About

Joana Coutinho is a neuroscientist whose research lies at the intersection of affective touch, pain processing, and the neural mechanisms underlying sensory perception. Her work has significantly advanced our understanding of how C-tactile (CT) afferents—slow-conducting, unmyelinated nerve fibers tuned to gentle, caressing touch—modulate pain. In her most-cited study, she demonstrated that CT-targeted stimulation can dampen the temporal summation of second pain, revealing a peripheral and central neural pathway through which pleasant touch may serve as a natural analgesic. This finding has profound implications for developing non-pharmacological pain interventions, particularly for chronic pain conditions. Coutinho’s research integrates psychophysics, neuroimaging, and electrophysiology to map the brain’s response to affective touch, bridging gaps between basic somatosensory science and clinical application. Though early in her career, her work has already garnered attention for its translational potential, and she is recognized as an emerging leader in the study of touch and pain. Her contributions continue to inspire new avenues for understanding how gentle contact can shape our experience of discomfort.
