摘要:
A fundamental requirement for survival is an endowment with ability to effectively seek out sources of reward. Evolutionary selection has provided humans, and other species, with highly conserved mechanisms that motivate a seeking out of rewards, as well as effective learning about the nature (value) and sources of these rewards. The action of the brain chemical, dopamine, is a key driver of these abilities. Over the past two decades scientists have made fundamental discoveries that shed new light on the action of dopamine in supporting a range of reward related behaviours. In this lecture I will summarise some of these discoveries through a focus on work from my laboratory. I will describe how a fundamental mathematical algorithm is encoded in the pattern of firing of dopamine neurons and how this has thrown light on a range of questions related to human learning and planning. I will also address how deficits in dopamine impact on learning as well as consider multi-attribute learning in realised, including learning about others.
