Paper Abstract

We report the results of two psychophysics experiments showing that the human brain can make use of externally added noise for behavioral responses. Subjects were instructed to respond to changing gray level signals presented to their right eye. The behavioral responses were optimized by presenting randomly changing gray level noise to their left eye. The results indicate that the behavioral stochastic resonance occurs at the cortical level where information from both eyes merges together.
