Entorhinal cortex modules of the human brain

The Journal of Comparative Neurology, 1996
Much is known about modular organization in the cerebral cortex, but this knowledge is skewed markedly toward primary sensory areas, and in fact, it has been difficult to demonstrate elsewhere. In this report, we test the hypothesis that a unique form of modules exists in the entorhinal area of the human cortex (Brodmann's area 28).

The Entorhinal Cortex

Abstract This chapter begins with an historical overview of the definition of the entorhinal cortex, its relationship with the hippocampus, and why a separate chapter is deemed relevant. Subsequent sections review the neurostructural and connectional organization of the entorhinal cortex.

Entorhinal cortex and consolidated memory

Neuroscience Research, 2014
The entorhinal cortex is thought to support rapid encoding of new associations by serving as an interface between the hippocampus and neocortical regions. Although the entorhinal-hippocampal interaction is undoubtedly essential for initial memory acquisition, the entorhinal cortex contributes to memory retrieval even after the hippocampus is no longer ...

Persistent activity and memory in the entorhinal cortex

Trends in Neurosciences, 2003
The entorhinal cortex (EC) is an essential component of the medial temporal lobe long-term-memory system. Recently, Egorov et al. demonstrated that neurons in layer 5 of the EC show graded persistent activity: each neuron could maintain a constant rate firing over several minutes, even in the absence of input from other neurons.

Microstructure of a spatial map in the entorhinal cortex

Nature, 2005
The ability to find one's way depends on neural algorithms that integrate information about place, distance and direction, but the implementation of these operations in cortical microcircuits is poorly understood. Here we show that the dorsocaudal medial entorhinal cortex (dMEC) contains a directionally oriented, topographically organized neural map of

Decreased entorhinal cortex volumes in schizophrenia

Schizophrenia Research, 2008
The entorhinal cortex is located in the medial temporal lobe and is involved in memory and learning. Previous MRI studies reported conflicting findings in schizophrenia, showing normal or reduced entorhinal size.To explore entorhinal cortex volumes in a large sample of patients with schizophrenia recruited from the geographically defined catchment area

The Dopaminergic Innervation of Monkey Entorhinal Cortex

Cerebral Cortex, 1993
Dopamine has been implicated in the pathophysiology of schizophrenia, and the entorhinal cortex (ERC) is thought to be a site of structural pathology in this disorder. However, relatively little is known about the dopaminergic (DA) innervation of ERC in the primate brain.

Entorhinal cortex of the mouse: Cytoarchitectonical organization

Hippocampus, 2001
AbstractThe present study describes the cytoarchitectonical and chemoarchitectonical organization of the entorhinal cortex of the mouse (C57BL/6J strain). The entorhinal cortex is medially bordered by the parasubiculum, and laterally by the perirhinal cortex; rostrally and medially it is bordered by the piriform cortex, whereas caudally and dorsally it

Spatial representation and the architecture of the entorhinal cortex

Trends in Neurosciences, 2006
It has recently been recognized that the entorhinal cortex has a crucial role in spatial representation and navigation. How the position of an animal is computed within the entorhinal circuitry remains to be determined, but the architectural organization of this brain area might provide some clues.

Entorhinal cortex pathology in Alzheimer's disease

Hippocampus, 1991
AbstractThe anatomical distribution of pathological changes in Alzheimer's disease, although highly selective for only certain brain areas, can be widespread at the endstage of the illness and can affect many neural systems. Propriety for onset among these is a question of importance for clues to the etiology of the disease, but one that is formidable ...
