Methamphetamine dependent individuals show attenuated brain response to pleasant interoceptive stimuli

Conclusions: MD expend fewer brain processing resources during soft touch, a form of positively-valenced interoceptive stimuli, in brain areas that are important for both interoception and reward. Future studies will ascertain if sustained abstinence from methamphetamine use can normalize aberrant neural interoceptive processing.
