We held “Winter Workshop on Neural Circuitry” with five other labs on Feb 19-20, 2019 in Riverheim, Gapyeong. Participated labs are the labs of Chihye Chung (Konkuk U), Daesoo Kim (KAIST), Greg Suh (KAIST), Hyosang Lee (DGIST) and Han Kyung Choe (DGIST), who are actively engaged with research in the neural circuit field. We had exciting presentation, discussion and networking times.
