Question

Quizplus · Accepted Answer

Neuromodulators diffuse widely after release, affecting many neurons in the vicinity, rather than having a localized effect or directly eliciting postsynaptic potentials. This broad action distinguishes them from neurotransmitters, which typically have more localized, direct effects on postsynaptic potentials.
