Although some change in the neural representation of an object must occur as it becomes familiar, the nature of this change is not fully understood. In humans, it has been shown that the N170-an evoked visual potential-is enhanced for classes of objects for which people have visual expertise. In this study, we explored whether monkeys show a similar… (More)
Using visually complex stimuli, three monkeys learned visual exclusive-or (XOR) tasks that required detecting two way visual feature conjunctions. Monkeys with passive exposure to the test images, or prior experience, were quicker to acquire an XOR style task. Training on each pairwise comparison of the stimuli to be used in an XOR task provided nearly… (More)

Fisch et al. report in this issue of Neuron the results of an investigation of the neural correlates of conscious perception. They find an early, dramatic, and long-lasting gamma response in high-level visual areas, when (and only when) a rapidly presented image is perceived.
