Pain-induced impulsivity is sexually dimorphic and mu-opioid receptor sensitive in rats.

Rationale And Objectives: Pain sensation can negatively impact cognitive function, including impulsivity. Pain-induced changes in impulsivity can contribute to development of psychiatric comorbidities found in those with chronic pain conditions. The goal of this study was to determine whether complete Freund's adjuvant (CFA)-induced pain manipulation enhances impulsivity in rats.
