Pixelated Brain Module 14 Section 6 Biology Diagrams Cortical stimulation mapping (CSM) is used to evaluate eloquent cortex of the brain. In this context, as mentioned previously, eloquent cortex refers to regions of cerebral cortex that when resected would result in neurologic disability, such as language, motor, sensory, or visuospatial deficit. Cortical and subcortical stimulation mapping. Cortical and subcortical stimulation are used to map the brain intraoperatively by activating the tissue of interest (motor mapping) or by inducing temporary, reversible dysfunction that interrupts function (language mapping).
Cortical mapping is an invasive procedure in which electrical stimulation is applied briefly to the cortical surface for the purpose of identifying areas critical for sensory, motor or language function. This procedure is utilized when brain surgery involves the removal or disruption of potentially functional cortical areas. Sites identified

Modern cortical mapping is a cornerstone for safe supratentorial glioma resection in eloquent brain and allows maximal resection with improved functional outcomes. The unlocking of brain functionality through close observation and eventually via cortical stimulation has a fascinating history and was made possible by contributions from early physician-philosophers and neurosurgery's founding
The cerebral cortex receives multiple afferents from the thalamus that segregate by stimulus modality forming cortical maps for each sense. In vision, the primary visual cortex maps the multiple This threshold was used for the remainder of the mapping session. The entire exposed cortical surface was electrically interrogated, even beyond the borders of the lesion, to define a map of functionally critical brain regions . During the tumor resection, patients were asked to continuously perform specific tasks that were designed according Cortical stimulation mapping is an invasive procedure that has to be completed during a craniotomy.Once the dura mater is peeled back, an electrode is placed on the brain to test motor, sensory, language, or visual function at a specific brain site. The electrode delivers an electric current lasting from 2 to 10 seconds on the surface of the brain, causing a reversible lesion in a particular
