Keywords: action, agency, embodiment, body representation, tool, aesthetic, predjudice, Spinal cord injury, Brain-damaged injury, Neuropsychology. My career developed in domains related to voluntary actions investigating the neural basis of action recognition and execution, and the brain processes that allow the motor system to link actions to external effects ('sense of agency'). I study the clinical, behavioural, and anatomical measures of patients with stroke and praxic deficits to understand the impact of neurological disorders on neurocognitive networks. In particular, I examine the role of the left hemisphere in the recognition and execution of actions after an injury, and the contribution of different cortical areas to different types of apraxia. This knowledge is critical for developing new treatments and future therapies for brain injury that potentially drives the diagnosis and rehabilitation of goal-directed action disorders in neurological patients. My current research interests focus on a number of different innovative lines of research on neural basis of corporeal awareness in brain damaged and bodily sensations (touch, and proprioception) spinal cord injured patients. I become fascinated by the emerging field of smell and sound in social action. My new line of research focuses on how areas of the human brain are involved in timing and interoceptive processing. These processes are visualized in vivo in normal volunteers using functional magnetic resonance imaging (fMRI). I am identifying the areas of the brain that are involved in selecting relevant spatial and temporal information; further, I am studying how visual processing of timing is modulated by knowledge and expectations and how the brain generates moment-to-moment predictions in order to optimize perception and action.
