Question

Inhibition of neural activity can result from

A. presynaptic events only.

B. postsynaptic events only.

C. presynaptic events and postsynaptic events.

Answer 1

Inhibition of neural activity can result from presynaptic events and postsynaptic events.

Step-by-step explanation:

The inhibition of neural activity can result from presynaptic events and postsynaptic events. Neurotransmitters can have excitatory or inhibitory effects on the postsynaptic membrane. For example, when the neurotransmitter GABA is released from a presynaptic neuron, it binds to and opens Cl- channels, causing a hyperpolarization of the membrane and making the neuron less likely to fire an action potential.
