Generalization and Specificity of Visual Learning During Sleep

CompletedNA

Sponsor: Brown University

Conditions: Visual Learning, Healthy Volunteers

Interventions: Visual perceptual learning

Countries: United States

A growing body of evidence suggests that sleep facilitates and is beneficial to perceptual learning. However, the underlying mechanism of this facilitatory action is largely unknown. One must know what type of processing occurs during sleep to clarify the mechanism of sleep facilitating perceptual learning. For this purpose, investigators will obtain highly localized spatio-temporal information about brain activation during sleep using magnetic resonance imaging (MRI) and polysomnography (PSG) measurement.
