TL;DR: ASD was characterized by impaired striatal phasic DA release and abnormally increased functional connectivity, providing support for the social motivation hypothesis of autism.
Probabilistic Reinforcement Learning and Anhedonia Valence Systems construct of reward learning generally and sub-construct of probabilistic reinforcement learning speci fi cally. The general framework emphasizes objective measurement of a subject ’ s responsivity to reward via reinforcement
TL;DR: This chapter describes how investigating reward learning can improve the understanding of anhedonia via the four RDoC-recommended tasks that have been used to probe sensitivity to probabilistic reinforcement contingencies and how such task performance is disrupted in various neuropsychiatric conditions.

Emily L. Belleau,Rebecca Kremens,Erin Bondy,Angela Pisoni,Randy P. Auerbach,Diego A. Pizzagalli +5 more
TL;DR: In this article , the authors characterized brain dynamics in major depressive disorder and determined whether dynamic network changes are present in unaffected offspring of mothers with MDD. But whether these perturbations emerge prior to or only after MDD onset remains unclear.
