Mechanisms of visual object recognition: monkey and human studies.

The feature-based representations of object images in the inferotemporal cortex of macaque monkeys have been further characterized by optical imaging experiments. Recently, the close correlation between the activity of inferotemporal cells and the perception of object images has been revealed by single-unit recordings from behaving monkeys. The human homologue of the monkey inferotemporal cortex has been identified through use of new non-invasive techniques.
