RecruitingPhase 4Drug trialAnti-Inflammatory Challenge in SchizophreniaThis study aims to illuminate the biological underpinnings of negative symptoms in schizophrenia-particularly motivational impairments-by probing the link between systemic inflammation and neural activity in reward-related brain circuits. The primary goal of this study is to determine: * Ventral Striatum Activation: Assess how reward anticipation engages the ventral striatum in individuals with schizophrenia, both before and after an anti-inflammatory intervention. * Anterior Insula Activation: Examine how increasing effort demands modulate activity in the anterior insula under the same conditions.
