Neurophysiological Testing Center

The neurophysiological testing center performs the full range of functional examinations of the nervous system, enabling precise diagnosis of neurological and neuromuscular conditions.

Services & Examinations

Standard electroencephalogram (EEG)

Recording of the brain's electrical activity at rest and during stimulation, making it possible to detect functional abnormalities of the brain.

30 to 45 minutes

Sleep electroencephalogram

Recording of the brain's electrical activity during sleep, particularly useful for detecting epileptic abnormalities that appear only during sleep.

1 hour 30 to 2 hours

Prolonged video-EEG (continuous monitoring)

Simultaneous and prolonged recording of the brain's electrical activity and the patient's behaviour by video, making it possible to correlate clinical manifestations with EEG abnormalities.

24 hours to 5 days depending on the indication

Needle electromyography (EMG)

Examination exploring the electrical activity of muscles at rest and during contraction, making it possible to diagnose muscle disorders and peripheral nerve conditions.

30 to 60 minutes

Nerve conduction studies (NCS)

Measurement of the speed and quality of transmission of the nerve impulse along the peripheral nerves, essential for the diagnosis of neuropathies.

30 to 60 minutes

Visual evoked potentials (VEP)

Recording of the electrical response of the visual cortex to a light stimulation, making it possible to assess the integrity of the visual pathways from the optic nerve to the occipital cortex.

30 to 45 minutes

Auditory evoked potentials (AEP)

Recording of the electrical responses of the auditory pathways from the cochlear nerve to the brainstem, making it possible to assess hearing and the integrity of the central auditory pathways.

30 to 45 minutes

Somatosensory evoked potentials (SEP)

Recording of the electrical responses of the sensory pathways from the peripheral nerves to the cerebral cortex, assessing the integrity of the lemniscal pathway.

45 minutes to 1 hour

Motor evoked potentials (MEP)

Assessment of the corticospinal motor pathway by transcranial magnetic stimulation, measuring the central motor conduction time from the motor cortex to the muscles.

30 to 45 minutes

Pre-surgical assessment of epilepsy

Complete multidisciplinary assessment aimed at precisely identifying the epileptogenic focus in patients with drug-resistant epilepsy who are candidates for surgery.

Several weeks (staggered assessment)

Intraoperative neurophysiological monitoring

Real-time monitoring of nerve function during surgical procedures involving a neurological risk, making it possible to prevent irreversible nerve damage.

Duration of the surgical procedure (from 2 to 8 hours depending on the type of surgery)

Study of the neuromuscular junction

Exploration of the transmission of the nerve impulse between the nerve and the muscle, essential for the diagnosis of myasthenia and myasthenic syndromes.

30 to 60 minutes
