Phantom limbs and how your body is represented in the brain…
August 16, 2014
This is great news.
We already know that we can manipulate a person’s perception of their own body by causing them to ‘feel’ touch in a rubber hand.
But McGeoch & Ramachandran (2012) have shown that the somatosensory cortex can be manipulated to perceive fingers that the patient was born without. Because the somatosensory cortex undergoes changes in chronic pain states, this kind of manipulation helps us to start understanding how we may be able to use this kind of manipulation to help treat patients with chronic pain.
It’s all early stages but it’s a fascinating area of research and it is helping with understanding of how external factors and our internal processes are interacting to help form our conscious experience of our bodies.
