The hippocampus is a brain structure consisting of a dense layer of neurons at the mesial surface of the temporal lobe. It is part of the limbic system and has been shown to be essential for the consolidation of long-term memory. There is ample evidence of a link between MRI hippocampal volume and memory (1), and in broader sense - cognitive performance (2). The hippocampus projections reach limbic structures - prefrontal cortex, amygdala and accumbens nuclei to then form the Papez circuit, essential for emotional response. The hippocampus connectivity patterns and central position in a number of functional networks explain its involvement in psychiatric disorders - depression and schizophrenia(3). Its specific vulnerability to lack of oxygen and neurodegeneration has made it one of the most extensively studied structures in the human central nervous system. Hippocampal damage has been linked to several neuropsychiatric disorders - Alzheimer’s disease, epilepsy, drug abuse, depression and schizophrenia, to name but a few. Each of these is related to structural changes in hippocampal anatomy. The study of alcohol use makes particular sense as some of the symptoms of chronic alcoholism affect functions attributed to the hippocampus, particularly emotional/motivational and cognitive functions, which are known to be modulated by the hippocampus (4).
