Brain and Visual Perception

This chapter presents a paper entitled “Integrative Action in the Cat's Lateral Geniculate Body”. This paper represented a rare opportunity to study directly the difference between the information entering a structure and the information leaving it. In the study, receptive fields in the optic tract and the lateral geniculate body were compared. Cells with receptive fields within or near the area centralis tended to have smaller field centers and stronger suppression by the receptive field periphery than cells with their fields in more peripheral regions of the retina. Clustered firing in the form of brief bursts of spikes at high frequency was observed under thiopental anesthesia. From simultaneous records, it appeared that a single impulse in an optic-tract fiber could give rise to a cluster of impulses in a geniculate cell.

Keywords:   cat lateral geniculate, retina, thiopental, integrative action, optic tract, clustered firing
