One of the fundamental functions of the human brain is to predict future events on the basis of the recent past. Prediction plays a prominent role in models of seemingly disparate cognitive functions such as perception, motor control, and language processing. Although there is ample behavioral evidence for the predictive nature of perception, the incorporation of prior knowledge in the neural computations underlying perception is still poorly understood.
In my lecture, I will review recent work on how prior expectations about the sensory world change the neural computations that give rise to perception. I will provide empirical evidence for generative models in perception, and show how prediction signals are integrated with bottom-up input, drawing on electrophysiological (MEG) and hemodynamic (fMRI) methods.
