This allows researchers to quantify anatomical features of the brain in terms of shape, mass, volume (e.g. of the hippocampus, or of the primary versus secondary visual cortex), and to derive more specific information, such as the encephalization quotient, grey matter density and white matter connectivity, gyrification, cortical thickness, or ...
The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus.Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum.
The hippocampus is a five centimetre long ridge of gray matter tissue within the parahippocampal gyrus that can only be seen when the gyrus is opened up. [ 19 ] [ 20 ] The hippocampus is an inward fold of three-layered archicortex (one of three regions of the allocortex ) into the medial temporal lobe of the brain, where it elevates into the ...
Hippocampus and associated structures; Fornix and septal nuclei; Subcortical areas: Septal nuclei; Amygdala; Nucleus accumbens; Diencephalic structures: Hypothalamus; Mammillary bodies; Anterior nuclei of thalamus; Other areas that have been included in the limbic system include the: Stria medullaris; Central gray and dorsal and ventral nuclei ...
The cerebrum is made up of the two cerebral hemispheres and their cerebral cortices (the outer layers of grey matter), and the underlying regions of white matter. [2] Its subcortical structures include the hippocampus, basal ganglia and olfactory bulb.
The parahippocampal gyrus (or hippocampal gyrus [1]) 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. [2] Asymmetry has been observed in schizophrenia. [3]
Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of the brain. It has a distinctive, curved shape that has been likened to the sea-horse monster of Greek mythology and the ram's horns of Amun in Egyptian mythology .
The dentate gyrus (DG) is one of the subfields of the hippocampus, in the hippocampal formation.The hippocampal formation is located in the temporal lobe of the brain, and includes the hippocampus (including CA1 to CA4) subfields, and other subfields including the dentate gyrus, subiculum, and presubiculum.
