And it's not just individual variation: this phase-locking pattern becomes more consistent across the scalp and across individuals in N2, SWS, and REM sleep.

We found that E:I coupling to respiration shifts as people fall asleep. This means that in sleep, respiration modulates 1/f slope in a different phase than during wakefulness
Wake: 1/f slope peaks during expiration → peak cortical inhibition
Sleep: 1/f slope peaks during inspiration

Using overnight EEG and respiration recordings from 23 participants, we tracked aperiodic brain activity (1/f slope), a marker of excitation-inhibition (E:I) balance, across sleep stages and respiratory phase.

Proudly representing the Schreiner lab!
