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
Prenatal memory the neurotoxic effects (harm to nerve cells) of prenatal methamphetamine exposure on brain development, as well as on cognitive functioning. Children exposed to meth in utero scored lower on key measures of memory performance, including attention, verbal memory and long term spatial memory. The reduced size of brain structures associated with memory and attention was also noted through magnetic resonance imaging (MRI), a process used to produce images of the brain for observation. For example, those with prenantal meth exposure had, on average, a smaller hippocampus (a brain structure involved in many things, including memory) than control participants. This reduction
