- Why does amplitude decrease in a train of action potentialJane is wishing to artificially stimulate neurotransmitter release by a motor neuron. She should be able to do this by electrically activating the neuron (TRUE or FALSE) and/or by injecting potassium ions into the synaptic terminal/knob region (TRUE or FALSE).What triggers neurotransmitter release at the synaptic cleft?
