Attila Losonczy (born 1974) is a Hungarian neuroscientist, Professor of Neuroscience at Columbia University Medical Center.
[1] Losonczy's main area of research is on the relationship between neural networks and behavior, specifically with regard to learning in the hippocampus.
[1] Losonczy and his PhD student Matthew Lovett-Barron uncovered the role of interneurons in fear memory formation in the hippocampus using in vivo imaging and optogenetics.
[2] In 2015, Losonczy and his PhD student Nathan Danielson discovered the role of neurogenesis in the dentate gyrus in memory formation and pattern separation.
[11] This discovery is significant, as anxiety, depression, and posttraumatic stress disorder are thought to be associated with failures in pattern separation.
