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.
