What is a Visual Evoked Potential (VEP)?

The Nurochek device comprises a customised, wearable headset that emits a visual stimulus (as light flashes of specific design, pattern, duration and frequency) from a visor at the front of the headset which are received by the eyes of the person being tested.

This creates electrical signals in neurones (nerve cells), which are conveyed to the visual cortex in the occipital area at the back of the brain.

These are called Visual Evoked Potentials (VEPs).
