Hippocampus, 1995
AbstractThe pattern of impulse transfer along the entorhinal‐hippocampal‐entorhinal loop has been analyzed in the guinea pig by field potential analysis. The loop was driven by impulse volleys conducted by presubicular commissural fibers, directly stimulated in the dorsal psalterium, which monosynaptically activated perforant path neurons in the medial

Decreased entorhinal cortex volumes in schizophrenia
Schizophrenia Research, 2008The 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

Persistent activity and memory in the entorhinal cortex
Trends in Neurosciences, 2003The 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.

Spatial representation and the architecture of the entorhinal cortex
Trends in Neurosciences, 2006It 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.

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 of the mouse: Cytoarchitectonical organization
Hippocampus, 2001AbstractThe 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

Microstructure of a spatial map in the entorhinal cortex
Nature, 2005The 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

Entorhinal cortex pathology in Alzheimer's disease
Hippocampus, 1991AbstractThe 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 ...

Entorhinal cortex (EC) has recently gained increased interest following the findings of grid cells (Fyhn et al., 2004; Hafting et al., 2005). It has also recently been shown that place cells, intensely studied in the hippocampus, exist upstream of hippocampus in superficial layers of entorhinal cortex (Fyhn et al., 2004). In the light of these findings,

Representation of Geometric Borders in the Entorhinal Cortex
Science, 2008We report the existence of an entorhinal cell type that fires when an animal is close to the borders of the proximal environment. The orientation-specific edge-apposing activity of these “border cells” is maintained when the environment is stretched and during testing in enclosures of different size and shape in different rooms.
