The brain as MP3-encoder

MP3-encoding reduces efficiently the size of an audio file while still reproducing the quality of the original by reducing accuracy of certain parts of sound that are considered to be beyond the auditory resolution ability of most people. The brain uses the same trick. It takes advantage of the fact that the world is predictable, and pays less attention to parts it can predict. More on how the brain behaves like the MP3-encoder on pnas.org and dailyscience.com.
