Mechanisms of appetite, learning and addiction
Much of our daily behaviour is controlled by stimuli (cues) associated with rewards that promote survival – for instance, cues direct and attract us to nutrient sources or to potential mates. However, reward-associated cues may also promote maladaptive behaviour; for instance, food-cues may instigate overeating and cues associated with drugs of abuse can energise drug-seeking and precipitate relapse, thus contributing to addiction.
Combining behavioural neuroscience, cell-molecular and/or electrophysiological approaches, this (co-supervised by Crombag and Koya) PhD project would explore the psychological and neurobiological mechanisms mediating this type of incentive learning.
