When an inhibitory neurotransmitter such as GABA opens Cl' channels in the plasma membrane of a postsynaptic neuron, why does this make it harder for an excitatory neurotransmitter to excite the neuron?
How does neurotransmitter binding to receptors on a postsynaptic cell cause inhibition or excitation?
The neurotransmitter GABA exerts its inhibitory action on neurons in the brain by; Group of answer choices invariably activating an inward current in the postsynaptic neuron. invariably activating an outward current in the postsynaptic neuron. invariably causing chloride ions to enter the postsynaptic neuron. itself crossing the postsynaptic membrane and, because it is a negatively charged amino acid, thus hyperpolarizing the neuron. increasing the conductance of the postsynaptic membrane to Cl- ions..
