IL CORPO EMOZIONALE
No full textComprendere le emozioni delle persone con le quali si interagisce attraverso l’analisi del corpo e dei suoi movimenti, è una funzione essenziale nell’interazione sociale e nell’assunzione di comportamenti adattivi. Il sistema nervoso centrale dedica all’elaborazione della forma e dell’azione del corpo osservato specifici sub- strati neurali. Recentemente, nell’ambito delle neuroscienze cognitive, lo studio sperimentale della percezione e comprensione delle emozioni a partire dall’osservazione del corpo altrui ha avuto un grande sviluppo portando alla luce alcuni correlati neurali di tale abilità. Viene sottolineato il contributo di aree moto- rie e visive nella percezione di posture corporee spaventate. L’attivazione di questi sistemi neurali insieme a strutture sottocorticali evidenzia lo stretto legame funzio- nale fra azione ed emozione. Il presente contributo inquadra le ultime scoperte in questo ambito nella generale teoria dell’embodied cognition secondo cui la rappre- sentazione mentale di una data emozione si ancora all’attività delle strutture neurali attivate durante la diretta esperienza dello stesso stato emotivo
Bodily form, actions and motor skills’ neural representations: Transcranial Magnetic Stimulation studies.
Full text linkRecent years have seen the development of new neurophysiological techniques that deepened the knowledge of neural processes underlying simple as well as complex brain mechanisms of behaviour and cognitive processes. Knowledge about body and motor representations in the brain has advanced much through the discovery of mirror neurons in monkeys and their putative homologous counterpart in humans. Simulative-like mechanisms have been proposed to be at the base of perceptive and cognitive functions. The present work focuses on neural underpinnings of visual body and action perception and motor skills representation in the motor system. These issues are at the core of plastic neural changes in action learning, understanding and higher cognitive functions as abstract motor reasoning and identity categorization. This thesis reports three studies in which these domains have been studied through single- pulse TMS and high-frequency event-related repetitive TMS procedures

No full textRecent neuroscientific studies indicate that the motor system is not only involved in movement execution but also in higher-order cognitive functions that are crucial for social interactions (e.g. perceiving the actions of other individuals). Our research demonstrates that the motor system is engaged in the predictive simulation of others' motor behaviour and that this simulation is crucial for the discrimination of observed actions. Using repetitive transcranial magnetic stimulation, indeed, we transiently interfered with neural activity of bilateral premotor and exstrastriate visual brain regions and selectively impaired the ability to discriminate others' actions and others' body identity respectively. We showed that the activity of the premotor cortex is found to be essential only for the discrimination of actions that are part of the human repertoire and do not violate biomevhanically possible body kinematics. Moreover, we reported that abstract knowledge about others' motor skills is reflected in the activity of ones' own sensorimotor system. Our research paved the way to lesion studies showing that deficits in recognizing others' identity and actions are associated with selective posterior (visual) and frontal (premotor) brain lesions
