Is the brain reward system a mechanism of the association of sleep and pain?dopaminepainrewardsleepOver a decade ago, Smith and Hayt-hornthwaite [1] reviewed and interpreted the findings from 65 studies that had examined the association of sleep and pain. The primary finding was that sleep ...

Effects of Acupuncture on c-Fos Expression in Brain After Noxious Tooth Stimulation of the Rat Clinically, acupuncture therapy is useful for the control of acute or chronic pain. This study was designed to elucidate the antinociceptive mechanism of a... MS Vang,YJ Jeong,WM Oh,... - 《Americ...
A circuit mechanism for differentiating positive and negative associations Neurons in the basolateral amygdala projecting to canonical fear or reward circuits undergo opposing changes in synaptic strength following fear or reward conditioning, and selectively activating these projection-target-defined neural po...
Brain mechanism of reward prediction under predictable and unpredictable environmental dynamics In learning goal-directed behaviors, an agent has to consider not only the reward given at each state but also the consequences of dynamic state transition...

This paper identifies an epigenetic mechanism in the NAc of depressed humans that reduces the expression of the small GTPase RAC1. It further shows that stress reduces Rac1 expression through a similar mechanism in mice and is necessary and sufficient to induce depression-like changes in behaviour...
In the CG, the VS activity was significantly attenuated. This longitudinal study revealed that video game training may preserve reward responsiveness in the VS in a retest situation over time. We suggest that video games are able to keep striatal responses to reward flexible, a mechanism which ...
through their different pharmacological effects, increase the release of DA in the shell subregion of the NAc (Di Chiara, 2002), mimicking the phasic DA neuronal firing that leads to very fast DA increases (Owesson-White et al., 2009) and thus the mechanism through which the brain signals ...
