The perception of an ambiguous stimulus rely on the activation of multiple cortical areas, operating a sensorimotor transformation along the cortical hierarchy. Furthermore, choice related information is found as upstream as the primary sensory areas, suggesting bi-directional communication at all stages of the cortical hierarchy. How do sensory and choice related activities flow and organize across multiple brain areas? Here, we designed a two-alternative forced-choice task (2AFC) in which mice compared stimulation frequencies applied to two adjacent vibrissae. Using two-photon functional ima
