Brain surgery is a therapeutic option for patients with intractable seizure disorders and brain tumors and the goals of surgery are twofold. On the one hand, remove epileptogenic tissue and cancerous tissue while sparing essential brain regions like primary motor and sensory cortex as well as brain areas supporting language and memory functions. The decision to perform surgery and what brain region to resect is based on several considerations including the clinical examination, history, MRI, noninvasive video-EEG monitoring, neuropsychological testing, metabolic imaging studies (PET, SPECT), functional MRI and Magnetoencephalography. If the above tests are not sufficient for reaching a decision, then an additional diagnostic procedure – invasive monitoring with implanted electrodes – is performed.

cortiQ was developed to identify functional brain regions in real-time with invasive sensors. Using that data, the system constructs and continuously updates a Mental Activity Profile (MAP). This MAP is unique for each patient, reflecting which brain areas are active during specific functions. Doctors and allied staff are able to get more relevant information than previously possible, presented in a straightforward fashion with clear and helpful images, with less work than currently required.

Pre-surgical evaluation for epilepsy and other conditions seeks to identify the affected areas (e.g. epileptic foci or tumors), as well as “eloquent” areas. The surgical procedure is then tailored such as to resect the affected areas while simultaneously sparing areas subserving important functions. Currently, the eloquent cortex is identified with electrical cortical stimulation (ECS) within 1.5 - 7.5 hours and is not completed for the majority of patients - leaving about 12 - 74% of the covered cortex unexplored. This is because either the areas had no relevance for the surgical procedure, the stimulation current produced pain or a seizure or the time was limited.

cortiQ provides physicians with real-time results during pre-surgical evaluation for epilepsy or other conditions and takes advantage of existing ECoG grids (including the Leuthardt grid).
