Effect of maintaining neck flexion on saccadic reaction time and sensory evoked potential

Abstract

  We have been investigated neck flexion effect on the brain activation. In the present paper, we showed the recording and analysis techniques of saccadic reaction time and sensory evoked potentials, which are indices of the brain activation. Furthermore, we indicated the following findings: (1) shortening mechanism of saccadic reaction time associated with maintaining neck flexion, (2) formation of that mechanism through saccadic training accompanied by maintenance of neck flexion, (3) age-related change in the shortening of the reaction time, and (4) neck flexion effect on latency and amplitude of sensory evoked potential.
