Alpha intrusion into NREM · sigma 11.26–16.38 Hz · N2

How to read Alpha intrusion into NREM · sigma 11.26–16.38 Hz · N2

This row is Alpha intrusion into NREM in N2 (awakening). Cortical window 11.26–16.38 Hz (sigma). Atonia state: N/A. Density 107.2. Chart seed 31453077 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.

Gauges on this page: atonia 27, arousal 83, coherence 38. Markers: brief autonomic flicker, exit-bound motor reboot, light sleep feel, muscle tension pockets. Transmitters tagged: GABA, glutamate, norepinephrine. Those fields are why two “similar” titles are not duplicates. If a marker did not happen to you, say so — do not wear the whole row.

What the body is doing — not what the image “means”

On waking, the marker named most often is "brief autonomic flicker" with "exit-bound motor reboot" close behind. Because this row sits at awakening in N2 sleep, it tends to dominate the first few seconds of being awake. The Lab treats "brief autonomic flicker" as a mechanism marker when it shows up near the exit toward wake in N2 sleep — not something to look up in a dictionary.

1. N2 sleep frames alpha intrusion into NREM, clustering right where arousal breaks the surface, against a sigma trace of 11.26–16.38 Hz.
2. Chemistry is GABA-led here (inhibitory tone rises across cortical and spinal targets), with glutamate, norepinephrine co-listed; density 107.2 on this row.
3. Dataset row #31453077: atonia 27/100, arousal 83/100, coherence 38/100 — the brake is loose enough to slip, against a jagged, low-coherence backdrop.
4. On this awakening row the markers stack as "exit-bound motor reboot" → "light sleep feel" → "muscle tension pockets" → "brief autonomic flicker" — sharpening as arousal climbs toward the surface.
5. The Lab treats "brief autonomic flicker" here as awakening somatic evidence layered onto imagery for N2 sleep — treated as physiology here, not folklore.

How Lab Search should use this row

Naming "brief autonomic flicker" — tied here to GABA activity shifts the Lab's N2-sleep reading toward physiology — the BODY line moves, the SIGNAL line does not chase a symbolic guess. Then open Decode if you also have a plot. The plot is optional; the body line is not.

This utility will not treat Alpha intrusion into NREM as a spirit, a pregnancy test, or a death omen. It will treat it as a stage-bound somatic metric. If symptoms are nightly, worsening, or include dream enactment, that is clinical, not catalog.

A note from Vigen

I am Vigen. I left Alpha intrusion into NREM · sigma 11.26–16.38 Hz · N2 in the catalog because the gauges (27/83/38) plus markers (brief autonomic flicker, exit-bound motor reboot, light sleep feel, muscle tension pockets) are enough to be useful. If they were not, this URL would stay noindex.
