We found neural dynamics that could support the seamless transfer of information between the cerebral hemispheres. We expect some of these same mechanisms are also used when interhemispheric communication is required for other cognitive processes, such as tracking moving objects across the midline or comparing visual information between the left and right hemifields. Fast, reliable interhemispheric communication is critical for many real-world behaviors, including sports, driving, and air traffic control. Interhemispheric communication is also thought to be disrupted in some disorders, such as dyslexia (Dhar et al., 2010). We hope that an understanding of the neural mechanisms of interhemispheric communication may lead to new ways to repair and optimize it.
