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
Long-term potentiation the rabbit hippocampus. Bliss and Tony Gardner-Medwin published a similar report of long-lasting potentiation in the awake animal which appeared in the same issue as the Bliss and Lømo report. In 1975, Douglas and Goddard proposed "long-term potentiation" as a new name for the phenomenon of long-lasting potentiation. Andersen suggested that the authors chose "long-term potentiation" perhaps because of its easily pronounced acronym, "LTP". The physical and biological mechanism of LTP is still not understood, but some successful models have been developed.
