potential. EXCITATORY POSTSYNAPTIC POTENTIAL (EPSP) – A change in local potential occurring at the synapse which depolarizes the postsynaptic membrane and works towards producing an action potential in the postsynaptic cell. FOREBRAIN – The largest division of the brain which includes the cerebral cortex* and the basal ganglia*. It is implicated in the higher brain functions. FREE RADICALS – Atoms or groups of atoms with unpaired electron which display extraordinary activity in their interactions with matter. They have damaging effects on living cells and appear to be implicated in the mechanisms of neurodegeneration. FRONTAL LOBE – One of the four divisions (parietal, temporal, occipital) of each hemisphere of the cerebral cortex. It plays a role in controlling movement and associating the functions of other cortical areas. GABA – see GAMMA-AMINO BUTYRIC ACID
