Fleeting sleep interruptions may help brain reset

Brief, seconds-long microarousals during deep sleep “ride on the wave” of locus coeruleus activity in mice and correlate with periods of waste clearing and memory consolidation, new research suggests.

New method reignites controversy over brain clearance during sleep

Tracers injected directly into mouse brain tissue instead of the cerebrospinal fluid show that brain clearance slows during sleep and under anesthesia, according to a study published last week—but proponents of the glymphatic system theory take issue with the technique.
