Effective sensory communications require massive interconnected interhemispheric cortico-cortical projections. However, little is known at present regarding the exact interactions that occur bilaterally between sensory cortices across the brain hemispheres and how they influence cortical processing. Here, we employ optogenetic stimulation of the whisker-related thalamic excitatory neurons in combination with the somatosensory forepaw stimulation. We demonstrate a novel platform to investigate the interhemispheric interactions underlying cortical sensory processing.
