Goal-directed behaviour can be considered as a dynamic
link between a sensory stimulus and a motor act.
Between the transduction of sensory stimuli into bio-
chemical energy and the muscle contractions that are
needed to move a motor effector, several intermediate
processes must be carried out.These processes include
changes in the locus of attention1,2
,response selection36
,
coordinate transformations712
and a decision to`act'on
the sensory stimulus1316
.
Neural correlates of many of these intermediate
events are reflected in activity in the posterior parietal
cortex (PPC)3,79,1315,17
. In this review, we examine the
involvement of the PPC in the coordinate transforma-
