Supplementary motor area encodes reward expectancy in eye-movement tasks.
Neural activity signifying the expectation of reward has been found recently in many parts of the brain, including midbrain and cortical structures. These signals can facilitate goal-directed behavior or the learning of new skills based on reinforcements. Here we show that neurons in the supplementary motor area (SMA), an area concerned with movements of the body and limbs, also carry a reward ...

متن کاملEye Field Encodes Reward Prediction Error
The outcomes of many decisions are uncertain and therefore need to be evaluated. We studied this evaluation process by recording neuronal activity in the supplementary eye field (SEF) during an oculomotor gambling task. While the monkeys awaited the outcome, SEF neurons represented attributes of the chosen option, namely, its expected value and the uncertainty of this value signal. After the ga...
متن کاملSupplementary eye field encodes option and action value for saccades with variable reward.
We recorded neuronal activity in the supplementary eye field (SEF) while monkeys made saccades to targets that yielded rewards of variable amount and uncertainty of delivery. Some SEF cells (29%) represented the anticipated value of the saccade target. These neurons encoded the value of the reward option but did not reflect the action necessary to obtain the reward. A plurality of cells (45%) r...
متن کاملSupplementary Eye Field: Keeping an Eye on Eye Movement
The supplementary eye field has the biggest say in choosing what we look at, but has long been an enigma. Recent studies are beginning to make more sense of what it actually does.
