Without synapses, your neurons wouldn't be able to communicate and your brain would be little more than a ball of meat. Exactly what synapses look like has been a mystery until now, and it turns out that even though their job is simple, they're complicated as hell.
Just how complex is your noggin? Pretty damn complex, according to researchers at Stanford. Their new imaging technique discovered that synapses are actually more like individual microprocessors than simple on/off switches, and your brain has hundreds of trillions of them.
