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.

Mehta's findings instead indicate that there is a third key actor in this complex dialogue, the entorhinal cortex, and that the neocortex is driving the entorhinal cortex, which in turn behaves as if it is remembering something.
Different asymmetry patterns were identified in the medial side of the brain, specifically located in the limbic system including the anterior cingulate cortex and the entorhinal cortex. Leftward lateralization was observed in the entorhinal cortex in MCI nonconverters from baseline to the last visit, as well as in the rostral anterior cingulate gyrus in converters during all visits.

The placement of the electrodes did not cause histologic damage either when the stimulation was performed for Ca1 sub-region of hippocampus, anterior nucleus of thalamus and entorhinal cortex. The anterior nucleus of thalamus DBS showed exploration times of the objects similar to that of the control group (rats to which the electrodes were implanted but these did not undergo stimulation) in the object location test.
Low scores on the University of Pennsylvania Smell Identification Test (UPSIT) are linked to a thinning of the entorhinal cortex the brain region where amyloid plaques are thought to first appear as Alzheimer's disease takes hold, reported at the Alzheimer's Association International Conference.
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.

The dentate gyrus receives afferent connections from the entorhinal cortex, which act as an input region.

Contextual information from the parietal "where" pathway enters the hippocampus through the medial entorhinal cortex (MEC), which, with the discovery of spatially selective grid and boundary cells, has been shown to depend on an animal's surroundings [29, 30].
The entorhinal cortex (EC) and postrhinal cortex (POR) were then dissected out based on the previous studies [36-38] (see Figure 1 of Liu et al.
