Even if it doesn't trigger action potential, a slight somatic depolarization can still spread and modulate the neurotransmitter release at distant sites along axons. Here, the authors find that depolarization in the cerebellar molecular layer interneurons can affect presynaptic neurotransmitter release in a calcium-dependent and voltage-sensitive Ca2+ channel–dependent manner.
