Abstract: &NA; Decision making related to risks and rewards has been studied in the rodent by using several behavioral tests including the use of probability discounting tasks. However, it still remains unclear how long‐term values and… read more here.

Abstract: Expected reward and risk (reward variance) are two fundamental parameters in decision making, which may be encoded by distinct functional brain networks during the anticipatory phase of reward processing. However, whether and how anticipatory reward… read more here.

Abstract: To obtain more of a particular uncertain reward, animals must learn to actively overcome the lack of reward and adjust behavior to obtain it again. The neural mechanisms underlying such coping with reward omission remain… read more here.
