Researchers in China are advancing brain-computer interface (BCI) technology by implanting computer chips into the brains of people with disabilities, achieving promising results. The Chinese Institute for Brain Research (CIBR) in Beijing and its affiliated start-up NeuCyber are leading these efforts. BCI technology acts as a bridge between the mind and machines, transforming human-device interaction and opening new frontiers in neuroscience and the treatment of neurological disorders. Similar developments are occurring internationally, with Germany's neurotechnology firm CorTec also contributing to the field. Meanwhile, scientific studies continue to explore various aspects of brain function and neurodegeneration, including the role of microglial TREM2 in neuronal degeneration and regeneration, the regulation of GABAergic neurogenesis by microglia in the prenatal human brain, and the development of human neuron-on-chip platforms to monitor neuronal injury responses. Additionally, researchers have created multiregional cerebral organoids that mimic key human brain functions, further advancing neuroscience research.
