entorhinal cortex

The inner gyrus of the temporal lobe of the brain. It comprises the parahippocampal gyrus and the subicular cortex. In the entorhinal cortex, the five-layer structure of the ventral temporal cortex gradually merges into the single layer that is found in the dentate gyrus, the innermost edge of the temporal lobe. The entorhinal cortex receives signals from and projects back to the frontal cortex, the insula, and the cingulate cortex, and it is the key brain region funneling input to the hippocampus.

In the majority of cases, tau pathology first appears in the memory centres of the brain, known as the entorhinal cortex and hippocampal formation.

Inducible tau transgenic mouse models such as FVB-Tg (tetO-Tau[sub]P301L) 4510 have been established, where tau expression is confined to the entorhinal cortex (EC) to mimic early tau pathology in AD.

Tau immunostaining demonstrated characteristic pathology of argyrophilic grains in the amygdala, entorhinal cortex, and hippocampus proper as well as scattered oligodendroglial "coiled" bodies in white matter.
A common thesis concerning the specific mechanisms involved in declarative episodic encoding is that MTL regions surrounding the hippocampus (namely the parahippocampal and entorhinal cortex) receive sensorial information from different areas of the cortex.
G-CSF receptors are expressed in pyramidal neurons in the cortex (mainly layers II/III and V), the Purkinje cell layer of the cerebellum, the hippocampus (hilus and CA3 field), the entorhinal cortex and the olfactory bulb.

Results of the OPID-20 test showed significant differences among the four groups of participants, which correlated with the thinning of two brain regions: the hippocampus and the entorhinal cortex (both of which are involved in memory), regions which have previously been linked to Alzheimer's risk.
