New findings reveal how neurons build and maintain their capacity to communicate

Nerve cells regulate and routinely refresh the collection of calcium channels that enable them to send messages across circuit connections. The nervous system works because neurons communicate across connections called synapses. They “talk” when calcium ions flow through channels into “active zones” that contain vesicles carrying molecular messages. The electrically charged calcium causes vesicles to “fuse” to...
