Abstract

Background and Purpose: Aim of our study was to evaluate cerebral hemodynamic changes during performance of attention tasks and to correlate them with reaction time (RT) and percentage of right answers. Methods: Mean flow velocity (MFV) in middle cerebral arteries was monitored in 30 subjects by transcranial Doppler during tonic alertness, phasic alertness, focused and divided attention tasks. Results: Mean flow velocity increase was significantly higher during divided attention with respect to other tasks (P
