Some neurotransmitters are referred to as fast-acting since their cellular effects occur milliseconds after the neurotransmitter binds to its receptor. These neurotransmitters exert direct control of ion channels by inducing a conformational change in the receptor, creating a passage through which ions can flow.

Indirect acting neurotransmitters:; So these are all direct acting neurotransmitters, then we have indirectly acting neurotransmitters. Neurotensin, for example, which regulates the physiology of these cells, releases dopamine and causes an increase in phosphorylation of the DARPP-32.
