N1/awakening: Hypnic myoclonus (sleep start)
In N1 sleep, hypnic myoclonus (sleep start), clustering right where arousal breaks the surface near the exit toward wake. Cortical band theta spans 3.93–8.35 Hz; GABA leads, atonia state is "N/A", and this row's density score is 103.9.

Dataset readout: Hypnic myoclonus (sleep start) in N1 (awakening). Cortical window 3.93–8.35 Hz (theta). Atonia=N/A. Markers drive the text below — not dream-symbol meanings.
- brief autonomic flicker
- brief heart-rate spike
- exit-bound motor reboot
- falling sensation
Transmitters in this row:
- GABA
- norepinephrine
- orexin
Mechanism stack
- Cortically, this row runs theta at 3.93–8.35 Hz while hypnic myoclonus (sleep start), clustering right where arousal breaks the surface plays out in N1 sleep.
- The lead transmitter is GABA (inhibitory tone rises across cortical and spinal targets), alongside norepinephrine, orexin — this row's density score is 103.9.
- Dataset row #81618315: atonia 30/100, arousal 76/100, coherence 37/100 — the motor brake is thin, so movement can leak through, over an unsettled, choppy backdrop.
- On this awakening row the markers stack as "brief heart-rate spike" → "exit-bound motor reboot" → "falling sensation" → "brief autonomic flicker" — building toward the moment of waking.
- The Lab treats "brief autonomic flicker" here as awakening somatic evidence layered onto imagery for N1 sleep — treated as physiology here, not folklore.
Recall naming "brief autonomic flicker" in N1 sleep, near the exit toward wake, gets read by the Lab as body evidence, not as a dream symbol.
Felt on waking
On waking, the marker named most often is "brief autonomic flicker" with "brief heart-rate spike" close behind. Because this row sits at awakening in N1 sleep, it tends to dominate the first few seconds of being awake.

How Lab Search uses this row
Naming "brief autonomic flicker" — tied here to GABA activity shifts the Lab's N1-sleep reading toward physiology — the BODY line moves, the SIGNAL line does not chase a symbolic guess.

How to read N1/awakening: Hypnic myoclonus (sleep start)
This row is Hypnic myoclonus (sleep start) in N1 (awakening). Cortical window 3.93–8.35 Hz (theta). Atonia state: N/A. Density 103.9. Chart seed 81618315 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 30, arousal 76, coherence 37. Markers: brief autonomic flicker, brief heart-rate spike, exit-bound motor reboot, falling sensation. Transmitters tagged: GABA, norepinephrine, orexin. 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.

How Lab Search should use this row
Naming "brief autonomic flicker" — tied here to GABA activity shifts the Lab's N1-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 Hypnic myoclonus (sleep start) 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.
