Perirhinal cortex hyperexcitability in pilocarpine‐treated epileptic rats [PDF]

Hippocampus, 2011
AbstractThe perirhinal cortex (PC), which is heavily connected with several epileptogenic regions of the limbic system such as the entorhinal cortex and amygdala, is involved in the generation and spread of seizures. However, the functional alterations occurring within an epileptic PC network are unknown.

Regional Functional Molecular Profiles Within the Mammalian Cortex: A Commentary on Limbic Mesocortex

Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.
Two lateral mouse brain sagittal sections labeled, respectively, for Lypd1 (A) and Kcnab3 (B). (A) Lypd1 labels positively cortical Layers 2 and 5 (less heavily), but only at limbic mesocortical sites, forming the limbic ring that separates the unlabeled isocortex (IsoCx) from the unlabeled hippocampal and olfactory allocortex (Hi, Sub, ERh; OlfCx ...

Reduced ictogenic potential of 4-aminopyridine in the perirhinal and entorhinal cortex of kainate-treated chronic epileptic rats

Neurobiology of Disease, 2008
We investigated the potential of 4-AP (50–100 μM) to induce seizure-like events (SLEs) in combined entorhinal cortex–hippocampal slices from Sprague Dawley rats which developed spontaneous limbic seizures following kainic acid induced status epilepticus.

External Source Monitoring and Reality Monitoring: Meta‐Analysis of fMRI Studies

Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.
We conducted an fMRI meta‐analysis showing the overlapping and unique clusters involved in external source monitoring and reality monitoring. Our results show the peculiarities of each monitoring task better defining each process. ABSTRACT Being able to remember the origin of a particular memory is for times even more important than the memory itself ...

The role of the human entorhinal cortex in a representational account of memory

Frontiers in Human Neuroscience, 2015
Connectivity studies in animals form the basis for a representational view of medial temporal lobe (MTL) subregions. In this view, distinct subfields of the entorhinal cortex (EC) relay object-related and spatial information from the perirhinal and ...

Fibronectin1‐Expressing Subicular Circuits Selectively Govern the Retrieval of Novel Object Recognition

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Fibronectin 1 (FN1)‐expressing subicular subpopulations encode novel object preference and selectively govern retrieval of novel object recognition (NOR) via affecting excitability of entorhinal‐projecting circuit through large conductance Ca2+‐activated potassium (BK) channel. ABSTRACT Novel object recognition (NOR), referring to the cognitive ability

Sex differences in activations to the sight of faces, scenes, body parts and tools in visual and non-visual cortical regions leading to the human hippocampus

Biology of Sex Differences
In a large Human Connectome Project dataset of 504 females and 452 males performing a 0-back memory task with visual images using the HCP-MultiModalParcellation, faces activated some key cortical regions more (using FDR correction) in females than males,

A computational model of basal ganglia and its role in memory retrieval in rewarded visual memory tasks

Frontiers in Computational Neuroscience, 2010
Visual working memory tasks involve a network of cortical areas such as inferotemporal, medial temporal and prefrontal cortices. We suggest here to investigate the role of the basal ganglia in the learning of delayed rewarded tasks through the selective ...

Neural and Navigational Features Influencing the Novelty Induced Benefits on Episodic Memory

Hippocampus, Volume 36, Issue 4, July 2026.
ABSTRACT Studies in animals have robustly shown that exposure to novelty can promote memory for information presented in the temporal vicinity. In humans, however, evidence for such novelty‐related memory benefits has been mixed. In this EEG study, we investigated the neurobiological mechanisms underlying effects of novelty on memory and whether ...

β-Adrenoceptors and synaptic plasticity in the perirhinal cortex

Neuroscience, 2014
Experiences with a high degree of emotional salience are better remembered than events that have little emotional context and the amygdala is thought to play an important role in this enhancement of memory. Visual recognition memory relies on synaptic plasticity in the perirhinal cortex but little is known about the mechanisms that may underlie ...
