I have an inquiry, for everyone here. In the litterature I've found on this site, something strikes me as contradictory. It's about what releases dopamine. Sometimes I read that dopamine is directly released by the absorption of certain substances (drugs, food) or practicing certain activities (sex). But elsewhere, I read that dopamine actually initiates the desire for this substance, and for these activities. So is dopamine released as a result of consumption of the gratifying substance or activity, or is it the neurotransmitter that actually sets you in a mood to want these kinds of things?
Thanx for helping (eventually)
