Learning a new task is accompanied by changes at multiple levels in the brain. At the neuronal population level, learning requires coordinated adaptations to achieve optimal sensory processing and appropriate behavioral output. To understand how learning shapes high-dimensional neuronal dynamics across cortical areas, we simultaneously imaged the activity of neuronal populations in mouse somatosensory (S1) cortex and posterior parietal cortex (PPC) while mice were learning a multisensory texture discrimination task. Mice were trained to discriminate two textures, each preceded by a distinct au
