Phys. Rev. Lett. 88, 218101 (2002) [4 pages]Noise-Induced Entrainment and Stochastic Resonance in Human Brain WavesReceived 27 December 2001; published 10 May 2002 We present the first observation of stochastic resonance (SR) in the human brain’s visual processing area. The novel experimental protocol is to stimulate the right eye with a subthreshold periodic optical signal and the left eye with a noisy one. The stimuli bypass sensory organs and are mixed in the visual cortex. With many noise sources present in the brain, higher brain functions, e.g., perception and cognition, may exploit SR. © 2002 The American Physical Society URL:
