Contribution of temporal preparation and processing speed to simple reaction time in persons with Alzheimer's disease and mild cognitive impairment.

abstract：:We find a spatially asymmetric allocation of attention in patients with traumatic brain injury (TBI) despite the lack of obvious asymmetry in neurological indicators. Identification performance was measured for simple spatial patterns presented briefly to a locus 5 degrees into the left or right hemifield, after precu...
