GABA is a neurotransmitter that binds to ligand-gated chloride (Cl-) ion channels, causing Cl- to move into the post-synaptic cell. A transporte protein moves GABA back into the presynaptic cell to terminate the effect of the neurotransmitter. If a neurophysiologist applies a drug that blocks this transporter protein, what would you expect to happen to the frequency of action potentials in the post-synaptic cell relative to the case with no drug? O A. Increase in the frequency of action potentials O B. Decrease in the frequency of action potentials O C. No effect
