Building on the achievements of our previous work, the second phase of our project will focus on integrating the various biological factors into circuit models of interactions between homeostatic mechanisms and reward-related signals. These models will combine recent advances in generative modelling of human neuroimaging and behavioural data with genetic, metabolic, endocrine, and immunological analyses during experimental perturbations of homeostasis and reward processing. A focus will be on obtaining compact, tractable indices of network dynamics with regard to homeostatic and affective (hedonic) valence processes that govern food choice in different states of satiety.
