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 hippocampus plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. In humans, and other primates the hippocampus is located in the archicortex , one of the three regions of allocortex , in each hemisphere with neural projections to the neocortex .
Unlike the hippocampus which is involved in the encoding of complex memories, the cerebellum plays a role in the learning of procedural memory, and motor learning, such as skills requiring co-ordination and fine motor control. [4]
The hippocampus is important for explicit memory. The hippocampus is also important for memory consolidation. The hippocampus receives input from different parts of the cortex and sends its output out to different parts of the brain also. The input comes from secondary and tertiary sensory areas that have processed the information a lot already.
The dentate gyrus is thought to contribute to the formation of memories, and to play a role in depression. The role of the hippocampus in learning and memory has been studied for many decades particularly since the late 1950s, following the results of surgery, in an American male, to remove most of the hippocampus.

Typically, the hippocampal formation is said to included the dentate gyrus, the hippocampus, and the subiculum. [2] The presubiculum, parasubiculum, and the entorhinal cortex may also be included. [3] The hippocampal formation is thought to play a role in memory, spatial navigation and control of attention.
CA3 has been implicated in a number of working theories on memory and hippocampal learning processes. Slow oscillatory rhythms (theta-band; 3–8 Hz) are cholinergically driven patterns that depend on coupling of interneurons and pyramidal cell axons via gap junctions, as well as glutaminergic (excitatory) and GABAergic (inhibitory) synapses.
Howard B. Eichenbaum (October 16, 1947 – July 21, 2017) was an American psychologist and neuroscientist who studied the hippocampus. [1] [2] He was a university professor and director of the Center for Memory and Brain at Boston University, having previously worked at Wellesley College. He was the editor-in-chief of the scientific journal ...
