Traditionally, sensory processing and motor control have been studied separately,
reflecting the belief that sensory and motor streams remain independent until linked
via cortical "associative" areas. Although this belief no longer dominates
neuroscience, the traditional tendency to continue to study sensory processing and
motor control separately is not easily overcome. Only after closely examining
operation of sensory organs does one realize how important motor control is for
sensation. The elegant study of Herfst and Brecht (2008) reveals how accurate
sensation-targeted motor control should be in one such system - the vibrissal system.
