For example, in the case of resistant depression, a study showed that repeated transcranial magnetic stimulation (TMS) was more effective by targeting the left pre-frontal regions. Patient characteristics allowed a profile of responders and non-responders to be defined by pre-treatment image analysis alone (Paillere et al, Int. J. Neuropsychopharmacol. 2011).<\/p>\n<p><a href=\"https:\/\/www.inserm-u1000.universite-paris-saclay.fr\/wp-content\/uploads\/2022\/08\/ml-2011.png\"><img decoding=\"async\" loading=\"lazy\" class=\" wp-image-1798 aligncenter\" src=\"https:\/\/www.inserm-u1000.universite-paris-saclay.fr\/wp-content\/uploads\/2022\/08\/ml-2011-300x257.png\" alt=\"\" width=\"325\" height=\"278\" srcset=\"https:\/\/www.inserm-u1000.universite-paris-saclay.fr\/wp-content\/uploads\/2022\/08\/ml-2011-300x257.png 300w, https:\/\/www.inserm-u1000.universite-paris-saclay.fr\/wp-content\/uploads\/2022\/08\/ml-2011.png 423w\" sizes=\"(max-width: 325px) 100vw, 325px\" \/><\/a><\/p>\n\n\n\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3230494\/pdf\/npp2011161a.pdf\">https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3230494\/pdf\/npp2011161a.pdf<\/a><\/p>\n<p style=\"text-align: justify;\">Schizophrenic hallucinations: TMS targeting language regions was no more effective than placebo.
