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)a decreased probability that the receiving neuron will fire.
B)an excitatory effect.
C)an inhibitory effect.
D)to prevent an action potential from occurring.
