At the BCI & Neurotechnology Spring School 2025, this presentation explored advanced real-time brain mapping techniques based on high-gamma and ultra-high gamma neural activity. The session demonstrated how high-frequency brain signals recorded with electrocorticography (ECoG) and stereo-EEG can be used to identify functional brain regions with exceptional precision during neurosurgical procedures and neuroscience research.
cortiQ is g.tec’s rapid cortical mapping platform that enables real-time visualization of brain activity during language, motor, sensory, and cognitive tasks. By analyzing high-gamma activity directly from the cortex, cortiQ helps neurosurgeons localize eloquent brain regions before tissue resection, improving surgical precision and reducing the risk of neurological deficits.
🔬 Topics covered in this presentation
• High-gamma mapping
• Ultra-high gamma brain activity
• Electrocorticography (ECoG)
• Stereo-EEG (sEEG)
• Real-time functional brain mapping
• Language mapping
• Motor cortex mapping
• Sensory cortex mapping
• Epilepsy surgery planning
• Brain tumor surgery planning
• Electrical cortical stimulation (ECS)
• Cortico-cortical evoked potentials (CCEP)
• Brain connectivity analysis
• Neurosurgical decision support
🧠 Why High-Gamma Mapping?
High-gamma activity is one of the most powerful biomarkers for identifying active brain regions during specific tasks. When a patient speaks, moves, listens, calculates, or processes visual information, high-gamma oscillations increase in the corresponding cortical areas. cortiQ analyzes these signals in real time and projects the results directly onto 2D and 3D brain models, providing immediate feedback for clinicians and researchers.
Compared to traditional mapping techniques, high-gamma mapping offers rapid, objective, and highly accurate localization of functional cortex. Combined with integrated ECS, SEP, and CCEP modules, cortiQ provides a comprehensive platform for understanding both cortical function and brain network connectivity.
🏥 Applications
• Epilepsy surgery
• Brain tumor surgery
• Awake brain mapping
• Functional connectivity research
• Language and speech mapping
• Motor and sensory mapping
• Neurotechnology research
• ECoG-based brain-computer interfaces (BCIs)
This session highlights how real-time analysis of high-frequency neural activity is advancing neurosurgery, neuroscience, and our understanding of human brain function.
