When we wake from the dream-laden phase of sleep, the brain boots up step by step. The first brain regions to rouse are those associated with executive function and decision-making, located at the front of the head. A wave of wakefulness then spreads to the back, ending with an area associated with vision. This precise understanding of how the brain transitions from slumber to alertness could help to manage sleep inertia - the grogginess that many people feel when hitting the snooze button.
