New neuroscience research reveals that individual variations in brain connectivity impact the amount of sleep needed for optimal functioning. People with stronger connectivity in brain networks related to attention and memory tend to require less sleep, while those with weaker connectivity need more to maintain cognitive performance.
Functional brain connectivity as a predictor of sleep duration
A new study found that functional brain connectivity can predict sleep duration in both youth and adults. Using data from fMRI scans, researchers identified patterns in brain networks that correlate with self-reported sleep in adults and objectively measured sleep in adolescents. These connectivity patterns, particularly in resting-state networks, were robust predictors of how much sleep an individual typically gets and generalized across different populations.
