Neurophysiology Department

Service contact information

Service detail

The Neurophysiology Department carries out a range of diagnostic tests to record the electrical activity in different areas of the body. The department consists of six clinic rooms and a waiting area. There are five Consultant Neurophysiologists, doctors specialising in Neurophysiology, who work in the team with Clinical Physiologists. Apprentices and trainees may ask to perform, assist with or observe your test; however this is discussed with you prior to your appointment. We also have a department manager, healthcare assistants and several administrative staff who keep the department running smoothly.

Getting here

The Neurophysiology Department can be found in The Walton Centre Main Building, 1st floor (opposite Lipton Ward).

Neurophysiology is a Consultant referral service only

Patient leaflets

Ambulatory EEG (Electroencephalograph) Monitoring

EEG stands for Electroencephalogram. This is a recording of the electrical activity of the brain.

Audiometry

The team member will monitor your hearing levels, this is a non-invasive testing.

Brainstem Auditory Evoked Potential

This is a painless test that records the function of a nerve pathway between the ear and the brain.

Electroencephalograph (EEG) - Activation Clinic

EEG stands for Electroencephalogram. This is a well established and painless test which will record the electrical activity of the brain. 

Electroencephalograph (EEG) - Routine

EEG stands for Electroencephalogram. This is a well established and painless test which will record the electrical activity of the brain.

Electroencephalograph (EEG) - Sleep Deprived

A sleep deprived EEG is a recording of your brain waves following a period of no sleep and may provide the doctors with additional information.

Invasive Telemetry

You are having this investigation as your consultant requires more information following surface EEG recordings. 

Multiple Sleep Latency Test

The test is the standard way to measure your level of daytime sleepiness.

Nerve conduction studies (NCS) and electromyography (EMG) patient information leaflet

Your consultant would like you to have a NCS/EMG investigation.

Neurophysiology Department - Brain mapping and monitoring during surgery leaflet

Your surgeon would like you to have neurophysiology spinal cord monitoring during your surgery.

Neurophysiology Department brain mapping and monitoring during an awake craniotomy Leaflet

Your surgeon would like you to have neurophysiology mapping during your surgery. This includes motor mapping while you are asleep and language mapping when you are woken up in theatre.

Neurophysiology Department spinal cord mapping and monitoring leaflet

Your Surgeon would like you to have Neurophysiology spinal cord mapping and monitoring during your surgery. This involves mapping and monitoring of the motor and sensory parts of your spinal cord that are at risk of injury either directly from surgery or indirectly from blood loss or stroke. 

Nocturnal polysomnography (NPSG)

Your doctor would like you to have a nocturnal polysomnography investigation (NPSG).

Sleep Deprived EEG (Electroencephalogram) Patient

EEG stands for Electroencephalogram. This is a recording of the electrical activity of the brain.

Somatosensory evoked potential

Your Consultant would like you to have a somatotosensory evoked potential investigation (SEP).

Video Telemetry

This is a continuous Electroencephalogram (EEG) and video monitoring which records until sufficient information is obtained and can last up to 7 days.

WADA Test

This test helps your doctors to discover which side of your brain controls speech and memory prior to you being considered for epilepsy surgery.
