01 — What we do

The nervous system, watched over in real time.

During complex surgery, neural structures can be placed at risk long before any visible sign appears. Our scientific personnel continuously track the function of the brain, spinal cord and peripheral nerves — giving your surgical team immediate, actionable feedback when it matters most.

By combining multiple monitoring modalities in each case, we build a more complete and more accurate picture of neural integrity, from incision to closure.

02 — Monitoring modalities

Many techniques. One continuous picture.

Multimodal monitoring enhances accuracy — each technique interrogates a different pathway, and together they leave far fewer blind spots. Below are some of our core modalities; we select and combine techniques to suit each procedure and patient.

EEG

Electroencephalography

Continuous recording of cortical electrical activity to track cerebral function and perfusion.

EMG

Electromyography

Spontaneous and triggered recordings from muscles to detect nerve root and cranial nerve irritation.

SSEP

Somatosensory Evoked Potentials

Assessing the integrity of the sensory pathways from the limbs through the spinal cord to the cortex.

MEP

Motor Evoked Potentials

Transcranial stimulation to verify the function of the descending motor pathways in real time.

D-Wave

Direct Wave Recording

Recording of the descending corticospinal volley via an epidural or subdural electrode — a direct measure of motor tract integrity, particularly valuable in intramedullary spinal cord surgery.
