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.
A cognitive map is a type of mental representation used by an individual to order their personal store of information about their everyday or metaphorical spatial environment, and the relationship of its component parts. The concept was introduced by Edward Tolman in 1948. [1]
Then, consolidation is where the hippocampus along with other cortical structures stabilize an object within long term memory, which strengthens over time, and is a process for which a number of theories have arisen to explain the underlying mechanism. [1] After encoding, the hippocampus is capable of going through the retrieval process.
The hippocampus. 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. [1]
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.
Such brain parts as the cerebellum, striatum, cerebral cortex, hippocampus, and amygdala are thought to play an important role in memory. For example, the hippocampus is believed to be involved in spatial and declarative memory, as well as consolidating short-term into long-term memory.
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 ...
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 ...
