Brain surgery for brain tumors or epilepsy aims to remove abnormal tissue while preserving language and movement control areas. A Northwestern Medicine study identified critical language connector sites in the brain that, when removed, lead to more language errors post-surgery. By recording brain signals, researchers pinpointed key features of these sites using graph theory and machine learning. Understanding these sites could help improve the accuracy of functional brain mapping to preserve language during surgery. The current electrical stimulation technique is limited, and this study sheds light on how language is encoded in the brain to enhance surgical outcomes in patients with brain tumors or epilepsy.
