报告题目：Cognitive Neuropsychology of Body Representations
摘 要: Individuals with impairments after amputation (phantom limbs) and brain damage have contributed to the concept of a “body schema” – an online, multisensory representation of the body in space. While the concept of the body schema has been of some heuristic value, its utility is limited by a lack of specificity. To that effect, we have proposed a new account of sensorimotor body representation – dissociating the traditional “body schema” into different subsystems. In this talk, I will discuss how evidence from individuals with brain damage can contribute to a greater understanding of how we represent the body in space. First, I will present evidence for rapid, experience-dependent shifts in tactile localization after primary somatosensory damage, and discuss how deficits in tactile localization after brain damage provide evidence for a higher-order representation of body size and shape. Next, I will use evidence from individuals with tactile and crossmodal synchiria to understand the role of interhemispheric inhibition in representing stimuli on and around the body. Finally, I will present evidence from novel illusions using a mirror box that demonstrate how stored body representations influence both multisensory integration and embodiment.
