Evoked potentials measure the electrical response of the brain or spinal cord to sensory stimuli. Visual evoked potentials (VEPs) assess the visual pathway from the retina to the visual cortex, useful in diagnosing conditions like optic neuropathy. Auditory brainstem responses (ABRs) evaluate the auditory pathway, essential for diagnosing hearing impairments. Somatosensory evoked potentials (SSEPs) are used to assess the integrity of the sensory pathways in the spinal cord and brain.
