In this study, we examined the neuronal processes
involved in an imaginary motor task using functional
MRI. 15 healthy subjects were asked to imaginary push a
cursor on a screen in different spatial directions. We
found similar, bilateral brain activations during
pushing the cursor in different spatial directions,
involving the putamen, cerebellum, middle frontal gyrus,
parietal cortex, and supplementary motor area. A
predictive analysis showed high reliability to
differentiate imaginary pushing from actual finger
tapping, but only small differences were found between
imaginary pushing in different spatial directions.
