The entorhinal region is an outstanding, differentiated “association center” within the allocortex.1 It is intimately connected with the hippocampus
by way of the perforant pathway. It thus forms, together with the hippocampus, a multineuronal regulatory circuit at the center of the limbic system. Signals arriving in the entorhinal cortex proceed to the hippocampus, Inhibitors,research,lifescience,medical pass through sellectchem several synapses, and return, in part, to the entorhinal cortex. This regulatory circuit, seems to be of major importance for the storage of orientation and also for memory.2 Studies in primates have Inhibitors,research,lifescience,medical shown that primary cortical fields and all secondary cortical fields with visual, auditory, and somatosensory functions have reciprocal connections with the entorhinal cortex, either directly or by way of the perirhinal area.3-5 The multisensory areas in caudal
portions of the orbitofrontal region, and the rostral and ventral fields of the claustrocortex, project mainly onto the rostral Inhibitors,research,lifescience,medical fields of the entorhinal area (Figure 1) 6 Furthermore, as extensive studies in the cat. have shown, there are well-developed systems of both longitudinal and transverse connections that, enable the activity of systems within the entorhinal cortex to be integrated with the complex of afferent, information. Sensory afferent, information is delivered Inhibitors,research,lifescience,medical to the hippocampus by way of the upper layers of the perirhinal area and the entorhinal cortex. Efferent projections arise from the lower layers of the perirhinal and entorhinal areas. The entorhinal cortex thus integrates information from all sensory modalities from both the interior Inhibitors,research,lifescience,medical and the exterior of the organism.7-10 Figure 1.

The perirhinal area, which is also called the transentorhinal subregion,1 lies between the lateral part of the entorhinal cortex and the isocortex of the temporal lobe.11 It, displays the full array of cortical layers in a coronal section passing through the central portion of the amygdala, in the entorhinal central medial and lateral area (and the interpolar medial area); it is most, highly differentiated in the central lateral area.
