How do we know its really pain?
The US research authored by Mark Rosen of the University of California suggests that pain is a psychological construct based on experience and memory. Others such as Lrs Arendt-Neilson (a pain expert from the University of Denmark) say that too much emphasis is placed on the idea that you need a functioning cortex to feel pain. He says that patients that have suffered a brain injury in the region of their sensory cortex have still reported percieving pain. But then there are cases of events such as grimaces or flinching occuring in brain-dead or anaethetised patients undergoing surgery.So what is pain exactly? How is it defined? Natural phyical response, or psychological response?
