Pursuit
What happens if the post–light cue release of Dopamine doesn’t occur? Crucially, the monkey doesn’t press the lever. Similarly, if you destroy its nucleus accumbens, a rat makes impulsive choices, instead of holding out for a delayed larger Reward. Conversely, back to the monkey—if instead of flashing the light cue you electrically stimulate the ventral tegmentum to release dopamine, the monkey presses the lever. Dopamine is not just about reward anticipation; it fuels the goal-directed behavior needed to gain that reward;

So we as humans are able to delay the reward for years and even to post-mortal times.
impatient people with steep temporal discounting curves; their accumbens, in effect, underestimates the magnitude of the delayed reward, and their dorsolateral PFC overestimates the length of the delay.
