WebAn excitatory postsynaptic potential (EPSP) occurs if the membrane is depolarized by the ion movement. If, on the other hand, the membrane becomes hyperpolarized when the ions move, an inhibitory postsynaptic potential (IPSP) is generated. EPSPs and IPSPs are local potentials. EPSP WebWhen the electrical potential across the synaptic cleft is positive, it is called excitation. Cholinergic neurons use the chemical acetylcholine to alter synaptic-membrane permeability. Adrenergic neurons use norepinephrine or noradrenaline. Dopamine is also an excitatory neurotransmitter.
