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
Effects of long-term benzodiazepine use including sustained attention, verbal learning and memory and psychomotor, visuo-motor and visuo-conceptual abilities. These effects on cognition exist, although their impact on a patient's daily functioning is, in most (but not all cases), insignificant. Transient changes in the brain have been found using neuroimaging studies, but no brain abnormalities have been found in patients treated long term with benzodiazepines. When benzodiazepine users cease long-term benzodiazepine therapy, their cognitive function improves in the first six months, although deficits may be permanent or take longer than six months to return to baseline. In the elderly, long-term benzodiazepine therapy is a risk factor
