What is functional cortical 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.

How does cortical stimulation work?

Cortical stimulation is an emerging treatment option for a variety of neurological disorders. In contrast to deep brain stimulation where electrodes are implanted deep in the brain, cortical stimulation uses electrodes that are placed on the surface of the brain.

What is cortical reorganization?

Cortical remapping, also referred to as cortical reorganization, is the process by which an existing cortical map is affected by a stimulus resulting in the creating of a ‘new’ cortical map. Every part of the body is connected to a corresponding area in the brain which creates a cortical map.

How does cortical stimulation mapping work?

Cortical stimulation mapping is a useful, dependable, and safe technique to assess motor, sensory, and speech function. It involves the application of subdural electrodes followed by sequential electrical stimuli between two electrodes at various intensities and durations.

Can tens cause seizures?

TENS-induced seizures in a post-stroke patient have been reported, so TENS should be used with care in these patients.

How long does it take for brain mapping?

Mapping your brain takes only 20 minutes of data collection, but plan for your total visit to take around 45 minutes. What does my doctor learn from the eVox report? The eVox report will tell your doctor how well your brain functions while performing tasks, paying attention, and processing information.

What happens during brain mapping?

The brain is stimulated by applying a very low electrical current to a small area on the surface of the brain. The current is not painful and cannot be felt. The current interferes with how the area normally works. When this happens, the doctors can see which brain functions are affected.
