____ is the process by which inhibitory transmitters cause the inside of the neuron to become more negative
(b) Inhibitory transmitters cause hyperpolarization, an increased negative charge inside the axon. The charge inside the axon must reach the dashed line to trigger an action potential. Effect of excitatory (E) and inhibitory (I) input on the firing rate of a neuron. The amount of excitatory and inhibitory input to the neuron is indicated by the size of the arrows at the synapse.
