Making Sense of Touch


Our relationship with the physical world is rich, complex, and essential for virtually all aspects of life. How does the nervous system encode component dimensions of a tactile stimulus –pressure, sharpness, vibratory frequency, roughness, wetness, adhesiveness, and compliance– and superimpose these dimensions with respect to stimulus location on the body and direction and speed of stimulus movement? In this lecture I will describe properties and functions of the cutaneous mechanoreceptors, which are the primary sensory neurons of touch, and the form underlying their function. I will also highlight recent insights into the central representation of touch, including some surprising findings regarding the central representation of mechanical vibration, and the functional organization of the subcortical somatosensory system.
