Physiology of morphologically identified cells in the posterior caudal lobe of the mormyrid cerebellum.

abstract：:The hypothesis that gamma-band oscillations are related to the representation of an environmental scene in the cerebral cortex after binding of corresponding perceptual elements is currently under discussion. One question is how the sensory system reacts to a fast change in the scene if perceptual elements are rigidly...
