Pre-REM atonia ramp in N2 sleep (mid-cycle)
While the night is already underway, pre-REM atonia ramp, recurring deep inside the cycle plays out under N2 sleep at 10.66–16.46 Hz (sigma). Chemistry here runs GABA, glutamate, glycine, and the markers people report are eye movement precursors, face slackening, progressive limb heaviness. Gauges read 64/40/58 (atonia/arousal/coherence).

Dataset readout: Pre-REM atonia ramp in N2 (mid-cycle). Cortical window 10.66–16.46 Hz (sigma). Atonia=partial_failure. Markers drive the text below — not dream-symbol meanings.

- face slackening
- progressive limb heaviness
Mechanism stack
- Cortically, this row runs sigma at 10.66–16.46 Hz while pre-REM atonia ramp, recurring deep inside the cycle plays out in N2 sleep.
- GABA leads the chemistry here (inhibitory tone rises across cortical and spinal targets); glutamate, glycine also show up; density for this row is 109.8.
- Dataset row #12590920: atonia 64/100, arousal 40/100, coherence 58/100 — the motor brake is only partial, against a moderately organized backdrop.
- On this mid-cycle row the markers stack as "eye movement precursors" → "face slackening" → "progressive limb heaviness" — holding a steady pattern well inside the cycle.
- The Lab treats "eye movement precursors" here as mid-cycle somatic evidence layered onto imagery for N2 sleep — scored as hardware, not metaphor.
"eye movement precursors" logged in the mid-cycle window shifts how Lab Search ranks N2 sleep pages: body signal first, imagery second.
Felt on waking
On waking, the marker named most often is "eye movement precursors" with "face slackening" close behind. Because this row sits at mid-cycle in N2 sleep, it usually repeats quietly without breaking sleep, so it is easy to miss until you look for it.
Related physiology
This row connects to Atonia lock — the GABA–glycine brake that holds skeletal muscle offline during REM.
How Lab Search uses this row
The Lab does not look up "eye movement precursors" in a symbol table — tied here to GABA activity; it uses it to weight the BODY line of your N2 reading toward mechanism.

How to read Pre-REM atonia ramp in N2 sleep (mid-cycle)
This row is Pre-REM atonia ramp in N2 (mid-cycle). Cortical window 10.66–16.46 Hz (sigma). Atonia state: partial_failure. Density 109.8. Chart seed 12590920 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 64, arousal 40, coherence 58. Markers: eye movement precursors, face slackening, progressive limb heaviness. Transmitters tagged: GABA, glutamate, glycine. 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 "eye movement precursors" with "face slackening" close behind. Because this row sits at mid-cycle in N2 sleep, it usually repeats quietly without breaking sleep, so it is easy to miss until you look for it. "eye movement precursors" logged in the mid-cycle window shifts how Lab Search ranks N2 sleep pages: body signal first, imagery second.

How Lab Search should use this row
The Lab does not look up "eye movement precursors" in a symbol table — tied here to GABA activity; it uses it to weight the BODY line of your N2 reading toward mechanism. Then open Decode if you also have a plot. The plot is optional; the body line is not.
This utility will not treat Pre-REM atonia ramp 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.
