An ERP examination of the different effects of sleep deprivation on exogenously cued and endogenously cued attention.

Background: Behavior and neuroimaging studies have shown selective attention to be negatively impacted by sleep deprivation. Two unresolved questions are (1) whether sleep deprivation impairs attention modulation of early visual processing or of a later stage of cognition and (2) how sleep deprivation affects exogenously versus endogenously driven selective attention.

Study Objectives: To investigate the time course and different effects of sleep deprivation on exogenously and endogenously cued selective attention.
