Neuroanatomy of memory Neuroanatomy of memory The neuroanatomy of memory encompasses a wide variety of anatomical structures in 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. There is evidence that the hippocampus contains cognitive maps in humans. In one study, single-cell recordings were taken from electrodes implanted in a rat's hippocampus, and it was found that certain neurons
Early long-term potentiation which reflects their deficit in late phase LTP. Training of simple reflexes in Aplysia has shown a strengthening between sensory and motor neurons responsible for those reflexes; on a cellular level, for short-term memory (and thus, early LTP) potentiation leads to an increase in presynaptic neurotransmitter by means of modifications of proteins through cAMP-dependent PKA and PKC. The long-term process requires new protein synthesis and CAMP-mediated gene expression, and results in the growth of new synaptic connections. These findings have led to the question whether there is a similar process in mammals. Input to the hippocampus comes from the neurons
