- Scalp
- Corticography
SEPs – Somatosensory evoked potentials
- Upper extremities: median and ulnar nerve
- Brainstem

- Lower extremities: common peroneal and posterior tibial nerve
- Pelvic: Pudendal Nerve
Evoked EMGs – Electromyography
- Upper/lower extremity
- Cranial nerves (CNs III, IV, V, VI, VII, IX, X, XI, and XII)
TcMEPs – Transcranial Motor Evoked Potentials
- Upper extremities

- Brainstem
- Direct CAPs (CN VIII and peripheral nerves)
Data samples of the various modalities used to monitor patients:
- EMG
- SSEP
- EEG
- MEP
- CMP
- BAEP
- Below is an example irritation of spontaneous EMG of the left and right recurrent laryngeal nerve being monitored during a thyroidectomy.
- Shown below is SEP data of the median nerve (MSP) observed during a carotid endarterectomy. Changes can be seen in the responses from the left median nerve at the time of clamping of the common carotid artery.
- An example of filtered EEG (left) and spectral EEG (right) during a carotid endarterectomy is pictured here. A decrease in cortical activity in the left hemisphere occured when the left common carotid artery was clamped during the procedure.
- Below is sample data of MEP collected during a craniotomy (left) and a shoulder arthroplasty (right) where the motor cortex is stimulated and potentials are recorded from muscle groups.
- Below is a sample of CMP data from a posterior lumbar fusion. As the pedicle screws are stimulated, evoked responses are obtained in several lower extremity muscle groups.
- This is an example of data collected from a BAEP test monitoring CN VIII, during a retromastoid craniotomy for microvascular decompression of the trigeminal nerve.
