Testing Question

[merlot3106]

Does anyone know what SSEP and BAER test are for and how they do them?

Thank for your help ahead of time!

The hearing test known as the brainstem auditory evoked response (BAER) or brainstem auditory evoked potential (BAEP) detects electrical activity in the cochlea and auditory pathways in the brain in much the same way that an antenna detects radio or TV signals or an EKG detects electrical activity of the heart. The response waveform consists of a series of peaks numbered with Roman numerals: peak I is produced by the cochlea and later peaks are produced within the brain. The response from an ear that is deaf is an essentially flat line. In the sample recordings shown below, Puppy 1 heard in both ears, Puppy 2 was deaf in the left ear, Puppy 3 was deaf in the right ear, and Puppy 4 was deaf in both ears. Because the response amplitude is so small it is necessary to average the responses to multiple stimuli (clicks) to unmask them from the other unrelated electrical activity that is also present on the scalp (EEG, muscle activity, etc).


Somatosensory Evoked Potential (SSEP) is a test showing the electrical signals of sensation going from the body to the brain.

Sounds a bit more involved than an EMG ...but on the same order.

Hi Meg,

SSEP:These are Nerve Conduction Tests to check the health of your nervous system by checking how well it conducts messages from the skin to the brain


BAER
Brainstem Auditory Evoked Responses test is a type of hearing test, it detects electrical activity in the cochlea and auditory pathways in the brain

Thanks to you both. I had never heard of eiter of these test so I sort of wanted to know what I was in for.

Thanks,
