Involvement of human amygdala and orbitofrontal cortex in hunger-enhanced memory for food stimuli [PDF]

, 2001
We used positron emission tomography to measure regional cerebral blood flow (rCBF) in 10 healthy volunteers performing a recognition memory task with food and non-food items.

Experience transforms crossmodal object representations in the anterior temporal lobes

eLife
Combining information from multiple senses is essential to object recognition, core to the ability to learn concepts, make new inferences, and generalize across distinct entities.

5-HT2a receptor in mPFC influences context-guided reconsolidation of object memory in perirhinal cortex

eLife, 2018
Context-dependent memories may guide adaptive behavior relaying in previous experience while updating stored information through reconsolidation. Retrieval can be triggered by partial and shared cues.

Elevated tau in the piriform cortex in Alzheimer's but not Parkinson's disease using PET‐MR

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION Olfactory dysfunction can be an early sign of Alzheimer's disease (AD). We used tau positron emission tomography‐magnetic resonance (PET‐MR) to analyze a key region of the olfactory circuit, the piriform cortex, in comparison to the adjacent

Perirhinal cortex and place-object conditional learning in the rat

, 2001
The present study examined whether excitotoxic lesions of the perirhinal cortex can affect acquisition of a place–object conditional task in which object and spatial information must be integrated. Testing was carried-out in a double Y-maze apparatus, in

Direction- and distance-dependent interareal connectivity of pyramidal cell subpopulations in the rat frontal cortex

Frontiers in Neural Circuits, 2013
The frontal cortex plays an important role in the initiation and execution of movements via widespread projections to various cortical and subcortical areas.

Topographic organization of the reciprocal connections between the monkey entorhinal cortex and the perirhinal and parahippocampal cortices

, 1994
The perirhinal and parahippocampal cortices constitute the major sources of cortical input to the monkey entorhinal cortex. Neuropsychological studies have shown that these three cortical regions contribute in an important way to normal memory function ...

Characterization of auditory synaptic inputs to gerbil perirhinal cortex

Frontiers in Neural Circuits, 2015
The representation of acoustic cues involves regions downstream from the auditory cortex (ACx). One such area, the perirhinal cortex (PRh), processes sensory signals containing mnemonic information.

Capacity of perirhinal cortex network for recognising frequently repeating stimuli

, 2002
Much evidence indicates that discrimination of the familiarity of visual stimuli is dependent on the perirhinal cortex of the temporal lobe. A stimulus can become familiar to animals or humans either when a stimulus is seen once but is behaviourally ...
