Cortical Evoked Potential (CEP)

Cortical Evoked Potential (CEP)

The potential clinical advantages for determine brain encoding and plasticity in hearing aid users have driven a rising importance in CEP. It aids in understanding the effect of hearing aids on brain performance and resulting behaviour, may advance the contemporary science underlying thriving rehabilitation of hearing loss.

Cortical Evoked Potential or CEP is a test depends whether we are testing your child while wearing a hearing aid or without. The test is also known as Auditory Evoked Potential where small electrical signals are generated in brain by a hearing pathway. A loudspeaker is used with frequency variation to make several speech sounds (like m, g, and t). The stimulation are carried inside the brain and they can are recorded from the surface of the head via a electrode and analysed on a computer device.

Why to take CEP Test?

In infants and young children where testing for hearing loss problem cannot be detected through observation or whether hearing aids have been fitted or adjusted optimally. There is no need of behavioural response during the Cortical Evoked Response Eudiometry.

What to expect?

Three electrodes are attached to the surface of the child head with the help of a surgical tape. The electrodes do not cause any discomfort while there are possibilities that the procedure might cause some reddening of the skin that can last up to 24 hours. It is a safe procedure and there will be no harm to the baby.

During the event, hearing aid signals are used to create stimuli to elicit CEP. Then these signals outputs from the hearing aids are recorded.

Additional Test

Your doctor may include some additional test to help interpret results of CEP. Both tympanometry and otoacoustic emission routine procedures are used by an audiologist to test infants.
