The polymorphic layer is often called the hilus or hilar region. [14] 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 ...

Hippocampus in the human brain Nissl-stained coronal section of the brain of a macaque monkey, showing hippocampal formation and subfields (circled). Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain.
Many studies later culminating in work by Papez, and MacLean, the involvement of other interacting brain regions associated with emotion was recognised. [14] The hippocampus is anatomically connected to parts of the brain that are involved with emotional behavior, including the septal area , the hypothalamic mammillary bodies , and the anterior ...
While the dentate gyrus shows LTP, it is also one of the few regions of the mammalian brain where adult neurogenesis (the formation of new neurons) takes place. Some studies hypothesize that new memories could preferentially use newly formed granule cells of the dentate gyrus, providing a potential mechanism for distinguishing multiple ...
Mossy fibers form multiple synapses with the elaborate dendritic spines of CA3 pyramidal cells in the stratum lucidum of the hippocampus. These complex spines are known as thorny excrescences. [4] [15] Thorny excrescences also cover the proximal dendrites of mossy cells in the hilus. Hilar thorny excrescences are more dense and complex than ...
View of left entorhinal cortex (red) from beneath the brain, with front of brain at top. Artist's rendering. The superficial layers – layers II and III – of EC project to the dentate gyrus and hippocampus: Layer II projects primarily to dentate gyrus and hippocampal region CA3; layer III projects primarily to hippocampal region CA1 and the subiculum.
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
