Intraoperative stimulation [[mapping]] of [[subcortical]] [[white matter]] [[tract]]s during the resection of [[glioma]]s has become a valuable surgical adjunct that is used to reduce [[morbidity]] associated with [[tumor]] removal. Enables extensive [[resection]] of [[tumor]]s in [[eloquent]] locations ((De Witt Hamer PC, Robles SG, Zwinderman AH, et al. Impact of intraoperative stimulation brain mapping on glioma surgery outcome: a meta-analysis. J Clin Oncol 2012;30(20):2559-2565.)) ((Sanai N, Berger MS. Intraoperative stimulation techniques for functional pathway preservation and glioma resection. Neurosurg Focus 2010;28(2):E1.)). The use of subcortical stimulation allow identification of specific [[white matter]] [[tract]]s associated with reading, writing...
