Alternating innocuous warm and cold stimuli on the skin can strangely provoke a hot and burning sensation. This misperception of heat and pain resembles cold allodynia a common symptom in patients with polyneuropathy. In this talk, I will present novel protocols to investigate pain and heat illusions, based on the thermal grill illusion or TGI (i.e., spatial alternations of warm and cold stimuli) and the thermal sensory limen or TSL paradigm (i.e., temporal alternations of warming and cooling). The TGI has been largely investigated in healthy individuals, while the TSL is commonly used to assess paradoxical heat sensations (PHS) in patients with neuropathy. I will discuss how new TGI protocols can be used to investigate spinal integration of thermo-nociceptive afferent inputs and how new TSL protocols may redefine our functional interpretation of thermo-nociceptive illusions.
