The Brain Senses Touch beyond the Body

An interesting article which featured in Dec-2019 in ScientificAmerican about the human sensory system and how it entangles with inanimate objects.

The summary of the research is provided in the following extract:


The extent to which a tool is an extension of its user is a question that has fascinated writers and philosophers for centuries. Despite two decades of research, it remains unknown how this could be instantiated at the neural level. To this aim, the present study combined behavior, electrophysiology and neuronal modeling to characterize how the human brain could treat a tool like an extended sensory “organ.” As with the body, participants localize touches on a hand-held tool with near-perfect accuracy. This behavior is owed to the ability of the somatosensory system to rapidly and efficiently use the tool as a tactile extension of the body. Using electroencephalography (EEG), we found that where a hand-held tool was touched was immediately coded in the neural dynamics of primary somatosensory and posterior parietal cortices of healthy participants.
