Visual properties of neurons in inferotemporal cortex of the Macaque.

has been made in understanding the physi-ology of one of the most fundamental as-pects of human experience: perception of the visual world. It is now clear that the retina and visual pathways do not simply transmit a mosaic of Iight and dark to some central sensorium. Rather, even at the ret-inal level, specific features of visual stimuli are detected and their presence communi-cated to the next level. In cats and monkeys, the geniculostriate visual system consists of a series of converging and diverging connec-tions such that at each successive tier of processing mechanism, single neurons re-spond to increasingly more specific visual
