Our group is interested to relate the mechanics of brain activity to measurable behaviour. We combine neurophysiological, imaging and behavioural techniques to investigate the neural correlates of goal-directed. We are interested in outcome value (in particular reward) signals in specific brain structures such as dopamine neurons, striatum, frontal cortex and amygdala. These rapid, global, evaluative and supervising neural signals may play a role in decision-making and choice behaviour. In investigating these outcome-coding mechanisms we try to establish a common biological basis for animal learning theory, microeconomic utility and game theories, and behavioural ecology. The larger background is to consider the brain in its capacity for processing reward information as an essential organ for assuring the fitness for survival in an evolutionary framework.
