Summary

Functional MRI (fMRI) successfully identified and monitored the mirror neuron system (MNS) in a patient with a premotor brain lesion. Post-surgery, improved MNS activity correlated with enhanced motor imitation skills.

Neurosurgery

Background:

Brain mapping is crucial for optimizing functional outcomes in neurosurgery.
The mirror neuron system (MNS) plays a key role in action understanding and imitation.
No prior studies have investigated MNS function perioperatively in patients with brain lesions.

Observation:

A 19-year-old female with a premotor cavernous angioma and impaired hand movement imitation underwent specialized fMRI.
The fMRI protocol involved observing and executing simple finger movements (precision grasping).
fMRI scans were conducted pre- and post-surgery to assess MNS activity.

Findings:

The fMRI protocol effectively identified MNS regions.
MNS regions were preserved during the surgical procedure.
Postoperative fMRI showed improved MNS activation, correlating with better hand movement imitation.

Implications:

This fMRI protocol facilitates straightforward identification and preservation of the MNS during surgery.
Enhanced MNS activity post-surgery may indicate recovery of motor functions.
This approach offers potential for improved neurosurgical planning and patient outcomes.
