It makes it possible to work on stuff you don't particularly enjoy by focussing on an expected long-term reward. This statement asserts causation where only correlation, particular of neural correlates, only justifies. That part of the brain plays a role in the process of expectation — it does not, by itself, make it possible. Language, other brain functions, social inertia, etc. makes expectation possible, and there is a critical question of the content of expectation. Cannabis obviously increases appetite and drives a greater motivation for munchies. Therefore, the reduction of dopeminergic brain-activity alone does not isolate cannabis as the defeater of all motivation but rather of certain kinds of motivation dependent on pleasure-data. Obviously what if I derive pleasure from making logical deductions or from reading? What of children who are synesthes, and who mix up stimulae as a neurotypicality modality that is atypical?
