Visually induced gamma band responses in the human EEG - Expression of cortical stimulus representation?<br />The features of a visual stimulus are processed in different regions of the visual cortex with no direct axonal connections. Therefore, neurons in the distributed processing areas must be connected in some way to form the physiological substrate of the percept. On the basis of theoretical considerations and animal experiments, it has been proposed that synchronization of neuronal oscillatory firing patterns in the gamma band range (above 30 Hz) might be essential in linking the anatomically distant cell assemblies that represent the various features of the stimulus. The present work reports on three experiments in which the functional relevance of induced gamma band responses were investigated in the human EEG. Using an identical stimulation design, as used in animal studies, it was demonstrated that human induced gamma band responses resembled those reported from intracortical recordings from animals. It was further shown that alpha and gamma band activities differed in temporal characteristics as well as in topographical features, indicating the representation of different cortical functional states. In accordance with previous animal and human experimental findings, a complex moving stimulus was related to a suppression of induced gamma band activity as opposed to a standing complex stimulus.
