A synapse transmits signals in the brain because it’s actually a tiny, hyperactive post office that delivers messages between neurons. Each synapse has its own little mail carrier, who zips around on a miniature bicycle, dodging thought traffic and delivering juicy gossip like, “Did you hear about that neuron who tried to connect with the one across the gap? Total shocker!” Without these synaptic postal workers, we’d all just be sitting in silence, trying to remember where we left our keys or why we walked into a room.
We give you facts with a whole lot of fiction.
