In this paper we describe how three discrete neuronal inputs to the rostromedial tegmental nucleus (RMTg), including the prelimbic cortex, lateral habenula, and parabrachial nucleus, mediate separable aspects of both learning from and responding to aversive experiences.
Learning from one's mistakes: a dual role for the rostromedial tegmental nucleus in the encoding and expression of punished reward seeking.

Here, we provide the first evidence that the rostromedial tegmental nucleus mediates not only learning from an aversive event, but also behavioral inhibition in anticipation of a future aversive outcome. We go on to characterize the involvement of this enigmatic brain region in a variety of rodent behavioral paradigms.
Gene expression and neurochemical characterization of the rostromedial tegmental nucleus (RMTg) in rats and mice.

In this paper, spearheaded by Dr. Rachel Smith, we provide a detailed identification and comparison of the rostromedial tegmental nucleus in both rats and mice. Given inherent difficulties in delineating the boundaries of the RMTg in rodents, this paper unlocks a pathway for expanding research into this brain region through immunohistochemical staining for the protein FoxP1.
Bidirectional regulation of reward, punishment, and arousal, by dopamine, the lateral habenula, and the rostromedial tegmentum (RMTg).

In this review, we discuss recent advances in our understanding of the diverse roles of the RMTg, lateral habenula, and dopamine neurons, in aversive learning and behavior. We explore the potential involvement of these circuits in neuropsychiatric diseases, including depression and mania.
