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 ...
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.
The hippocampus' right side is more oriented towards responding to spatial aspects, whereas the left side is associated with other context information. Also, there is evidence that experience in building extensive mental maps, such as driving a city taxi for a long time (since this requires considerable memorization of routes), can increase the ...
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 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 ...
A spatial map needs to be acquired according to a frame of reference. Because it is independent from the observer's point of view, it is based on an allocentric reference system— with an object-to-object relation. It codes configurational information, using a world-centred coding system.
Additionally, the strategy used by each rodent can be scored as random (randomly checking each hole), systematic (checking each hole in a pattern) or spatial (direct movement to the hole with the drop box). Due to the spatial nature of the Barnes maze, damage to the hippocampus leads to deficits in performance of the task. [8]
Schaffer collaterals are the axons of the neurons in the CA3 regions of the hippocampus that form synapses in the CA1 regions. The hippocampus is a part of the feedback process that sends signals to stop cortisol production. Thus, a damaged hippocampus can cause memory loss and inability of cognitive function.
