Final answer:
Inhibitory neurons can either suppress or facilitate behavior.
Step-by-step explanation:
Inhibitory neurons do not always inhibit behavior. In fact, they can either suppress or facilitate behavior, depending on the context and the specific neural circuit involved.
When an inhibitory neuron is activated, it releases neurotransmitters that inhibit the firing of the postsynaptic neuron, making it less likely to generate an action potential. This inhibition can suppress or dampen the overall activity of the neuronal network, contributing to the regulation of behavior.
However, it's important to note that inhibitory neurons can also have a facilitating effect on behavior. In some neural circuits, inhibitory neurons can actually enhance and shape the activity of the postsynaptic neurons by creating a temporal window for precise firing, synchronizing activity, or controlling the amplitude and duration of excitatory inputs.
Therefore, the correct answer is B) No, inhibitory neurons can either suppress or facilitate behavior.
