Interhemispheric competition during sleep.

ABSTRACT: Our understanding of the functions and mechanisms of sleep remains incomplete, reflecting their increasingly evident complexity^1-3. Likewise, studies of interhemispheric coordination during sleep^4-6 are often hard to connect precisely to known sleep circuits and mechanisms. Here, by recording from the claustra of sleeping bearded dragons (Pogona vitticeps), we show that, although the onsets and offsets of Pogona rapid-eye-movement (REM_P) and slow-wave sleep are coordinated bilaterally, these two sleep states differ markedly in their inter-claustral coordination. During slow-wave sleep, the claustra produce sharp-wave ripples independently of one another, showing no coordination. By contrast, during REM_P sleep, the potentials produced by the two c
