Current theories of perception suggest that we continuously update an internal model of the
world to infer the probable causes of sensory events, which facilitates sensory processing. In
this framework, the brain needs not only to predict the causes of sensory inputs (‘what’ is
going to happen), but also ‘when’ they are most likely to happen. According to this
distinction, I will argue that the classical dorso-ventral (‘what’ vs. ’where/how/when’)
segregation of feed-forward inputs extends to the notion of top-down predictive
mechanisms to support distinct types of inferences about upcoming events. I will focus on
the putative neurophysiological bases of sensory predictions of ‘‘what’ (predictive coding)
and ‘when’ (predictive timing), with an emphasis on low-level oscillatory mechanisms. I will
argue that neural rhythms offer distinct and adapted computational solutions to predicting
‘what’ is going to happen in the sensory environment and ‘when’.
