In terms of synaptic activation, what effect does facilitation primarily have?
Understand the Problem
The question is asking about the effect of facilitation on synaptic activation, specifically looking for the correct impact it has on transmitter release and postsynaptic receptors. Facilitation is a process that affects synaptic transmission at the molecular level, and this question tests knowledge of its physiological effects.
Answer
Enhances synaptic transmission for a short duration.
Synaptic facilitation primarily results in an enhancement of synaptic transmission for a short duration, typically lasting for tens to hundreds of milliseconds.
Answer for screen readers
Synaptic facilitation primarily results in an enhancement of synaptic transmission for a short duration, typically lasting for tens to hundreds of milliseconds.
More Information
Synaptic facilitation is a form of short-term synaptic plasticity that increases neurotransmitter release, enhancing communication across the synapse temporarily.
Tips
A common mistake is confusing facilitation with depression, as both terms relate to changes in synaptic strength but have opposite effects.
