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
Short-term memory Miller himself stated that the figure was intended as "little more than a joke" (Miller, 1989, page 401) and that Cowan (2001) provided evidence that a more realistic figure is 4±1 units. In contrast, long-term memory can hold the information indefinitely. Short-term memory should be distinguished from working memory, which refers to structures and processes used for temporarily storing and manipulating information (see details below). The idea of the division of memory into short-term and long-term dates back to the 19th century. A classical model of memory developed in the 1960s assumed that all memories pass from a short-term to
