Gamma response of the brain: a multifunctional oscillation that represents bottom-up with top-down processing

Int J Psychophysiol. 2001 Jan;39(2-3):137-50. doi: 10.1016/s0167-8760(00)00137-9.


This paper deals with the functional correlates of the gamma response of the brain. A critical review of the literature findings reveals the existence of two types of gamma responses: an early gamma that fulfills sensory functions and a late gamma that fulfills perceptual-cognitive functions. However, even the early gamma shows individual differences. Such a finding points to the existence of top-down influences on sensory processes and to a parallel-processing model for brain function.
