Interhemispheric competition during sleep

Bilaterally implanted NeuroNexus A1x32-Poly2-10mm-50s-177-H32_21mm probes were used to study interhemispheric coordination during sleep. Recordings in the bearded dragon claustrum showed that hemispheres are not coordinated during slow wave sleep, but have precisely coordinated, asynchronous sharp wave ripples during REM sleep. Further experiments in the Nature paper by Lorenz Fenk and collaborators with Gilles Laurent’s lab at Max Planck Institute for Brain Research suggest that interhemispheric competition likely originates from a nucleus corresponding to what is known as the Imc in birds.
