The Baer test, also known as the Brainstem Auditory Evoked Response (BAER) test, is a diagnostic tool that uses electrodes to measure the electrical activity in the auditory pathway, helping to assess hearing function and identify potential auditory nerve and brainstem abnormalities.

An Electroencephalogram (EEG) test records the electrical activity of the brain through electrodes placed on the scalp, used to diagnose various neurological conditions and study brain function.

Nerve Conduction Velocity (NCV) test is a diagnostic procedure that measures the speed at which electrical impulses travel along peripheral nerves, aiding in the assessment of nerve damage and related disorders.

An Electromyogram (EMG) test involves placing electrodes on muscles to record and assess the electrical activity, aiding in the diagnosis of neuromuscular disorders and evaluating muscle function.

Visual Evoked Potential (VEP) test measures the brain's electrical responses to visual stimuli, assisting in the diagnosis of visual pathway disorders and neurological conditions affecting vision.
