Although a critical role of serotonergic neurons in the dorsal raphe nucleus DRN in reward processing has been shown, the lack of rewarding effects with selective serotonin reuptake inhibitors SSRIs implies the presence of a discrete serotonergic system playing an opposite role to the DRN in the processing of reward and aversive stimuli. Here, we demonstrated that serotonergic neurons in the median raphe nucleus MRN of mice process reward and aversive information in opposite directions to DRN serotonergic neurons. Moreover, 5-HT receptors, including 5-HT 2A receptors in the interpeduncular nucleus, are involved in the aversive properties of MRN serotonergic neural activity. Seth R. Batten, Dan Bang, … P.

The LED power was adjusted at the tip of the optical fiber to 0. Rostral and caudal ventral tegmental area GABAergic inputs to different dorsal raphe neurons participate in opioid dependence. Zhao-Shea, R. Post the Definition of raphe to Facebook Facebook. Neuroanatomy, Nucleus Raphe. Error bars indicate s. Pentkowski, N. In the pretest session, the mice were allowed to freely explore two chambers with different wall colors and textures to facilitate discrimination. Processing reward and aversive information is essential for the survival of living organisms 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , Previous reports have demonstrated that the activity of MHb neurons is increased by nicotine 85 , which leads to an increase in extracellular dopamine levels in the NAc via the activation of nicotinic receptors in the MHb 86 , indicating a critical role of MHb in the effect of addictive drugs. Paton, J. We found that the activity of serotonergic terminals in the vHP was also altered in response to aversive or reward stimuli, but the alterations were delayed compared to those in the IPN Figs. Although not highly selective to serotonin neurons, pharmacological inactivation of the MRN induced conditioned place preference and ethanol reinstatement 29 , 30 , while electrical stimulation of the MRN suppresses lever pressing associated with reward Our analyses also showed that psychotropic drugs had no significant effect on neurone numbers in any subnucleus of the dorsal raphe.

The dorsal raphe nucleus is one of the raphe nuclei. It is situated in the brainstem at the midline.

This clinical effect typically takes place over 4 to 6 weeks. To check whether the apparatus works well and obtain prototypical face data see Facial expression analysis , we infused the sucrose solution first. Hiranita, T.
