Abstract

Intention is central to the concept of voluntary action. Using functional magnetic resonance imaging, we compared conditions in which participants made self-paced actions and attended either to their intention to move or to the actual movement. When they attended to their intention rather than their movement, there was an enhancement of activity in the pre-supplementary motor area (pre-SMA). We also found activations in the right dorsal prefrontal cortex and left intraparietal cortex. Prefrontal activity, but not parietal activity, was more strongly coupled with activity in the pre-SMA. We conclude that activity in the pre-SMA reflects the representation of intention.

Lau et al. (2004) aimed to identify through fMRI the brain region that codes for the intention to perform a motor act, and concluded that the pre-Supplementary Motor Area is where this happens. Machado and Silva’s account (2007) for these results is similar to previous attempts (Bridgeman, 1985; Gomes, 2002) to interpret Libet’s original data (Libet et al., 1983). To the extent of our knowledge, however, such accounts have never been subjected to empirical test. Our objective with this paper was to provide such a test.
