Abstract EN:

Auditory verbal hallucinations (AVH) are a frequent, invalidating and sometimes resistant symptom. Functional brain imaging studies have demonstrated blood flow activation in left temporoparietal auditory-linguistic cortex during AVH experience. Transcranial Magnetic Stimulation is a non-invasive method of stimulating the brain that is increasingly being used in neuropsychiatric research and clinical psychiatry. Low frequency (<1Hz) repetitive Transcranial Magnetic Stimulation (r TMS) reduces activation in the brain area directly stimulated as well as in other fuctionally connected brain areas. Considered together, these two findings suggest that low frequency r TMS delivered to the left temporoparietal cortex would curtail auditory hallucinations by reducing excitability of distributed neurocircuits that produce these experiences. We developed several research works to test the r TMS as a new HAs treatment and to maintain this effect for a long time. We also studied the effect of this treatment on a source memory test. In this review, we present 4 published articles which show effects of the r TMS in this indication and let us appoach other research perspectives in electrophysiology but also in other areas
