#What-is-cortiQ "What-is-cortiQ"

What is cortiQ?

cortiQ was developed to help surgeons identify functional brain regions that need to be mapped and studied before the surgery to remove brain tissue. Neurosurgeons will be able to use and modify the cortiQ paradigms based on patient's individual surgical needs. cortiQ will then give the patient several tasks related to the functional proximities of the epileptic focus. For example, if the epileptic foci are close to the motor area, the system will ask to move arms, feet or even lips.

The brain activity during these movements will be transmitted in real time to the system, notifying the neurosurgeon that these parts are important for the functionality of a certain movement and therefore should remain untouched. This set up is much faster and safer than conventional technology, and reduces the risk of an accidental seizure during this mapping process or errors during surgery.

“cortiQ mapping is based on passive recordings and statistical evaluations of ECoG, rather than on active electrical stimulation and visual observation of behavior. It can be used to map motor, expressive or receptive language, and other functions, and has been shown to have good concordance to results from other imaging techniques.  Mapping can be achieved by untrained personnel in minutes, can be used in adults or children, and in the extraoperative or intraoperative scenario.”

Milena Korostenskaja, Ph.D.

“cortiQ is electrocorticography-based real-time functional mapping technique that has strong potential to become alternative to current golden standard of functional mapping–electrical cortical stimulation (ESM). There are numerous advantages of cortiQ when compared to ESM, such as flexible stimulus presentation, time- and effort- effectiveness, possibility to work with patients that are unable actively engage in the task. In addition, cortiQ is less invasive than ESM and can be effectively used in pediatric population, which other functional mapping methodologies do not always allow.”

Kyousuke Kamada, Ph.D.

Asahikawa Medical University

“On the basis of my experience, results of cortiQ had high sensitivity and specificity between 80 and 90%, which were sufficient for clinical practice. In addition, real-time CortiQ mapping made us free from risk of seizure caused by electrocortical stimulation and helped us to understand functional dynamics of each function.”


cortiQ was created to optimize surgical procedures by minimizing the burden and risks for the patient, the time to prepare and perform the surgery, all this also resulting in a reduced hospital time and overall costs.

#Benefits "Benefits of cortiQ"

Benefits of cortiQ Systems


Benefits for Physicians

With the individual real-time MAP (Mental Activity Profile) for each patient, medical experts are able to plan surgery better with more information and less work.


Benefits for Patients

CortiQ helps to reduce risk for patients because important “eloquent” brain areas get identified in order to avoid damage during the surgery. The procedure takes less hospital time and reduces surgery and recovery costs.
