About this Research Topic
While nociceptive input arrives at the brain from the periphery, pain itself is an experience produced by the central nervous system – the brain and spinal cord. Certainly, as pain becomes chronic, the relationship between pain and any injury that may have occurred becomes more tenuous. The complexity of pain has led to ongoing investigation using various forms of neuroimaging, to be explored in this issue.
While many advances have been made in our understanding of pain, there is still conjecture in the brain imaging literature. A lot of criticism is aimed at neuroimaging studies in chronic pain, for various issues e.g. sample size, type 1 error, analysis techniques. While some of this may be justified, there is always a place for well-designed studies that address clearly articulated hypotheses.
We aim for this Topic to include investigations into alternative methods and analyses in an effort to improve our understanding of pain. We also welcome studies discussing social, medicolegal, and ethical issues in pain and neuroimaging.
