Popis: | Face recognition is highly proficient in humans and other social primates; it emerges in infancy, but the development of the neural mechanisms supporting this behaviour is largely unknown. We use blood-volume functional MRI to monitor longitudinally the responsiveness to faces, scrambled faces, and objects in macaque inferotemporal cortex (IT) from 1 month to 2 years of age. During this time selective responsiveness to monkey faces emerges. Some functional organization is present at 1 month; face-selective patches emerge over the first year of development, and are remarkably stable once they emerge. Face selectivity is refined by a decreasing responsiveness to non-face stimuli. Development of neural circuits for face recognition is not well studied in primates. Here the authors longitudinally track responses to faces in monkeys from about a month of age to two years and demonstrate that face-selective responses emerge in inferotemporal cortex early and gradually stabilize over time. |
