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 ...
In place cells, a type of neuron found in the hippocampal region of the brain, phase precession is believed to play a major role in the neural coding of information. John O'Keefe , who later shared the 2014 Nobel Prize in Physiology or Medicine for his discovery that place cells help form a "map" of the body's position in space, co-discovered ...
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]
The findings ultimately supported the cognitive map theory, the idea that the hippocampus hold a spatial representation, a cognitive map of the environment. [10] There has been much debate as to whether hippocampal place cells function depends on landmarks in the environment, on environmental boundaries, or on an interaction between the two. [11]
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 the components of the hippocampal formation located in the limbic system.
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.
Phase-of-firing code is a neural coding scheme that combines the spike count code with a time reference based on oscillations. This type of code takes into account a time label for each spike according to a time reference based on phase of local ongoing oscillations at low [ 39 ] or high frequencies.
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.
