Examining and understanding the effect of changing internal state (like hunger, thirst, temperature, wakefulness) on subjects’ choices and on their neural representation of value.
There is ample data describing the effect of context on behavior in general and on decision making in particular. Our aim is to investigate in a rigorous manner a specific kind of context effect. The effect of changing the internal state of individuals has on value-based decision making. The main questions in this topic are how does changes in internal state affect neural value representations, and is there evidence supporting a structure-function interaction between neural value representation and brain areas important for monitoring and affecting internal state?
