Solomon, R.B., Conover, K., & Shizgal, P. My research is funded by a Discovery grant from the Natural Sciences and Engineering Research Council of Canada (NSERC). My research team and I use a combination of psychophysical, electrochemical, electrophysiological, optogenetic, neuroanatomical and mathematical-modeling methods in our studies of the neural mechanisms underlying the evaluation, selection, and pursuit of rewards. How do animals evaluate competing goals and select alternatives that best address their biological needs? What kinds of computations are involved, and how are these computations implemented in the brain? How do animals learn the distribution of rewards and hazards in the world around them and the attendant benefits and costs? Such questions are fundamental to my research on the neural basis of reward, motivation, learning and decision making and on the roles played by dopaminergic neurons in these processes. Overview: I study the neural basis of reward, motivation, learning and decision-making. ![]()
