How the brain wakes up from sleep – and produces that morning feeling

10 months ago

The study reveals how the brain transitions from sleep to wakefulness, showing an ordered wave of activation from front to back.
Frontal brain regions associated with executive function and decision-making wake up first, followed by areas towards the back, ending with vision-related regions.
Findings suggest waking up is not simply the reverse of falling asleep; it's a more structured process.
The research was conducted using 256 scalp sensors on 20 participants, recording brain activity during spontaneous and alarm-induced awakenings.
The study was published in Current Biology and could help manage sleep inertia, the grogginess felt upon waking.
