TL;DR
It is shown that monkeys' ability to recognize degraded objects was improved by several days of practice with these objects, and this improvement was reflected in the activity of neurons in the prefrontal cortex, a brain region critical for a wide range of visual behaviors.
Abstract
The perception and recognition of objects are improved by experience. Here, we show that monkeys' ability to recognize degraded objects was improved by several days of practice with these objects. This improvement was reflected in the activity of neurons in the prefrontal (PF) cortex, a brain region critical for a wide range of visual behaviors. Familiar objects activated fewer neurons than did novel objects, but these neurons were more narrowly tuned, and the object representation was more resistant to the effects of degradation, after experience. These results demonstrate a neural correlate of visual learning in the PF cortex of adult monkeys.

The results suggest that IT neurons can develop a complex receptive field organization as a consequence of extensive training in the discrimination and recognition of objects, and support the idea that a population of neurons tuned to a different object aspect, and each showing a certain degree of invariance to image transformations--may encode at least some types of complex three-dimensional objects.
