The polymorphic layer is often called the hilus or hilar region. [12] The neurons in the polymorphic layer, including mossy cells and GABAergic interneurons, primarily receive inputs from the granule cells in the dentate gyrus in the form of mossy fibers and project to the inner molecular layer of the dentate gyrus via the associational ...
Neuroimaging pictures can show a number of different shapes, depending on the angle and location of the cut. Shape of human hippocampus and associated structures Topologically, the surface of a cerebral hemisphere can be regarded as a sphere with an indentation where it attaches to the midbrain.
In 1825, Bouchet and Cazauvieilh described palpable firmness and atrophy of the uncus and medial temporal lobe of brains from epileptic and non-epileptic individuals. [4]: 565 In 1880, Wilhelm Sommer investigated 90 brains and described the classical Ammon's horn sclerosis pattern, severe neuronal cell loss in hippocampal subfield cornum Ammonis 1 (CA1) and some neuronal cell loss in ...

The intermediate hippocampus has overlapping characteristics with both the ventral and dorsal hippocampus. [30] Using anterograde tracing methods, Cenquizca and Swanson (2007) located the moderate projections to two primary olfactory cortical areas and prelimbic areas of the medial prefrontal cortex. This region has the smallest number of place ...
The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, containing the cerebral cortex (of the two cerebral hemispheres) as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.
"A tumor can also block the normal flow of activity in the brain or signaling to and from the brain.” Elijah was airlifted to Primary Children’s Hospital in Salt Lake City, where he underwent ...
Polymicrogyria (PMG) is a condition that affects the development of the human brain by multiple small gyri creating excessive folding of the brain leading to an abnormally thick cortex. This abnormality can affect either one region of the brain or multiple regions.
