Distinct, coordinated activity in large sets of neurons can predict the future behaviors of rats, a new study reports. Based on the findings, researchers have created a "dictionary" that links brain activity patterns to simple behavioral outcomes.
During deep sleep, the presence of an unfamiliar voice elicits more K-complexes, a type of brain wave linked to sensory perturbances during sleep, compared to the sound of a familiar voice.
Video game players are faster and more accurate in their responses, and excel at decision-making tasks. The differences in accuracy and reaction time correlated with enhanced brain activity.
