Attila Losonczy received the MD degree from the Medical School, University of Pécs in 1999, and has been a member of the Kavli Institute for Brain Science since 2010. In 2011, Losonczy was named a Searle Scholar. In 2013, he was awarded the NARSAD Young Investigator Award. Losonczy was awarded the BRAIN Initiative Award by the National Institute of Health in two consecutive years, 2014 and 2015. Attila’s research program is aimed at understanding how mammalian cortical circuits mediate learning and formation of declarative memories – our repository of acquired information of people, places, objects and events. His laboratory uses functional imaging, electrophysiology, behavioral analysis, manipulation, and computational modeling to dissect the functional role of hippocampal excitatory, inhibitory and modulatory neural circuits in mnemonic functions. Subsequent work – combining in vivo functional imaging and perturbations of genetically-specified neurons during behavior – has redefined our understanding of hippocampal circuit function. For instance, they characterized the type of information carried by subcortical inputs to the hippocampus at a single synapse-level (Kaifosh et al., Nature Neuroscience, 2013), and they dissected the roles of hippocampal inhibitory circuits in navigation and learning (Lovett-Barron et al., Science, 2014, Lee et al. Neuron, 2014; Basu et al., Science 2016).
