microelectrode recording

microelectrode recording

A high-precision technique used in functional neurosurgery to delineate tissue that can be excised.

Method
A small electrode is guided into a target via a hole in the skull; the activity of clusters of individual neurons is then recorded to delineate the good from the bad.

SNI's comprehensive diagnostic and surgical capabilities include: -- Integrated, GPS-like guidance systems built into every OR that help surgeons navigate in critical areas of the brain during operations -- Intraoperative MRI and CT scanners and 3-D angiography that provide vital images during surgery -- Brain-mapping capabilities to identify areas of critical brain function through microelectrode recordings of brain tissue -- Interventional neuroradiology techniques to block blood flow to tumors or blood-vessel malformations prior to surgery, place stents (small wire mesh tubes used for keeping vessels open) in narrowed brain arteries and repair cerebral aneurysms
With microelectrode recordings, more penetrations of the brain have to be made and this increases the risk of intracranial hemorrhage.
