Many recent studies have examined the neural basis of category learning. Behavioral
neuroscience results suggest that both the prefrontal cortex and the basal ganglia play …

Examining the receptive fields of brain signals can elucidate how information impinging on
the former modulates the latter. We applied this time-honored approach in early vision to the …

While brain imaging studies emphasized the category selectivity of face-related areas, the
underlying mechanisms of our remarkable ability to discriminate between different faces are …

Recent studies have suggested a profound influence of category learning on visual
perception, resulting in independent processing of previously integral dimensions. The …

We read jubmled wrods effortlessly, but the neural correlates of this remarkable ability
remain poorly understood. We hypothesized that viewing a jumbled word activates a visual …

The organizational principles of the object space represented in the human ventral visual
cortex are debated. Here we contrast two prominent proposals that, in addition to an …

In this thesis, I describe a quantitative model that accounts for the circuits and computations
of the feedforward path of the ventral stream of visual cortex. This model is consistent with a …

Real-world expertise provides a valuable opportunity to understand how experience shapes
human behavior and neural function. In the visual domain, the study of expert object …

Recent work suggests that a key function of the hippocampus is to predict the future. This is
thought to depend on its ability to bind inputs over time and space and to retrieve upcoming …

This paper investigates the classification of shapes into broad natural categories such as
animal or leaf. We asked whether such coarse classifications can be achieved by a simple …
