Perirhinal Cortex Neuronal Activity is Actively Related to Working Memory in the Macaque

open access: yesNeural Plasticity, 2002
Lesion studies suggest that the perirhinai cortex plays a role in object recognition memory. To analyze its role, we recorded the activity of single neurons in the perirhinal cortex in a rhesus monkey (Macaca mulatta) performing a delayed matching-to ...

The Perirhinal Cortex and Long-Term Familiarity Memory [PDF]

open access: yesThe 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, as

Effects of the Bee Venom Herbal Acupuncture on the Neurotransmitters of the Rat Brain Cortex

open access: yesJournal of Pharmacopuncture, 2001
In order to study the effects of bee venom Herbal Acupuncture on neurotransmitters in the rat brain cortex, herbal acupuncture with bee venom group and normal saline group was performed at LI4 bilaterally of the rat.

Integrative and distinctive coding of visual and conceptual object features in the ventral visual stream

open access: yeseLife, 2018
A significant body of research in cognitive neuroscience is aimed at understanding how object concepts are represented in the human brain. However, it remains unknown whether and where the visual and abstract conceptual features that define an object ...

Posterior white matter hyperintensities are associated with reduced medial temporal lobe subregional integrity and long-term memory in older adults

open access: yesNeuroImage: Clinical, 2023
White matter hyperintensities are a marker of small vessel cerebrovascular disease that are strongly related to cognition in older adults. Similarly, medial temporal lobe atrophy is well-documented in aging and Alzheimer’s disease and is associated with ...

Hippocampal Seizure‐Related Burden is Associated with Accelerated Long‐Term Forgetting in Focal Epilepsy

open access: yesAnnals of Neurology, EarlyView.
Objective Memory impairment is a frequent comorbidity of focal epilepsy, incompletely explained by seizure frequency or structural pathology. Ictal and postictal hippocampal dysfunction disrupt memory processes, but their cumulative impact remains poorly quantified.

Pathological hippocampal–cortical hypersynchronization disrupts memory in temporal lobe epilepsy: A multimodal intracranial electroencephalographic–functional magnetic resonance imaging study

open access: yesEpilepsia, EarlyView.
Abstract Objective Memory impairment is a common comorbidity in temporal lobe epilepsy (TLE) and is thought to arise from hippocampal dysfunction and disrupted interactions within a distributed memory network involving medial temporal, frontal, and parietal cortical regions.

Binding crossmodal object features in perirhinal cortex [PDF]

open access: yesProceedings 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 ...

Network Plasticity Involved in the Spread of Neural Activity Within the Rhinal Cortices as Revealed by Voltage-Sensitive Dye Imaging in Mouse Brain Slices

open access: yesFrontiers in Cellular Neuroscience, 2019
The rhinal cortices, such as the perirhinal cortex (PC) and the entorhinal cortex (EC), are located within the bidirectional pathway between the neocortex and the hippocampus. Physiological studies indicate that the perirhinal transmission of neocortical
