Expert birdwatchers show structural brain differences compared to novices, suggesting the hobby reshapes neural pathways similar to learning a language or instrument. These changes may help build cognitive reserve against age-related decline. A study highlights increased brain activity and complexity in key regions among skilled birders.

Researchers have discovered that the brain does not gradually fall asleep but instead undergoes a rapid transition from wakefulness to sleep in just minutes. This tipping point, identified through EEG data from over 1,000 people, challenges the long-held view of sleep onset as an incremental process. The findings could enhance understanding and treatment of sleep disorders like insomnia.
