简要总结

During the first funding period (1st FP), the investigators developed a novel full Pavlovian-to-instrumental transfer (PIT) task that allows assessing both, general and specific PIT to investigate whether specific PIT differs between alcohol use disorder (AUD) and control subjects. Preliminary analyses of the full transfer task indicate that AUD participants exhibit a stronger specific PIT effect compared to controls. Based on these findings, the investigators want to compare specific and general PIT effects in patients with moderate to severe substance use disorders (alcohol, cannabis, methamphetamine, amphetamine and cocaine) to healthy controls on the behavioral and neural level (fMRI).

详细描述

This projects research aim:

  1. The investigators aim to compare general and specific PIT effects in patients with moderate to severe substance use disorder (Alcohol, Methamphetamine, Amphetamine and Cocaine) and healthy controls using the newly developed (1st FP) full transfer task and fMRI The investigators expect enhanced general PIT effects in patients compared to controls at the behavioral level, and at the neuronal level enhanced PIT-associated activations in the striatum, and lower activation in the prefrontal cortex (e.g., dlPFC).

The investigators expect enhanced general PIT effects in patients with multiple SUD compared to patients with single SUD.

The investigators expect increased behavioral and neuronal alcohol-specific PIT effects in patients groups that also meet AUD criteria compared to controls and to patients without AUD.

The investigators expect stronger behavioral and neural PIT effects (both general and specific) to predict more substance use at 3-month follow-up.
