COMMabstract
Microneurography allows us to probe the human peripheral nervous system and record from cutaneous afferents. The majority of work has focused on touch, with only a handful of recordings from human thermoreceptive afferents. However, it is clear that touch and temperature go hand-in-hand when we interact with our environment. I provide evidence that touch afferents can be modulated by temperature, which opens the possibility that tactile-thermal interactions could be signaled at the first stage of encoding. This has implications for somatosensory perception, such as how we easily sense wetness, and single afferents may provide more complicated signals that previously believed.
