REM-linked genital engorgement (physiological) · theta 4–8 Hz · REM
In REM sleep, rEM-linked genital engorgement (physiological), repeating well inside an established stretch in the mid-cycle window. Cortical band theta spans 4–8 Hz; acetylcholine leads, atonia state is "preserved", and this row's density score is 91.

Dataset readout: REM-linked genital engorgement (physiological) in REM (mid-cycle). Cortical window 4–8 Hz (theta). Atonia=preserved. Markers drive the text below — not dream-symbol meanings.
- genital vascular engorgement
- pelvic warmth
- preserved limb atonia
- acetylcholine
- nitric-oxide pathway
- norepinephrine
Mechanism stack
- REM sleep frames rEM-linked genital engorgement (physiological), repeating well inside an established stretch, against a theta trace of 4–8 Hz.
- Chemistry is acetylcholine-led here (cholinergic REM drive elevates cortical activation), with nitric-oxide pathway, norepinephrine co-listed; density 91 on this row.
- Dataset row #10016: atonia 90/100, arousal 28/100, coherence 70/100 — the brake is locked down tight, against a stable, well-organized backdrop.
- On this mid-cycle row the markers stack as "genital vascular engorgement" → "pelvic warmth" → "preserved limb atonia" — repeating steadily through an already-stable stretch.
- "genital vascular engorgement" gets weighted as mid-cycle body evidence for REM sleep in Lab Search — treated as physiology here, not folklore.
Recall naming "genital vascular engorgement" in REM sleep, in the mid-cycle window, gets read by the Lab as body evidence, not as a dream symbol.

Felt on waking
On waking, the marker named most often is "genital vascular engorgement" with "pelvic warmth" close behind. Because this row sits at mid-cycle in REM sleep, it tends to sit in the background, noticed only in hindsight the next morning.

This row connects to Cortex & EEG — the wake-like cortical activity that drives memory work in this stage.
How Lab Search uses this row
Naming "genital vascular engorgement" — tied here to acetylcholine activity shifts the Lab's REM-sleep reading toward physiology — the BODY line moves, the SIGNAL line does not chase a symbolic guess.

How to read REM-linked genital engorgement (physiological) · theta 4–8 Hz · REM
This row is REM-linked genital engorgement (physiological) in REM (mid-cycle). Cortical window 4–8 Hz (theta). Atonia state: preserved. Density 91. Chart seed 10016 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 90, arousal 28, coherence 70. Markers: genital vascular engorgement, pelvic warmth, preserved limb atonia. Transmitters tagged: acetylcholine, nitric-oxide pathway, 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.

How Lab Search should use this row
Naming "genital vascular engorgement" — tied here to acetylcholine activity shifts the Lab's REM-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 REM-linked genital engorgement (physiological) 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 REM-linked genital engorgement (physiological) · theta 4–8 Hz · REM in the catalog because the gauges (90/28/70) plus markers (genital vascular engorgement, pelvic warmth, preserved limb atonia) are enough to be useful. If they were not, this URL would stay noindex.
