Noradrenergic modulation of human cortex excitability by the presynaptic alpha(2)-antagonist yohimbine.

abstract：:It has recently been shown that noise can improve the detection of stimuli in several sensory modalities. We herein investigated whether visual contrast detection sensitivity can be improved by adding a certain amount of noise. The contrast detection thresholds of a light changing brightness periodically were measured...
