| Research Abstract |
We developed a transcranial electrical stimulation technique to investigate cortical pathways linking primary to multimodal sensory association areas in mice. The evoked cortical responses by this method were revealed by transcranial flavoprotein fluorescence imaging. Cortical pathways arising from primary sensory areas were tracked by sequential applications of this technique. The results indicate that area 2, surrounded by visual, somatosensory and auditory cortices, receives input from all three primary sensory areas, and projects to the parietal association cortex.
