Neurophysiology

Cerebral Blood Flow:

Director: David Liebeskind, MD

Provides inpatient and outpatient cerebral blood flow studies for patients with acute stroke, subarachnoid hemorrhage, arteriovenous malformations, or traumatic brain injury: 1. Transcranial doppler (TCD): Non-invasive assessment of blood flow velocity in the basal cerebral arteries. 2. Xenon-133 Assessment of cerebral perfusion

Electroencephalography (EEG):

Director: Marc R. Nuwer, MD, PhD Phone: 310-825-0177

Provides specialized diagnostic testing of epilepsy and focal brain disturbances, space-occupying lesions, and vascular disorders. 1. Ambulatory EEG monitoring (awake and asleep) 2. Computer EEG analysis (brain mapping) 3. Specialized ICU and OR monitoring

Electromyography (EMG) and Nerve Conduction Studies (NCS):

Director: Perry Shieh, MD, PhD Phone: 310-825-7266

Provides needle EMG tests of motor and sensory nerve conduction for patients with disorders of muscle and peripheral nerve. Single fiber EMG for special cases.

Electronystagmography (ENG):

Phone: 310-825-5910

Provides computer assisted electronystagmography and rotational testing to evaluate pathologic nystagmus, vestibulo-ocular reflex function, and visual ocular control in patients with dizziness and balance problems.

Evoked Potential (EP):

Director: Marc R. Nuwer, MD, PhD Phone: 310-825-0177

Uses special techniques related to visual and somatosensory pathways, intra-operative monitoring, inpatient and outpatient audiometry for evaluation of hearing in high-risk newborns, and cortical evoked potential mapping.

Sleep Laboratory:

Director: Alon Y. Avidan, MD, MPH Phone: 310-267-5337
