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 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.
Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction. [ 2 ] The limbic system is involved in lower order emotional processing of input from sensory systems and consists of the amygdala , mammillary bodies , stria medullaris , central gray and dorsal and ventral nuclei of Gudden.

The third important theory of hippocampal function relates the hippocampus to space, and spatial memory, with the idea of a cognitive map first proposed by American psychologist E.C. Tolman. This theory was followed further by O'Keefe, and in 1971, he and his student Dostrovsky discovered neurons, in the rat hippocampus that seemed to show ...
It is an integral part of the limbic system, which is involved with emotion formation and processing, [1] learning, [2] and memory. [ 3 ] [ 4 ] The combination of these three functions makes the cingulate gyrus highly influential in linking motivational outcomes to behavior (e.g. a certain action induced a positive emotional response, which ...
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.
The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system , and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn , and the Dentate gyrus , each containing different types of cells .
Moreover, many cases where structures of the Papez circuit have been damaged show changes that indicate its real function. Theta waves are used to measure activity in mainly the hippocampus but can be used to measure other brain regions as well. Strong synchronization of theta waves in the hippocampus and anterior ventral thalamus has been ...
