|Functional MRI (fMRI) was used to examine human brain activity within the
dorsolateral prefrontal cortex during a sensorimotor task that had been
proposed to require selection between several responses, a cognitive
concept termed "willed action" in a positron emission tomography (PET)
study by Frith et al||F. Hyder; E. A. Phelps; C. J. Wiggins; K. S. Labar; A. M. Blamire; R. G. Shulman. "Willed action": a functional MRI study of the human prefrontal cortex during a sensorimotor task.
