Study Summary
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.
Primary Outcome
Visual sensitivity changes will be assessed behaviorally using a psychophysical orientation detection task. Participants will be asked to detect the orientation of a Gabor patch embedded in visual noise. The outcome measure will be the signal-to-noise ratio (SNR) threshold at which participants can reliably detect the target orientation (typically defined as 75% correct performance). Lower SNR thresholds indicate greater visual sensitivity.
