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
Neurons in inferotemporal cortex (area TE) of the monkey had visual receptive fields which were very large (greater than 10 by 10 degrees) and almost always included the fovea. Some extended well into both halves of the visual field, while others were confined to the ipsilateral or contralateral side. These neurons were differentially sensitive to several of the following dimensions of the stimulus: size and shape, color, orientation, and direction of movement.
