Lecture: Elena Azañon (London): Remapping Touch from Skin to Space
Elena Azañon (UCL Birbeck):
"Remapping Touch from Skin to Space"
Scheduled: 09 May 2016 14:15 to 15:00
Location: MRZ Seminar Room
When a stimulus touches the skin, the initial representation is a somatotopic map of the skin surface, which takes no account of the limb’s position in space. For tactile information from the skin to be useful as a target of directed actions, it must be ‘remapped’ to reflect the position of the limb in external space. In this talk, I will characterize this process of coordinate transformation, building on the idea that tactile remapping is ubiquitous and a default step in tactile processing. To do so, I will present evidence that touch is encoded by default every time a tactile event is presented. I will discuss the relevance of the visual modality in the creation of this external representation for touch and the idea that tactile localization in external space is based on the establishment of visuo-tactile links during development. Finally, I will provide a broad idea of the temporal course of a single remapping process and the possibility of refinement of a putative remapping system across trials.
