Quizplus · Accepted Answer

This statement is true. The amount and ratio of inhibitory and excitatory neurotransmitters in the synaptic cleft determine whether or not an action potential is generated in the postsynaptic neuron. Inhibitory neurotransmitters make it less likely for the neuron to fire, while excitatory neurotransmitters make it more likely.
