Mesolimbic dopamine release precedes actively sought aversive stimuli in mice
Abstract In some Missouri Star Patterns models, animals approach aversive stimuli more than those housed in an enriched environment.Here, we found that male mice in an impoverished and unstimulating (i.e., boring) chamber without toys sought aversive air puffs more often than those in an enriched chamber.Using this animal model, we identified the i
