Hippocampus anatomy 22d
The subiculum connects with the parahippocampal gyrus, a region of the cerebral cortex that surrounds the hippocampus. Ammon's horn is continuous with the subiculum, which acts as the main output source of the hippocampal formation. v hiduiTq1ei8 Hippocampus The name derives from its curved shape in coronal sections of the brain, which resembles a seahorse (Greek. It is divided into three fields (CA1, CA2, and CA3) that process, send, and receive input from other brain regions. Ammon's horn is another name for the hippocampus major or hippocampus proper. The hippocampus proper consists of three major subfields (CA1-CA3). The hippocampal formation is a prominent C-shaped structure bulging in the floor of the temporal horn of the lateral ventricle. This elegant study reported that recollection decays before. The hippocampus is one of several brain regions that together comprise the hippocampal formation. Neurogenesis (new neuron formation) in the adult brain occurs in the dentate gyrus, which receives input from other brain areas and aids in new memory formation, learning, and spacial memory. The hippocampus supports both the recollection and the familiarity components of recognition memory. Noncanonical projections to the hippocampal CA3 regulate spatial learning and memory by modulating the feedforward hippocampal trisynaptic pathway.
The dentate gyrus is folded and nestled within the hippocampal sulcus (brain indentation). The two gyri, the dentate gyrus and Ammon's horn (cornu ammonis), form interlocking connections with one another. The hippocampus is the main structure of the hippocampal formation, which is composed of two gyri (brain folds) and the subiculum.
