In the present study, we used the functional near‐infrared spectroscopy (fNIRS) cutting‐edge technique to examine the hypothesis that prefrontal inhibitory control is needed to perform slow motor activities. Participants were asked to perform a sensorimotor‐synchronization task at various paces (i.e., slow, close‐to‐spontaneous, fast). We contrasted upper‐limb circle drawing to a more naturalistic behavior that required whole‐body movements (i.e., steady‐state walking). Results indicated that whole‐body movements led to greater brain oxygenation over the motor regions when compared with upper‐limb activities. The effect of motor pace was found in the walking task only, with more bilateral orbitofrontal and left dorsolateral activation at slow versus fast pace. Exploratory analyses revealed a positive correlation between the activation of the orbitofrontal and motor areas for the close‐to‐spontaneous pace in both tasks. Overall, results support the key role of prefrontal cognitive control in the production of slow whole‐body movements. In addition, our findings confirm that upper‐limb (laboratory‐based) tasks might not be representative of those engaged during everyday‐life motor behaviors. The fNIRS technique may be a valuable tool to decipher the neurocognitive mechanisms underlying naturalistic, adaptive motor behaviors.Show less >
