The amino acid glutamate is a neurotransmitter in the hippocampus with an excitatory function. The excitatory function involves memory and is present at all times as we are constantly forming memories. Alcohol inhibits the stimulation of the receptor by glutamate.
Neurons respond to low levels of stimulation by putting more receptors in place.
When alcohol is withdrawn the receptors remain and are now bound by glutimate. Calcium ions flood into theneurons causing the brain cell to commit suicide by distruction of the cell memebrane.
