"Form Follows Function": Anatomic and Functional Localization of Eloquent Cortex

Mai-Lan Ho¹, Rafael Rojas¹, David Hackney¹

The purposes of this exhibit are: 1. Describe imaging signs of major cortical regions on conventional CT and MR, with attention to the central sulcus and surrounding anatomic landmarks. 2. Establish the validity of anatomic techniques for localizing eloquent cortex, based on correlation to functional MRI (fMRI) activation maps in selected case studies. 3. Identify scenarios in which technical, patient, and lesion factors may limit anatomic and/or functional characterization.
