Tegmental atrophy in isolated REM sleep behaviour disorder: ex vivo MRI–informed in vivo imaging
Isolated rapid eye movement (REM) sleep behaviour disorder (iRBD) is an early-stage synucleinopathy characterized by brainstem pathology. In rodents, the pontine tegmentum contains a REM sleep centre, the sublaterodorsal nucleus, which expresses corticotropin-releasing hormone binding protein (CRHBP). While the invol...
