Transfer of Coded Information from Sensory to Motor Networks

During sensory-guided motor tasks, information must be
transferred from arrays of neurons coding target location
to motor networks that generate and control movement. We
address two basic questions about this information trans-
fer. First, what mechanisms assure that the different neural
representations align properly so that activity in the sen-
sory network representing target location evokes a motor
response generating accurate movement toward the tar-
get? Coordinate transformations may be needed to put the
sensory data into a form appropriate for use by the motor
system. For example, in visually guided reaching the lo-
cation of a target relative to the body is determined by a
combination of the position of its image on the retina and
the direction of gaze. What assures that the motor network
responds to the appropriate combination of sensory inputs
corresponding to target position in body- or arm-centered
