Summary

This experimental research studies the efficacy of two different treatments for inhibitory control improvement in alcohol-dependent individuals, one consisting of Retrieval-Extinction Learning ( alcohol AAT Task) and the other consisting in rTMS of the right dorsolateral prefrontal cortex.

Conditions

  • Alcoholism

Interventions

BEHAVIORAL

Retrieval-Extinction Learning

The intervention consists of the accomplishment of the task of approach-avoidance of alcohol during 4 days of training. Subjects are instructed to respond with an approach movement (pulling a lever) to neutral images and to respond with avoidance movement (pushing the lever) to images of alcohol.

OTHER

rTMS

Previous to rTMS completion, MRI scans were performed in order to determinate the motor threshold trough 1Hz stimuli and locate the desired area with the neuronavigator. Motor threshold is defined as the stimulus with less intensity, able to generate a motor potential of at least 50 µV in 10 trials. Next, patients were called for 5 times per week, along 2 weeks, for receiving brain stimulation with Magstim Rapid coil. rTMS is performed at 10 Hz, during 4.9 seconds,for each set of stimuli (20), with a interval between sets of 30 seconds.

OTHER

SAM

Previous to rTMS completion, MRI scans were performed in order to determinate the motor threshold trough 1Hz stimuli and locate the desired area with the neuronavigator. Motor threshold is defined as the stimulus with less intensity, able to generate a motor potential of at least 50 µV in 10 trials. Next, patients were called for 5 times per week, along 2 weeks, for receiving brain stimulation with SAM coil.
