Brief Summary
An exacerbated response to stress mediated by activation of the Hypothalamo-Pituitary-Adrenocortical (HPA) axis is thought to play an important role in the onset, worsening and relapse of schizophrenia. Subjects at risk for schizophrenia (unaffected siblings of patients) displayed an intermediate hyperreactivity to stress as compared with patients and healthy controls. Symptoms of schizophrenia can be reduced with noninvasive brain stimulation (NIBS) applied over the dorsolateral prefrontal cortex (DLPFC). Importantly, this same DLPFC NIBS protocol can modulate decision making processes and modulate biological reactivity to stress by decreasing salivary cortisol concentration in acute stress condition.

Eligibility Criteria
You may qualify if:
- Subject to genetic risk of schizophrenia, related first-degree schizophrenic patient
- Man and woman
- Age between 18 and 30 years old
You may not qualify if:
- Contraindications to the practice of the tDCS, for safety measure, we will use the same contraindications as the practice of the Magnetic resonance imaging
- Psychiatric disorder on axis I of DSM 5
- Pregnant or nursing women

- Masking Details
- The subject will be blind of the treatment he receives (active or placebo). \- The experimenter will also be blinded from stimulation (active or placebo) Each subject will be assigned a randomization code, corresponding to the code to enter the tDCS device. This system allows the person who administers tDCS and the subject receiving the stimulation to be blind .
