Synaptic depression induced by pharmacological activation of metabotropic glutamate receptors in the perirhinal cortex in vitro

, 1999
The perirhinal cortex is crucially involved in various forms of learning and memory. Decrements in neuronal responsiveness occur in the perirhinal cortex with stimulus repetition during visual recognition performance.

Anterograde versus Retrograde Effects of Damage to Identified Learning and Memory Systems during Acquisition, Retention, and Re-Acquisition of an Instrumental Visual Discrimination Task: Dorsal Striatum, Perirhinal Cortex, and Hippocampus

Journal of Integrative Neuroscience
Background: The goal of these experiments was to determine which learning and memory system(s) were necessary for the retention of visual discriminations and subsequent acquisition of a second problem.

Slow and Fast (Gamma) Neuronal Oscillations in the Perirhinal Cortex and Lateral Amygdala

, 2001
Most lesion studies emphasize the distinct contributions of the amygdala and perirhinal cortex to memory. Yet, the presence of strong reciprocal excitatory projections between these two structures suggests that they are functionally coupled.

Impaired object recognition with increasing levels of feature ambiguity in rats with perirhinal cortex lesions

, 2004
It has been proposed that the perirhinal cortex is involved in the representation of the characteristics of objects. In particular it has been proposed that it is critical for discriminating between stimuli which have some features in common and thus it ...

The role of perirhinal cortex in visual discrimination learning for visual secondary reinforcement in rats

, 2003
Perirhinal cortex in monkeys has been thought to be involved in visual associative learning. The authors examined rats' ability to make associations between visual stimuli in a visual secondary reinforcement task.

Lesions of the perirhinal cortex do not impair integration of visual and geometric information in rats.

, 2010
Rats with lesions of the perirhinal cortex and a control group were required to find a platform in 1 corner of a white rectangle and in the reflection of this corner in a black rectangle.

Computational models of familiarity discrimination in the perirhinal cortex

, 2001
Much evidence indicates that recognition memory involves two separable processes, recollection and familiarity discrimination, with familiarity discrimination being dependent on the perirhinal cortex of the temporal lobe.
