Gramsci, architettura e letteratura

"Dirigente politico comunista di alto livello e uomo di cultura raffinato, Antonio Gramsci è una delle personalità più significative tra gli intellettuali del Novecento italiano. Particolarmente notevole è l’insieme degli scritti di interesse linguistico-letterario nei quaderni vergati nei lunghi anni di prigionia sotto il regime fascista e pubblicati dopo il 1945. A rileggere oggi queste note carcerarie è facile rendersi conto che il loro punto focale è d’indole non storica ma teorica: riguarda infatti il problema generalissimo dei destinatari dell’attività di scrittura"

Implicit and Explicit Routes to Recognize the Own Body: Evidence from Brain Damaged Patients

Much research suggested that recognizing our own body-parts and attributing a body-part to our physical self-likely involve distinct processes. Accordingly, facilitation for self-body-parts was found when an implicit, but not an explicit, self-recognition was required. Here, we assess whether implicit and explicit bodily self-recognition is mediated by different cerebral networks and can be selectively impaired after brain lesion. To this aim, right- (RBD) and left- (LBD) brain damaged patients and age-matched controls were presented with rotated pictures of either self- or other-people hands. In the Implicit task participants were submitted to hand laterality judgments. In the Explicit task they had to judge whether the hand belonged, or not, to them. In the Implicit task, controls and LBD patients, but not RBD patients, showed an advantage for self-body stimuli. In the Explicit task a disadvantage emerged for self-compared to others' body stimuli in controls as well as in patients. Moreover, when we directly compared the performance of patients and controls, we found RBD, but not LBD, patients to be impaired in both the implicit and explicit recognition of self-body-part stimuli. Conversely, no differences were found for others' body-part stimuli. Crucially, 40% RBD patients showed a selective deficit for implicit processing of self-body-part stimuli, whereas 27% of them showed a selective deficit in the explicit recognition of their own body. Additionally, we provide anatomical evidence revealing the neural basis of this dissociation. Based on both behavioral and anatomical data, we suggest that different areas of the right hemisphere underpin implicit and explicit self-body knowledge
