MRI scans

Functional MRI

In the last 10 years we have been using functional MRI (fMRI) at Epilepsy Society's Chalfont Centre to map where different functions such as language and vision occur in the brain. For example our research has enabled us to see exactly which part of the brain we use if we want to think of words, name objects or describe a picture. This ability to visualise the communication and thought networks in the brain is enabling us to protect these during surgery and assess how some medications may affect our speech and cognitive abilities.

Brain scans

Despite advances in technology, around 30 per cent of people with seizures arising from one part of the brain have completely normal MRI scans. We are assessing several new MRI techniques to determine which are helpful in identifying the source of seizures in people with severe epilepsy and normal standard scans. We hope these developments will enable a larger proportion of people with epilepsy to undergo surgery and be cured or their epilepsy significantly improved.

Epilepsy Navigator

Epilepsy Navigator is an interactive 3D-neuronavigation system that  enables the best operative approach for inserting electrodes into the brain in order to pinpoint the areas where seizures arise from. These plans are now being used to direct a robotic system for placing the electrodes through the skull and into the brain.
