“…Owing to the high integration of the brain structures, it is difficult, and perhaps incorrect, to tailor a psychiatric disorder, or even a psychiatric symptom, to a discrete brain area: it appears that, opposite to some neurological findings, the appearance of a psychological suffering is to be addressed to a set of incorrect integrative operations between different brain areas, rather than to a focused lesion. Anyway, it must be reported that this is not always true: there are cases of a depressive disorder caused by a focused neurological damage, such as a tumor, or a surgical wound, but even in those cases, the same symptomatology, as far as it can be depicted from the clinical observation, can be associated with wounds that lay in diverse parts of the brain [D'Angelo et al, 2008]. Moreover, non-responsive OCD disorders can be treated by cingulotomy or focused deep brain stimulation, but these treatments usually cannot predict the 100% of reduction of symptoms [Rauch et al, 2001[Rauch et al, , 2006Sachdev et al, 2001;Guarnieri et al, 2005], suggesting that the mechanism that leads to OCD only partially lays within a single brain area.…”
