Sensation of human pain: Perception and afferent coding

In my PhD, I have been investigating the mechanisms underlying the comorbidity between attention deficit/hyperactivity disorder (ADHD) and pain. I used behavioral approaches, morphological analysis and in vivo electrophysiology combined with optogenetics in mice.
Currently, I aim to decipher how individual sensory afferents encode painful stimuli by using microneurography (in vivo electrophysiology) and psychophysics in humans.

Our sense of touch consists of 16 unique types of nerve cells

No less than 16 different types of nerve cells have been identified by scientists in a new study on the human sense of touch. Comparisons between humans, mice and macaques show both similarities and significant differences.
