Abstract

High-frequency oscillations (HFOs) are characteristics of epileptogenesis and associated to memory impairments. Here, we will describe recent advances in the detection and analysis of HFOs applied to the study of epilepsy and Alzheimer’s disease. We will discuss recent data using large-scale in vivo electrophysiology in different animal models of AD to search for early EEG biomarkers.    

 

Affiliation and short bio

Dr. Christos Lisgaras received his Integrated Master’s Degree in Applied Biology and Technology from the University of Ioannina in Greece and his Ph.D. in Neurophysiology and Neuropharmacology from the same institution He was subsequently trained at the Albert Einstein College of Medicine to investigate post-traumatic electrophysiological (EEG) abnormalities and antiepileptogenic treatments as a part of a preclinical consortium, the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx).

Christos has served on committees at the International League against Epilepsy (ILAE) and he is a founding member of the Young Epilepsy Section. He has been awarded the Herbert H. Jasper Junior Investigator Travel Award and supported by the ILAE, AES, the Alexander S. Onassis Public Benefit Foundation, the Greek National Scholarships Foundation, the Bodossaki Foundation, and the World Hellenic Biomedical Association. His work is also supported by NYU’s Comprehensive Epilepsy Center FACES Pilot Research Grant to advance brain stimulation strategies in temporal lobe epilepsy.
