Integration of Synaptic Events: - temporal summation : postsynaptic neuron stimulated by the same terminal in rapid succession - spatial summation : postsynaptic neuron stimulated by multiple terminals at the same time - synaptic potentiation: continuous use of synapse enhances presynaptic neuron's ability to excite postsynaptic neuron - presynaptic inhibition: release of excitatory neurotransmitter is inhibited by activity of another neuron via axoaxonic synapse Neurotransmitters: - acetylcholine (ACh) - released at neuromuscular junctions throughout nervous system (excitatory for skeletal muscle; inhibitory for cardiac muscle; also used in o Alzheimer disease is due to loss of neurons that use ACh as neurotransmitter - biogenic amines : catecholamines ( dopamine , epinephrine & norepinephrine indolamines ( histamine & serotonin )... o biogenic amines are synthesized from amino acids (catecholamines from tyrosine ; serotonin from tryptophan ; histamine from histidine ) o norepinephrine
