Amygdala input promotes spread of excitatory neural activity from perirhinal cortex to the entorhinal-hippocampal circuit.
A number of sensory modalities most likely converge in the rat perirhinal cortex. The perirhinal cortex also interconnects with the amygdala, which plays an important role in various motivational and emotional behaviors. The neural pathway from the perirhinal cortex to the entorhinal cortex is considered one of the main paths into the entorhinal-hippocampal network, which has a crucial role in ...
متن کاملمدل شبکه ی عصبی از نگاشت سلول‌های شبکه به سلول‌های مکانی
Abstract: Medial entorhinal cortex is known to be the hub of a brain system for navigation and spatial representation. These cells increase firing frequency at multiple regions in the environment, arranged in regular triangular grids. Each cell has some properties including spacing, orientation, and phase shift of the nodes of its grid. Entorhinal cortex is commonly perceived to be the major in...
متن کاملHippocampal and subicular efferents and afferents of the perirhinal, postrhinal, and entorhinal cortices of the rat.
Available evidence suggests there is functional differentiation among hippocampal and parahippocampal subregions and along the dorsoventral (septotemporal) axis of the hippocampus. The aim of this study was to characterize and compare the efferent and afferent connections of perirhinal areas 35 and 36, postrhinal cortex, and the lateral and medial entorhinal areas (LEA and MEA) with dorsal and ...

Introduction & Objective: In the CNS, adenosine is known to suppress repetitive neuronal Firing, suggesting a role as an endogenous modifier of seizures. Indeed, intracerebral adenosine concentrations rise acutely during seizure activity and are thought to be responsible for terminating seizures and establishing a period of post-ictal refractoriness. However, it is unclear whether this suppre...
متن کاملThe effect of Gallic acid on prenatal entorhinal cortex and CA1/CA3 hippocampal areas in trimethyltin intoxication rat
Background: Prenatal intoxication with trimethyletin (TMT) induces widespread neuronal death in the central nervous system by inducing oxidative stress. The aim of this study was to evaluate the antioxidant effect of gallic acid (GA) on the neuronal density of the entorhinal cortex, hippocampal pyramidal cells and oxidative stress parameters in the fetal forebrain following TMT intoxication. ...
