Cracking the Code of Neurotransmission The brain’s ability to transmit signals rapidly hinges on the precise choreography of synaptic vesicle exocytosis. For decades, scientists debated whether vesicles simply “kiss” the presynaptic membrane and retreat (kiss-and-run) or fully collapse to release their neurotransmitters. A groundbreaking study from the University of Science and Technology of China (USTC),…
