Visual properties of cells in anterior dorsal ventricular ridge of turtle.
Single units in the anterior dorsal ventricular ridge (ADVR), a structure in the major afferent visual pathway of turtle, were investigated electrophysiologically for response properties to varied light patterns. The majority of cells responded to a broad range of spatially, temporally, and chromatically varied stimuli over most of the monocular visual field. One category of cells, seemingly specialized for 'novelty' detection, indicates one possible role for ADVR in visual sensory processing.
