Activity in primary sensory areas is robustly driven by signals from their respective sensory inputs. However, both theory and experiment suggest that the same cortices are modulated by context-dependent internally generated activity. Predictive coding theories propose that generative models formed through learning modulate primary sensory responses on a moment-to-moment basis according to how well incoming signals conform to the animal’s predictions. Experimental data has shown that prediction errors can alter neural responses, even in the absence of behavioral relevance. Yet several aspects
