Despite numerous studies, the neural basis of Bayesian inference during decision-making remains unclear. To address the question of where and how prior knowledge about a task is combined with sensory observations, we examine brain-wide neural recordings collected by the International Brain Lab (IBL). In the IBL task, mice indicate the location of a visual grating stimulus (left or right). Crucially, the prior probability that the stimulus appears on the left flips between 20% and 80% in blocks of variable length. The mice leveraged the block structure to improve their decision accuracy, notabl
