Mammalian sleep plays a crucial role in maintaining optimal brain health by facilitating the clearance of toxic proteins that accumulate during wakefulness. The glymphatic system, responsible for flushing cerebral spinal fluid (CSF) through the brain, is particularly active during non-rapid eye movement (NREM) sleep in mice. In humans, functional magnetic resonance imaging (fMRI) has revealed an increase in ventricular CSF flow during NREM sleep. However, the relationship between sleep and CSF flow remains unexplored in avian species.Our study breaks new ground by employing fMRI to observe nat
