Pete Clifton: feeding, obesity, schizophrenia and cognitive flexibility

What are the brain mechanisms that contribute to hunger and satiety? And how can our understanding of these systems contribute to the treatment of obesity?

What are the brain mechanisms that support cognitive flexibility? And how can such knowledge improve the treatment of schizophrenia?

How do food-related cues modulate appetitive responding in humans?

What factors best predict individual differences in appetitive responding? 

How do humans acquire liking for different foods? 
 
What factors underlie food choice?

Hans Crombag: incentive learning, addiction, appetite

How does associative learning modulate motivated action and decision-making?

What physiological- and neuronal substrates mediate incentive learning?

How do (drug) experience-dependent changes in corticostriatal circuitries affect purposive action and decision-making, including overeating and addiction?

How can basic psychology- and neuroscience research translate to inform our debate and understanding of compulsions (addiction), free-will or self-control?

Eisuke Koya: Neuronal ensembles, associative learning, obesity, addiction, synaptic physiology, immunohistochemistry

Are learned associations about food and drug rewards and their administration environment mediated by neuronal ensembles in motivationally relevant areas such as the medial prefrontal cortex and nucleus accumbens?

Do the neurons that mediate these learned associations exhibit unique synaptic physiology? Thus, are these neurons part of a unique neuronal circuit?
