Prestriate afferents to inferior temporal cortex: an HRP study

Brain Res. 1980 Feb 17;184(1):41-55. doi: 10.1016/0006-8993(80)90586-7.

Abstract

The inferior temporal (IT) cortex of 6 macaques was injected with horseradish peroxidase. HRP-labeled cells were found throughout IT cortex itself (outside the injection area) but were not found in the polysensory areas that surround IT dorsally, anteriorly and ventrally. Posterior to IT, labeled cells were found in the anterior parts of prestriate cortex. In one animal, the anterior prestriate region was injected with HRP. Labeled cells were then found in the regions of posterior prestriate cortex that receive direct projections from striate cortex. These results suggest that IT cortex receives information from striate cortex after at least two stages of processing in prestriate cortex.
