Differential medial temporal lobe morphometric predictors of item- and relational-encoded memories in healthy individuals and in individuals with mild cognitive impairment and Alzheimer's disease. [PDF]
, 2017 INTRODUCTION:Episodic memory processes are supported by different subregions of the medial temporal lobe (MTL). In contrast to a unitary model of memory recognition supported solely by the hippocampus, a current model suggests that item encoding engages ...

Dynamics of Hippocampal and Cortical Activation during Consolidation of a Nonspatial Memory [PDF]
, 2006 Observations of temporally graded retrograde amnesia after hippocampal damage suggest that the hippocampal region plays a critical, time-limited role in memory consolidation.

Why is there a special issue on perirhinal cortex in a journal called hippocampus? The perirhinal cortex in historical perspective [PDF]
Hippocampus, 2012 AbstractDespite its small size, the perirhinal cortex (PRh) plays a central role in understanding the cerebral cortex, vision, and memory; it figures in discussions of cognitive capacities as diverse as object perception, semantic knowledge, feelings of familiarity, and conscious recollection. Two conceptual constructs have encompassed PRh. The current

The piriform, perirhinal, and entorhinal cortex in seizure generation [PDF]
Frontiers in Neural Circuits, 2015 Understanding neural network behavior is essential to shed light on epileptogenesis and seizure propagation. The interconnectivity and plasticity of mammalian limbic and neocortical brain regions provide the substrate for the hypersynchrony and hyperexcitability associated with seizure activity.

Distinct Resting-State Connectomes for Face and Scene Perception Predict Individual Task Performance. [PDF]
Hum Brain MappResting‐state fMRI and MEG functional connectivity reveal that the FFA and PPA anchor distinct spatio‐temporal networks. The strength of this intrinsic architecture shows a double dissociation: FFA‐network connectivity specifically predicts face‐task performance, while PPA‐network connectivity predicts scene‐task performance, linking intrinsic ...

Déjà vu and the entorhinal cortex: dissociating recollective from familiarity disruptions in a single case patient [PDF]
, 2018 Past research has demonstrated a relationship between déjà vu and the entorhinal cortex in patients with wider medial temporal lobe damage. The aim of the present research was to investigate this crucial link in a patient (MR) with a selective lesion to ...

The Perirhinal Cortex and Long-Term Familiarity Memory [PDF]
The Quarterly Journal of Experimental Psychology Section B, 2005 To analyse the functions of the perirhinal cortex, the activity of single neurons in the perirhinal cortex was recorded while macaques performed a delayed matching-to-sample task with up to three intervening stimuli. Some neurons had activity related to working memory, in that they responded more to the sample than to the match image within a trial ...

5-HT2a receptor in mPFC influences context-guided reconsolidation of object memory in perirhinal cortex [PDF]
, 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.

Binding crossmodal object features in perirhinal cortex [PDF]
Proceedings of the National Academy of Sciences, 2006 Knowledge of objects in the world is stored in our brains as rich, multimodal representations. Because the neural pathways that process this diverse sensory information are largely anatomically distinct, a fundamental challenge to cognitive neuroscience is to explain how the brain binds the different sensory features that comprise an object to form ...

International Veterinary Epilepsy Task Force recommendations for systematic sampling and processing of brains from epileptic dogs and cats [PDF]
, 2015 Traditionally, histological investigations of the epileptic brain are required to identify epileptogenic brain lesions, to evaluate the impact of seizure activity, to search for mechanisms of drug-resistance and to look for comorbidities.
