Perspectives

NEUROSCIENCE:
The Where and When of Intention

David M. Eagleman

Although a subjective urge-or intention-to act appears to precede a voluntary action by almost a quarter of a second, neuroscientists have not had a clear picture of the brain activity that underlies this intentional state. In his Perspective, Eagleman discusses new work (Lau et al.) that uses functional magnetic resonance imaging to distinguish brain areas that are activated in response to the intention to move versus the actual movement.
