Task-based BOLD fMRI enables the evaluation of the spatial relationship between an intracranial lesion and different cortical functional areas (e.g., primary motor cortex or lateralization of essential language areas Stippich, 2015).Ĭontrary to research fMRI studies, presurgical clinical fMRI is usually based on a simple block design and the control condition is usually rest or visual fixation. Since its first description in 1992 ( Ogawa, 2012 ), fMRI based on BOLD contrast has gained an important role in presurgical brain mapping.
