At the BCI & Neurotechnology Spring School 2025, this presentation explored advanced techniques for functional brain mapping using electrocorticography (ECoG), high-gamma activity, and cortico-cortical evoked potentials (CCEPs). The session demonstrated how these technologies help identify critical brain regions and neural networks for safer neurosurgical procedures and a deeper understanding of brain function.
cortiQ is g.tec’s rapid cortical mapping platform designed for epilepsy surgery, brain tumor resection, and neuroscience research. By combining real-time high-gamma mapping, electrical cortical stimulation (ECS), cortico-cortical evoked potentials (CCEPs), and somatosensory evoked potentials (SEP), cortiQ enables precise localization of motor, sensory, and language areas while minimizing surgical risks.
🔬 Topics covered in this presentation
• Electrocorticography (ECoG) and stereo-EEG
• High-gamma brain mapping
• Cortico-cortical evoked potentials (CCEPs)
• Electrical cortical stimulation (ECS)
• Somatosensory evoked potentials (SEP)
• Functional connectivity and cortical networks
• Language mapping and motor mapping
• Brain tumor surgery planning
• Epilepsy surgery planning
• Real-time brain activity visualization
• White matter exploration and connectivity analysis
• Neurosurgical decision support
🧠 Why Functional Brain Mapping Matters
Accurate identification of eloquent cortex regions is essential for preserving critical brain functions during neurosurgical procedures. cortiQ enables clinicians to visualize functional brain activity in real time while patients perform tasks such as speaking, listening, calculating, or moving their limbs. The resulting maps help neurosurgeons identify areas responsible for language, movement, sensation, and cognition before tissue resection.
Unlike traditional approaches that may be time-consuming or trigger seizures, high-gamma mapping with cortiQ provides rapid, objective, and highly precise information about cortical function. Integrated ECS and CCEP modules further validate findings and reveal connectivity between brain regions.
🏥 Applications
• Epilepsy surgery
• Brain tumor surgery
• Awake brain surgery
• Stereo-EEG investigations
• Functional connectivity research
• Language and motor cortex mapping
• Neuroscience and neurotechnology research
• Brain-computer interface (BCI) research with ECoG
This session highlights how real-time cortical mapping, advanced neurophysiology, and machine learning are transforming modern neurosurgery and improving patient outcomes.
