| Outline of Final Research Achievements |
A brain in which the corpus callosum connecting the left and right hemispheres has been severed for the treatment of epilepsy is called a "split-brain," and the patient behaves as if he or she has two independent consciousnesses in the left and right hemispheres. Understanding the split-brain is important to understand how we can have one consciousness integrating the left and right brains. In this study, we recorded monkey ECoG data and developed an algorithm to extract neural network structure from neural activity data with the goal of understanding the neural mechanisms of the split-brain. The algorithm is capable of efficiently searching for the subnetwork with the largest amount of integrated information, which enables us to judge the split of networks from brain activity.
