Divergent Movement of Adjacent Whiskers. J. Neurophysiol. 87: 1440-1448, 2002. The current view of
whisker movement is that ~25 whiskers on each side of the face move
in synchrony. To determine whether whiskers are constrained to move
together, we trained rats to use two whiskers on the same side of the
face in simple behavioral tasks and videotaped the whiskers during the
task. Here we report that the movement of adjacent whiskers is usually
synchronous but can diverge: 1) the distance between
whiskers can vary dramatically during movement; 2) one
whisker can move while the second one remains stationary; 3)
two whiskers can simultaneously move in opposite directions; and
4) one whisker can be maintained in contact with an object
while the other is retracted and protracted. The frequency of whisker
movement during the task falls within the previously reported range for
rats whisking freely into air or performing roughness discrimination
with their whiskers. Our data also suggest that whisker movement can be
divided into three distinct phases: protraction, retraction, and a
measurable delay between these movements. We conclude that, although
whiskers often move in concert, adjacent caudal whiskers can be moved
independently of each other.
