Every time a neurone sends a signal - to move a muscle or form a memory, for example - tiny membrane-bound compartments, called vesicles, dump neurotransmitters into the synapse between the cells. Researchers report that this process, which is fundamental to the workings of the nervous system, relies on a simple mechanical reality: Tension in the axon of the presynaptic neurone is required...
