This year 140 students from all over the world (France, Italy, Russia, Mexico, Taiwan…) gathered at CIRM on the Luminy Campus for the 4th ILCB summer school. They were offered a variety of introductory and advanced courses that reflect the expertise of our Institute, including Language and Cognition, Neuroscience, Statistics and Machine Learning, etc. Students also realized how much fun science can be! The keynote by cognitive neuroscientist Prof. Sophie Scott’s on how and why people laugh was intriguing, inspiring, and… irresistible! Socializing on campus or at the Calanques National Park next door topped a wonderful week to refresh or reinforce our knowledge and know-how about language, communication, and the brain.
