Intense reward activation and subsequent neurochemical downregulation in reward and stress pathways can trigger short-term dysphoria and negative affective states.

The analysis

The retrieved papers consistently demonstrate that intense activation of reward pathways (such as through drugs of abuse or highly palatable stimuli) leads to opponent neuroadaptations, including the downregulation of reward function and the recruitment of stress systems, which collectively produce dysphoria and negative emotional states.
