Corneil, Brian D. and Richard A. Andersen. Dorsal neck muscle
vibration induces upward shifts in the endpoints of memory-guided
saccades in monkeys. J Neurophysiol 92: 553566, 2004. First pub-
lished March 3, 2004; 10.1152/jn.00030.2004. Producing a movement
in response to a sensory stimulus requires knowledge of the body's
current configuration, and spindle organs embedded within muscles
are a primary source of such kinesthetic information. Here, we sought
to develop an animal model of kinesthetic illusions induced by me-
chanically vibrating muscles as a first step toward a mechanistic
understanding of how kinesthesia is integrated into neural plans for
action. We elected to examine the effects of mechanical vibration of
