REM/mid-cycle: Fragmented REM with micro-arousals
Inside an established cycle segment, the marker named most often is "brief body shifts" — the clearest signal for fragmented REM with micro-arousals, recurring deep inside the cycle. Band theta at 3.79–7.55 Hz; GABA chemistry; density 102.4.

Dataset readout: Fragmented REM with micro-arousals in REM (mid-cycle). Cortical window 3.79–7.55 Hz (theta). Atonia=partial_failure. Markers drive the text below — not dream-symbol meanings.
- brief body shifts
- dry mouth on wakelets
- stable stage somatic quiet
- start-stop REM feel
Transmitters in this row:
- GABA
- acetylcholine
- norepinephrine
Mechanism stack
- Cortically, this row runs theta at 3.79–7.55 Hz while fragmented REM with micro-arousals, recurring deep inside the cycle plays out in REM sleep.
- GABA leads the chemistry here (inhibitory tone rises across cortical and spinal targets); acetylcholine, norepinephrine also show up; density for this row is 102.4.
- Dataset row #32884536: atonia 59/100, arousal 60/100, coherence 61/100 — inhibition sits at a middle setting, over a middling, mixed backdrop.
- On this mid-cycle row the markers stack as "brief body shifts" → "dry mouth on wakelets" → "stable stage somatic quiet" → "start-stop REM feel" — repeating steadily through an already-stable stretch.
- The BODY line on this page leans on "brief body shifts" for this mid-cycle/REM row — scored as hardware, not metaphor.
Recall naming "brief body shifts" 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 "brief body shifts" with "dry mouth on wakelets" close behind. Because this row sits at mid-cycle in REM sleep, it usually repeats quietly without breaking sleep, so it is easy to miss until you look for it.

How Lab Search uses this row
The Lab does not look up "brief body shifts" in a symbol table — tied here to GABA activity; it uses it to weight the BODY line of your REM reading toward mechanism.

How to read REM/mid-cycle: Fragmented REM with micro-arousals
This row is Fragmented REM with micro-arousals in REM (mid-cycle). Cortical window 3.79–7.55 Hz (theta). Atonia state: partial_failure. Density 102.4. Chart seed 32884536 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 59, arousal 60, coherence 61. Markers: brief body shifts, dry mouth on wakelets, stable stage somatic quiet, start-stop REM feel. Transmitters tagged: GABA, acetylcholine, 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
The Lab does not look up "brief body shifts" in a symbol table — tied here to GABA activity; it uses it to weight the BODY line of your REM 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 Fragmented REM with micro-arousals 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.
