Comprehensive World Brain Mapping Course-George Samandouras, MD, FRCS

Video Transcription

Video Summary

The speaker is a neurosurgeon who practices at the National Hospital for Neurology and Neurosurgery in Queens Square. They discuss their anesthetic technique, which has transitioned from sleep-awake to awake throughout. They explain how they perform a circumferential scalp block using a small gauge needle and local anesthetics. They also discuss the instruments they use and the settings they modify, such as the current output on the Ultima Stimulator. The speaker emphasizes the importance of knowing the anatomy and tracts of the brain, as well as understanding the behavior of different tissues during surgery. They highlight their approach to removing insula gliomas and gliomas affecting the genu of the corpus callosum. The speaker also discusses the use of intraoperative MRI scans and the incorporation of fMRI, DTI, and TMS into neuro-navigation systems. They touch on the subject of plasticity and caution about the lack of agreement among researchers regarding which tracts to stimulate and how. They mention their work on segmenting the brain for mapping purposes and express the importance of standardized mapping. The speaker concludes by thanking their team and promoting their annual course in London.
