It might be easy to take touch for granted—until something goes wrong. But in recent research led by Harvard neurobiologist David Ginty, and reported by Quanta Magazine on April 16, 2025, scientists are uncovering an astonishingly intricate “landscape” of cellular sensors that give rise to the rich, nuanced sense of touch. Far surpassing the simplicity of earlier textbook diagrams, these findings paint touch as the most complex human sense, rooted in a vast, diverse family of sensory neurons scattered across skin and internal organs (Quanta Magazine).
