yup, could mirror the strong anatomical connections between central thalamus and frontal regions described in animal models. functional connectivity with scalp eeg shows state-dependent elevated connectivity in the specific frq band, but not region-specific.

Agree! A thalamic origin of a cortical rhythm picked up by scalp EEG could be plausible. In our data, however, modulation of scalp power in the frq band of the thalamic oscillation was not obvious on the group level (see below), just like in the non-invasive EEG data you referred to (Snipes, 2024).

The novel oscillation is specific to microstates within REM sleep. Phasic REM, but not tonic REM, is tightly linked to the oscillation: bursts of the thalamic oscillations co-occur with eye movements during REM sleep.

The novel oscillation is remarkably consistent and its presence is robust across the cohort. We clearly identify it in Central Thalamus, but not in other thalamic nuclei.

We find that human Central Thalamus is synchronized via a clear and persistent brain-state-specific oscillation which only occurs in wakefulness and REM sleep.

The figure shows the novel oscillation (~30 Hz) during wake and REM. In NonREM, the well known sleep spindles dominate.
