This project seeks to answer the question: What does it mean to experience an "illusion of pain"? At first glance, the phrase may seem contradictory. Pain is a tangible experience that feels undeniably real. We generally trust our senses, assuming that when we feel pain, it is a direct consequence of some harmful interaction with our environment or damage within our body. Yet, the term "illusion of pain" refers to instances when pain is perceived, even though the triggering stimulus is harmless and would not typically cause a painful sensation in most circumstances.
In this project, one key objective is to pinpoint the specific conditions under which harmless stimuli are perceived as painful by different individuals. We hypothesise that these illusions are not just anomalies or misconceptions of our pain perception, but rather offer insights into how pain is generated within our nervous system. Therefore, we employ these illusions as tools to understand mechanisms governing pain perception in humans.
The significance of this project is evident when considering the challenges faced by individuals with chronic pain. Many suffer from chronic pain conditions that remain elusive to current diagnostic or treatment methods. Understanding why pain occurs, particularly in the absence of a clear physical cause, can offer solace to those who are told that their pain is merely imagined or feel unjustifiably dismissed by healthcare experts. Through this project, we aim to introduce a novel perspective that frames pain through its underlying mechanisms, moving beyond "nociceptive" and "illusory" labels. We posit that pain is not merely a response to harmful environmental stimuli or damage within our body, but a reflection of the complex mechanisms governing the human nervous system.
