To make sense of the acoustic environment, the auditory system must segregate, based on their history, streams of sounds arriving at the ear simultaneously. This requires sensitivity to both the probability and the predictability of the different sounds in the stream. That the auditory system is sensitive to the probability of appearance of a sound is well established. Here we presented complex sound sequences of varying predictability to anesthetized mice. Neuronal responses in the mouse inferior colliculus (IC) were recorded using Cambridge NeuroTech and Neuropixels probes. Neurons exhibited
