The brain has the unique capacity to process information and translates it into behavior. To increase our understanding of brain function, we investigate functional and structural connectivity in the brain by using electrophysiology and imaging techniques. We study how synaptic strength and network activity are changed from developmental stages to the aged brain. In addition, we investigate how dysfunction in cellular and network activity contributes to brain disorders. To educate students on the fundamental principles of brain function, we organize a master track called “Physiology of Synapses and Networks" (PSN).
