What our clients say

"The performance of the HFO detector is really good compared with other detectors I have tested. It offers many useful tools that are not available in other software. It is great collaborating with Avrio MedTech, and I look forward to all our future achievements together."

Christos LISGARASResearch Assistant Professor, Department of Psychiatry
New York University Grossman School of Medicine, NY, USA

"Integrating Halyzia® into our portfolio represents a significant milestone in our commitment to innovation. Our customers rely on FHC not only for world‑class hardware, but also for powerful, modern analytical software. Halyzia® delivers exactly that, an intuitive, scalable software that elevates the way clinicians and researchers interact with SEEG data."

Cosmin SERBANCEO of FHC, Inc.

"Halyzia® is a very nice viewer. We can see that it was designed by and for clinicians. Halyzia development was clearly driven by clinicians for smart detection and quantification of spikes and HFOs in intracranial EEG signals."

Gilles HUBERFELDNeurologist, Hôpital Fondation Adolphe de Rothschild, Paris, France

"Halyzia® truly streamlines the analysis of clinical SEEG data, enabling effortless detection and quantification of HFOs and spikes. I particularly appreciate its user-friendly and intuitive interface, which also offers multiple visualization features—making it an invaluable tool for clinicians and researchers."

Pr Jonathan CUROTNeurologist expert on epilepsy, Toulouse University Hospital
Researcher at the Brain and Cognition Research Center (CerCo, CNRS), Toulouse, France

"Halyzia® is the main tool I use for my work with data from multiple centers. The software is fast and makes data review and interpretation accessible without requiring programming experience. I also provide regular feedback to Avrio MedTech through testing and regular use, and I value their responsiveness and commitment to improving the software based on user input."

Marina INYUTINAResearch engineer at the Brain and Cognition Research Center (CerCo, CNRS), Toulouse, France

"Halyzia® provides an intuitive and powerful entry ramp to powerful and flexible local field potentials (LFP) analysis for users of all skill levels. It is simple enough for novice signal scientists while encompassing the depth required by experienced ones."

Matt STEADFounder of Dark Horse Neuro & co-founder of Neuro Health Collective
