Ok, first I heard of this but I’m going to learn:
Increasing activity in Left Inferior Parietal Cortex and right Prefrontal Cortex with increasing temporal predictability: An fMRI study of the hazard function
The longer we wait for an event to occur, the higher the probability that it will soon arrive (the “hazard function”). Confirming previous findings, we found that RTs decreased across the foreperiod when target onset was unpredictable/variable but remained constant when it was predictable/fixed.
Left inferior parietal cortex was activated not only by fixed prior temporal predictions but also as a function of the evolving temporal predictability across the foreperiod.
By contrast, right prefrontal cortex was activated by evolving, but not by fixed, temporal predictions. Importantly, brain activity associated with evolving predictability was independent from that underpinning perception of the foreperiod duration itself.
Yes! I think so! Looks like the Left IPC activates with temporal certainties: upcoming events. Called the “Hazard Function”
So if it’s deactivating, that means there no more sense of temporal certainty.
