Question

Quizplus · Accepted Answer

Excitatory neurotransmitters increase the likelihood that a neuron will generate action potentials, while inhibitory neurotransmitters decrease the likelihood. Choice A correctly identifies these two types of neurotransmitters. Choices C and D refer to the location of the neurotransmitter (pre/post synaptic) rather than its effect on the postsynaptic neuron. Choice B switches the roles of excitatory and inhibitory neurotransmitters.
