Prefrontal cortex and inferior temporal cortex interact in support of a wide variety of learning and memory functions. In macaque monkeys, a disconnection of prefrontal and temporal cortex produces severe new learning impairments in a range of complex learning tasks such as visuo-motor conditional learning and object-in-place scene learning. The retrograde effects of this disconnection, however, have never been fully examined. We therefore assessed the postoperative retention of 128 preoperat...
