Abstract (summary)

The purpose of the dissertation was to assess hemispheric attention and how it is influenced by time-of-day, sleep deprivation, and recovery sleep after sleep deprivation. The research employs the Lateralized Attention Network Task (LANT), a behavioral task used to assess three networks of attention (Conflict resolution, Orienting, and Alerting) in each of the cerebral hemispheres. It was shown that each of the networks show independent diurnal rhythms, distinct neural dynamics during sleep deprivation, and different rates of recovery after prolonged sleep deprivation. The results suggest that attention networks in the left and right hemispheres are independent and that future studies should take into account laterality, time-of-day, and degree of sleep deprivation when studying attention.
