Predictive coding is arguably one of the most important mechanisms to explain the interactions between the brain and the complex environment. Indeed, one of the main functions of sensory system is to predict upcoming events, which is vital for survival. Take auditory modality for instance. The neural responses to sound repetition and auditory change, such as mismatch negativity (MMN) and stimulus- specific adaptation (SSA), can be explained under a predictive coding view. As a theoretical framework, predictive coding is now facing some unresolved questions and challenges. However, combining human and animal studies under this framework will provide an excellent chance to investigate the neural mechanisms of auditory processing.

Key words: predictive coding, repetition suppression, prediction error, MMN, SSA
