What does the entorhinal cortex do?
The entorhinal cortex is the gateway for information entering and leaving the hippocampal formation. The entorhinal cortex is a component of the medial temporal lobe memory system, although it is increasingly believed to have a perceptual function (Baxter, 2009; Suzuki, 2009).
What does the parahippocampal cortex do?
The parahippocampal gyrus (or hippocampal gyrus) is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. The region plays an important role in memory encoding and retrieval. It has been involved in some cases of hippocampal sclerosis.
What disease does the entorhinal cortex help show?
The entorhinal cortex is the first area of the brain to be affected in Alzheimer’s disease; a recent functional magnetic resonance imaging study has localised the area to the lateral entorhinal cortex.
What is perirhinal cortex?
The perirhinal cortex is a proisocortical area in the medial temporal lobe interconnecting the hippocampal formation together with other parts of the limbic lobe and with the lateral temporal and occipitotemporal association cortices.
What does entorhinal mean?
: of, relating to, or being the part of the cerebral cortex in the medial temporal lobe that serves as the main cortical input to the hippocampus.
What happens when the entorhinal cortex is damaged?
Damage to the entorhinal cortex is common in patients who experience traumatic brain injury, stroke, and Alzheimer’s disease. Entorhinal damage is assumed to interfere with sensory integration; however, substantive knowledge of behavioral patterns is lacking.
Is the entorhinal cortex in the limbic system?
The limbic system includes the hippocampal formation, amygdala, septal nuclei, cingulate cortex, entorhinal cortex, perirhinal cortex, and parahippocampal cortex. These last three cortical areas comprise different portions of the temporal lobe.
Is entorhinal cortex part of parahippocampal gyrus?
The parahippocampal gyrus is made up of several cortical areas, including the primary olfactory cortex at the anterior pole and the entorhinal cortex just posterior to the anterior pole (Van Hoesen, 1982).
Is the entorhinal cortex the same as parahippocampal gyrus?
The entorhinal (brown) and perirhinal (yellow) cortices form the medial and lateral components, respectively, of the anterior portion of the parahip- pocampal gyrus, while the parahippocampal cortex (off-white) forms the posterior portion.
What can happen if the entorhinal cortex is damaged?
What does Perirhinal mean?
perirhinal – near the nose.
