What are two basic functional distinctions between synaptic neurotransmission and nonsynaptic diffusion neurotransmission (volume transmission) in the brain?
What will be an ideal response?
With synaptic neurotransmission, neurotransmitters are released in the close proximity to their receptors and most likely induce relatively quick, short duration actions on target neurons. Also, receptor affinity is relatively low. With nonsynaptic neurotransmission, neurotransmitters are generally released from cells relatively far away from their target receptors and are more likely to induce relatively slow onset, long-lasting actions on the target neurons. Receptor affinity is relative high.
