Shedding light on neural activities with LEDs

Living in a group has clear benefits. As a member of a societal group, one can share resources with the others, seek protection from predators, and forage in an efficient manner. In a 2020 paper published in Science Advances, the neuroscientist Jee Hyun Choi and her student Jisoo Kim of the Brain Science Institute in the Korea Institute of Science and Technology (KIST) argue that there are much more stories about the advantages of group living and social behaviors to the mammalian brain yet to be discovered. Their research was conducted using CBRAIN (Collective Brain Research Aided by Illuminating Neural activity), a unique neuro-telemetric device equipped with LED lights, which enables the measurement and real-time analysis of collective brain activities.
