The minimum intensity level at which a neonate responds to sound is 25 dBs.
This minimum level gradually decreases through infancy and at 36 months most children respond to sound intensities of less than 10 dBs.
It is simpler than ABR, and it can be used to screen infants for severe hearing losses, since if hearing loss of greater than 40 dBs exist, no emission will be recorded.
Deep brain stimulation (DBS) is a way to inactivate the parts of the brain thought to cause overactivity or tremor in certain muscles, without destroying a part of the brain.
During the DBS procedure, an electrode placed in a precise area of the brain delivers small, electrical shocks to interrupt the abnormal brain activity that leads to symptoms.
