It's named after Latin for "seahorse," which it resembles. And like the rest of the brain, it's made of neurons. So the human brain has about a hundred billion neurons in it. And the neurons communicate with each other by sending little pulses or spikes of electricity via connections to each other. The hippocampus is formed of two sheets of cells, which are very densely intercon...
