Huge congrats to Claire Lavalley on this new paper. nature.com/articles/s4139… Results show that methamphetamine users show a specific deficit in model-based planning, in which they fail to simulate plans with large short-term losses (elevated aversive pruning). Brief thread below!

Computational modeling revealed that individuals with methamphetamine use disorder show reduced information-seeking and slower belief updating when trying to maximize long-term reward. @CarterMGoldman @toru1789taka @RyanSmith_LIBR nature.com/articles/s4427…
I'm excited to attend the #ECNP Workshop on Applied Neuroscience and present our findings on markers of abnormal gastrointestinal interoception predicting relapse in anorexia nervosa. Catch Poster P107 on Thursday, March 20, & my oral presentation on Friday, March 21, at 9:10 AM
