Electro Encephalograph

Electroencephalography, technique for recording and interpreting the electrical activity of the brain. The nerve cells of the brain generate electrical impulses that fluctuate rhythmically in distinct patterns

Nerve Conductors

It is used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body.These tests may be performed by medical specialists such as clinical neurophysiologists, physical therapists...

Electromyograph Studies

Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram

Visual Evoked Potential

A visual evoked potential is an evoked potential caused by a visual stimulus, such as an alternating checkerboard pattern on a computer screen. Responses are recorded from electrodes that are placed on the back of your head and are observed as a reading on an electroencephalogram (EEG)

Brainstem Auditory Evoked Response

are very small auditory evoked potentials in response to an auditory stimulus, which are recorded by electrodes placed on the scalp. They reflect neuronal activity in the auditory nerve, cochlear nucleus, superior olive, and inferior colliculus of the brainstem.They typically have a response latency of no more than six milliseconds with an amplitude of approximately one microvolt.
