This asymmetry is highly patient-specific and supports the hypothesis that generalized discharges are shaped by delimited areas of cortex.

Can you learn while sleeping? Does sleep help you solve problems? What is the effect of sleep on brain metabolism?
--> my last editorial @braincomms.bsky.social

Sleep is not a homogenous state - just like wake. Asking the role of sleep is as fair as asking the role of wake!
