Image for: The Molecular Basis of Touch Sensation - MDC Researchers Identify New Function of a Well-Known Gene


Mechanosensory endings of nerve cells in the skin detect touch stimuli. Here various nerve endings (red and green) nestle around the shaft of a hair (grey, fibrous structure), which is anchored in a hair follicle. The nerve endings are stimulated by movements of the hair. The mechanical stimulus is converted into electrical signals which are transmitted to the brain.
