Analysing intracranial EEG recordings for epilepsy research
Surgery for drug-resistant epilepsy requires locating the brain region responsible for seizures. Brain recordings generate large, complex datasets that neurologists can only partly review without automated tools, leaving potentially useful information unexplored.
Avrio MedTech provides Halyzia software to visualise and quantify intracranial EEG recordings for research. Automatic biomarker detection, expert review and data-quality tools help researchers investigate epilepsy signals in one workflow.
What stands out about Avrio MedTech
FHC announced a partnership in March 2026 to distribute Halyzia, adding a neuroscience equipment partner as a sales route.
Spun out of CNRS/CerCo and ENAC research, with Toulouse Tech Transfer supporting maturation of the technology.
Co-founder Karine Seymour previously co-founded XPRIM, a medical-imaging software distributor sold to McKesson France.
Received Bpifrance support through the Bourse French Tech Emergence programme after incorporation.
Works with Toulouse University Hospital clinicians, engineers and researchers on product design, validation and deployment.
Co-founder Emmanuel Barbeau is a CNRS research director with a neuroscience PhD and expertise in epilepsy and electrophysiology.
