The hippocampal formation is a compound structure in the medial temporal lobe of the brain. It forms a c-shaped bulge on the floor of the inferior horn of the lateral ventricle . [ 1 ] Typically, the hippocampal formation is said to included the dentate gyrus , the hippocampus , and the subiculum . [ 2 ]
Food caching behavior reaches a maximum in August, continues through the winter and declines in the spring. They showed that the amount of neurons added to the hippocampus was also at a max during August and winter, and declined into the spring. Using selective hippocampal lesions, cause-effect relationships were shown.
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are components of the hippocampal formation located in the limbic system.
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.
The entorhinal cortex (EC) is a major part of the hippocampal formation of the brain, and is reciprocally connected with the hippocampus. [1]The hippocampal formation, which consists of the hippocampus, perirhinal cortex, the dentate gyrus, the subicular areas and the EC forms one of the most important parts of the limbic system.
The hippocampus is located in the medial temporal lobe (subcortical), and is an infolding of the medial temporal cortex. [1] The hippocampus plays an important role in the transfer of information from short-term memory to long-term memory during encoding and retrieval stages. These stages do not need to occur successively, but are, as studies ...
The specific function of the hippocampus, coupled with seasonal changes in their volume, point towards their temporary advantages for spatial memory consolidation. Taken all together, adult neurogenesis in the hippocampus of black-capped chickadees suggest a selective mechanisms for neuronal survival in direct correlation with seasonal food ...
Neural progenitors that become hippocampal principal neurons (pyramidal and granular cells) arise from the ventricular zone of the lateral ventricle.In contrast to neural proliferation that leads to cortical formation, hippocampal precursors are produced directly in the ventricular zone because there is no subventricular zone or outer subventricular zone adjacent to the hippocampus.
