Monkey electrophysiology suggests that the activity of the ventral tegmental area (VTA) helps regulate reinforcement learning and motivated behavior, in part by broadcasting prediction error signals throughout the reward system. However, electrophysiological studies do not allow causal inferences regarding the activity of VTA neurons with respect to these(More)
The cortical network that processes visual cues to self-motion was characterized with functional magnetic resonance imaging in 3 awake behaving macaques. The experimental protocol was similar to previous human studies in which the responses to a single large optic flow patch were contrasted with responses to an array of 9 similar flow patches.

Reward seeking shapes our interactions with the environment, but whether it also influences how we perceive it remains controversial. Notably, there is currently a debate on whether objects that are more likely to provide high reward might be perceived bigger than those associated with low reward. The aim of this study is to test this « wishful seeing »(More)
