Where Gliomas Start — And Why Location Should Shape Surgery

Most adult gliomas start in the frontal lobe. This short, plain-English guide shows what that means for everyday life—speech, getting started on tasks, planning, and motivation. We tour the brain’s “highways”: the dorsal and ventrallanguage routes (front↔back), the frontal aslant tract (“starter cable” for speech/action), the cingulum (motivation arc), and the frontoparietal control network (project-management system). Understanding these circuits helps teams remove more tumor while protecting the functions people notice most.
