Your body has designed a "traffic signal" for neurotransmitters. In this system, a "red light" would represent:

Question

Quizplus · Accepted Answer

Inhibitory neurotransmitters act like a "red light" in the nervous system, signaling neurons to slow down or stop firing, effectively inhibiting action potentials or neuronal activity. This is in contrast to excitatory neurotransmitters, which would be more like a "green light," encouraging neurons to fire.
