A liver cell walks into a bar.......and orders a gin and tonic. The bartender says with a sneer, "We don't serve liver cells here." The liver cell replies: "Oh, yeah? Well, what about that cell over there?" and points to a neuron lounging on a bar stool nearby. Says the bartender: "What about her? That's a brain cell. She's got connections."
Yes, a neuron does indeed have connections. Lots of them. And they're called synapses. With close to 100 billion neurons, each of which can make as many as 1000 connections, there are estimated to be trillions of synapses in the human brain. That's more stars than there are in the Milky Way. And it's more than 500 cups of sand (assuming 20 grains of sand line up to 1 cm, and a cup = 250 ml).
Professor Sreeganga Chandra broke down this enormously complicated topic for Tilde Cafe attendees.
