What stimulation method is used during a VEP test?

During a Visual Evoked Potential (VEP) test, the primary stimulation method involves using goggles that emit flashes of light. This approach is effective because it provides a controlled and consistent visual stimuli directly in the patient's field of view. The use of goggles allows for precise timing and intensity of the light flashes, which is crucial for eliciting the visual pathways' response and accurately measuring the electrical activity generated in the brain's visual cortex.

Furthermore, the flashing lights help in activating the visual processing pathways without the distractions or complexities that other stimuli, such as colored lights at varying intensities or static images, might introduce. The goal of a VEP test is to assess how well visual signals are transmitted from the retina through the optic nerve to the brain, and the use of goggles is a reliable method to achieve this in a clinical setting.
