VASO-C002, a disclosed basis), the control site may not have been a matched endplate-zone site, so whether the stressor selected the trigger point or any endplate zone is open. Never replicated; no vascular measurement.

McNulty 1994 (VASO-E002, moderate): in fourteen subjects, mental arithmetic raised EMG at trigger points while control sites in the same muscle stayed comparatively quiet, without general tensing. Same lineage as Hubbard–Berkoff, never replicated, no vascular endpoint. The essay's restatement (VASO-E033) is at no independent weight and omits the control-site detail. Disclosed inference from a sibling record: Simons 2002 (VASO-E032 on VASO-C034 and VASO-C035) shows endplate noise at non-tender endplate-zone sites, so the control needle's zone placement is the open question.

McNulty et al. 1994 (VASO-E002) demonstrated in a controlled needle-EMG study that a mental arithmetic stressor selectively increased electrical activity at trapezius trigger points while adjacent control sites in the same muscle remained quiet. However, this finding rests on a single small trial (n=14) from the Hubbard lineage that has never been independently replicated using modern controls that electrically match the motor endplate zone. The strongest opposing consideration is that the silent control sites in McNulty 1994 may simply have been located outside the motor endplate zone rather than reflecting site-specific trigger-point addressability.

McNulty 1994 (E002, moderate) reports the selective stressor effect, but it is a single n=14 study from one research lineage, never replicated with modern instrumentation, with control sites that may have lain off the endplate zone and no vascular endpoint measured. Simons 2002 (E031) shows non-tender endplate-zone sites can be electrically active, making the site-selectivity precisely what the proposed control experiment (R011) must retest. The strongest opposing consideration is that the entire claim rests on one unrepeated observation.

VASO-E002 directly reports that mental arithmetic increased needle-EMG activity at trigger points while nearby controls remained comparatively quiet without generalized tensing. The study was small, has not been independently replicated with modern instrumentation, and did not ensure that control sites were matched within the motor endplate zone. The strongest opposing consideration is that stress-sensitive endplate or spindle activity can explain the observation without localized vascular storage.

McNulty 1994 (E002) showed mental arithmetic raised EMG at TP sites while adjacent controls stayed quiet (n=14, same lineage). No modern replication with matched endplate-zone controls or vascular endpoints. Strongest opposing consideration is that sympathetic drive to endplates or spindles fits without any vascular storage element.

The sole primary is McNulty et al. 1994 (n = 14): mental arithmetic raised needle-EMG activity at trapezius trigger points while control sites stayed comparatively quiet, without generalized tensing (E002). The essay's restatement (E033) is the same line of evidence, and the relaxation and phentolamine follow-ups are unretrieved. The finding has not been replicated with modern instrumentation, shares the Hubbard–Berkoff lineage, and measured no vascular endpoint. Non-tender endplate-zone sites also carry spontaneous activity (E031), so if the controls lay outside the endplate zone, the "selectivity" may be endplate versus non-endplate rather than trigger point versus muscle; the ledger cannot tell, and VASO-R011 is designed to find out. Strongest opposing consideration: this is a direct, controlled measurement within one muscle of exactly what the claim states, and no record contradicts it.

In fourteen subjects, mental arithmetic raised needle-EMG activity at trigger points while control sites stayed comparatively quiet (VASO-E002). The study comes from one lineage and was never replicated with modern instruments. It took no vascular measure, and its control was not a matched endplate-zone site. The essay's restatement (VASO-E033) adds nothing.
