A study in Nature Neuroscience shows that the moments of failed attention we experience after sleep deprivation reflect brief ‘sleep-like’ episodes in the brain, corresponding to a brain- and body-wide event with altered brain activity, pupil size and brain fluid movement. #neuroskyence 🧪
Attentional failures after sleep deprivation are locked to joint neurovascular, pupil and cerebrospinal fluid flow dynamics - Nature Neuroscience
Yang et al. show that moments of failed attention we experience after sleep deprivation reflect brief ‘sleep-like’ episodes in the brain, corresponding to a brain- and body-wide event with altered brain activity, pupil size and brain fluid movement.

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.
