The lesion-studies team has research interests in a bi-directional link between action perception and execution in healthy individuals and in patients with stroke. Our team attempts to develop the understanding of the perceptual, motor, emotional, and cognitive functions involved in multimodal demonstrations of goal-directed behaviour. Much of our research focuses on individuals with impairments that affect their ability to execute actions, a condition called as apraxia. Evidence obtained from patients with apraxia facilitates the understanding of the nature and the development of the mechanisms underlying action execution and perception and the brain sites involved in these mechanisms; it also helps to elucidate whether training can improve the skills of functioning in such patients. Using state-of-the-art lesion mapping techniques combined with new behavioural paradigms we also investigated the causative role of specific cortical areas on the human Motor/Sensory brain.
