Activity

We study the mind-brain system through several methods, including human participant experiments, injury studies, neuroimaging techniques (in particular fMRI), brain stimulation (in particular tDCS). From a theoretical point of view, the aim is a greater knowledge of cognitive functions and of their neural correlates. From an applicative point of view, the aim is the development of clinical protocols for the assessment and/or rehabilitation of patients with central nervous system dysfunctions.                                                                                             Here are some examples.

Regarding the motor functions, we have realized a gait rehabilitation protocol, in collaboration with the Department of Mechanical and Aerospace Engineering of the Polytechnic of Turin. The protocol consists of sensory motor stimulation implemented through a robotic orthosis that elicits lower limbs movements (Pneumatic Interactive Gait Rehabilitation Orthosis, P.I.G.R.O.) and a cognitive training performed by using the motor imagery.                                                                               For example, see

With regard to cognitive functions, in collaboration with the GIPSI research group, we have developed a battery for communication skills assessment (Assessment Battery for Communication, ABaCo) and a rehabilitation protocol based on the same theoretical assumptions and focused on training of dysfunctional communicative abilities.                                                For example, see

Furthermore, in collaboration with IT companies, we develop methods for memory and spatial abilities training and rehabilitation using virtual reality technology.

We use neuroimaging techniques with different purposes, specifically to explore brain changes (plasticity) after training.                                                               For example, see

Crucially, with neuroimaging techniques, we also study the neural correlates of motor and cognitive functions in healthy subjects. For example, see

Cauda F, Geminiani G, D'Agata F, Duca S, Sacco K. (2011). Discovering the somatotopic organization of the motor areas of the medial wall using low-frequency BOLD fluctuations. Hum Brain Mapp. 32(10):1566-79.

Additionally, we use brain stimulation techniques to rehab neurological deficits in patients with brain injury.                                                                                                          For example, see
