Sleep-related bruxism (jaw clenching) in N2 sleep (mid-cycle)
While the night is already underway, sleep-related bruxism (jaw clenching), recurring deep inside the cycle plays out under N2 sleep at 11–16 Hz (sigma). Chemistry here runs dopamine, norepinephrine, GABA, and the markers people report are jaw tension, tooth grinding, temporalis tightness. Gauges read 30/55/60 (atonia/arousal/coherence).

Dataset readout: Sleep-related bruxism (jaw clenching) in N2 (mid-cycle). Cortical window 11–16 Hz (sigma). Atonia=N/A. Markers drive the text below — not dream-symbol meanings.
- jaw tension
- tooth grinding
- temporalis tightness
Transmitters in this row:
- dopamine
- norepinephrine
- GABA
Mechanism stack
- Sleep-related bruxism (jaw clenching), recurring deep inside the cycle sits inside N2 sleep, with cortical activity running sigma at 11–16 Hz.
- Chemistry is dopamine-led here (dopaminergic bursts can tag salience without waking narrative), with norepinephrine, GABA co-listed; density 109 on this row.
- Dataset row #10005: atonia 30/100, arousal 55/100, coherence 60/100 — the motor brake is thin, so movement can leak through, against a moderately organized backdrop.
- On this mid-cycle row the markers stack as "jaw tension" → "temporalis tightness" → "tooth grinding" — recurring without much variation mid-stretch.
- The BODY line on this page leans on "jaw tension" for this mid-cycle/N2 row — scored as hardware, not metaphor.
"jaw tension" 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 "jaw tension" with "tooth grinding" 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.

How Lab Search uses this row
The Lab does not look up "jaw tension" in a symbol table — tied here to dopamine activity; it uses it to weight the BODY line of your N2 reading toward mechanism.

How to read Sleep-related bruxism (jaw clenching) in N2 sleep (mid-cycle)
This row is Sleep-related bruxism (jaw clenching) in N2 (mid-cycle). Cortical window 11–16 Hz (sigma). Atonia state: N/A. Density 109. Chart seed 10005 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 30, arousal 55, coherence 60. Markers: jaw tension, tooth grinding, temporalis tightness. Transmitters tagged: dopamine, norepinephrine, GABA. 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 "jaw tension" with "tooth grinding" 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. "jaw tension" 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 "jaw tension" in a symbol table — tied here to dopamine 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 Sleep-related bruxism (jaw clenching) 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.
