External and internal modulation of parieto-premotor circuitry implicated in voluntary motor control

To pick a cup, the position of our fingers needs to be adjusted to its shape while its place in relation to our body steers the trajectory of our arm. Such goal directed movements are based on a combination of information of the space around us and information of our ‘body-scheme’. For the processing of this information, parietal and premotor brain areas are of crucial importance. By using functional neuroimaging we investigated brain function during (i) movements in ‘dynamic’ instead of a ‘static’ environment, (ii) movements that allowed choices and (iii) movements that were not embedded in the ‘body-scheme’ because the experimental subjects had never made such movements before.

In the brain, time is perceived based on sequential spatial states. Choices of movements could only be made of information present in our body-scheme or space around us.
