Plasticity of glutamate synaptic mechanisms

Enhanced glutamate synaptic transmission may be expected to alter the balance of excitation and inhibition in brain, leading to seizures. Several differences between epileptic and nonepileptic brains in presynaptic and postsynaptic glutamate mechanisms have been reported. These findings suggest that altered glutamate mechanisms contribute to the hyperexcitability of epileptic brain.
