In inhibitory transmission at the synapse,the neurotransmitter hyperpolarizes the postsynaptic membrane and makes it more difficult to initiate an impulse.

Question

Quizplus · Accepted Answer

Inhibitory neurotransmitters, such as GABA, bind to receptors on the postsynaptic membrane and cause an influx of negatively charged ions or an efflux of positively charged ions, making the membrane potential more negative, which is known as hyperpolarization. This makes it more difficult for the postsynaptic neuron to reach the threshold for firing an action potential.
