Temporal expectations in the brain. Cortical areas involved in implicit, predictive timing. Temporal expectations, based on temporally predictable sequences, are established in left premotor-cerebellar-parietal action circuits. If the event does not occur at the expected delay, the right prefrontal cortex updates the current temporal expectations as a function of elapsed time (hazard function). Once the event occurs, the supplementary motor area and the superior temporal cortex provide an integrated estimate of how expectations evolved over time to improve the accuracy of future prediction.
