Effects of timing and movement uncertainty implicate the temporo-parietal junction in the prediction of forthcoming motor actions. |

The concept of predictive coding supposes the brain to build predictions of forthcoming events in order to decrease the computational load, thereby facilitating efficient reactions. In contrast, increasing uncertainty, i.e., lower predictability, should increase reaction time and neural activity due to reactive processing and believe updating. We used functional magnetic resonance imaging (fMRI) to scan subjects reacting to briefly presented arrows pointing to either side by pressing a button with the corresponding index finger. Predictability of these stimuli was manipulated along the independently varied factors “response type” (known hand or random, i.e., unknown order) and “timing” (fixed or variable intervals between stimuli). |
