When a neurotransmitter molecule binds briefly with a receptor site, changes occur in the receiving neuron's membrane. If there is a voltage shift in a positive direction then the effect is:
A) an inhibitory effect.
B) a decreased probability that the receiving neuron will fire.
C) an excitatory effect.
D) to prevent an action potential from occurring.
