The main symptoms are difficulty chewing and swallowing, low muscle tone in the face and tongue, speech and language development disorders, and epilepsy. These symptoms are ...
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 ...

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 ...
