The perirhinal cortex is known to play a role in recognition memory and visual perception of objects. A recent single-unit recording study adds to our understanding of perirhinal cortex function, suggesting that it may also play a role in evaluating the significance of objects in a context-dependent manner.

Acquiring the significance of events based on reward-related information is critical for animals to survive and to conduct social activities. The importance of the perirhinal cortex for reward-related information processing has been suggested. To examine whether or not neurons in this cortex represent reward information flexibly when a visual stimulus indicates either a rewarded or unrewarded o...

We compared single-cell activities in perirhinal cortex (PRh) as well as adjacent visual cortex (area TE) across two tasks. One task required the monkey to identify any stimulus repetition within a sequence of object stimuli. In the other task, the same stimuli were presented, but the monkey didn't have to remember them. PRh responses during the object-memory task were elevated relative to thos...

The word “Layers” refers to the deferent layers within a communications system—such as an organization’s or person’s website—that together make communication possible. The idea of “Layers” is attributed to Yochai Benkler, Professor of Law at New York University, who first used it to describe a communications system that is divided in three distinct layers: 1. The “physical” layer across which c...
