For several years we have been studying people with chronic pain, and analyzing the ways in which other aspects of their sense of touch are disturbed. For example, we have recently discovered that the ability to distinguish different frequencies of vibration is impaired in many of these individuals. Since the cortex plays a major role in frequency discrimination, our results suggest that cortical information processing is disturbed in some chronic pain patients. It is our hope that increased understanding of chronic pain conditions will lead to improved methods of diagnosis and treatment. The role of mechanoreceptive channels.
