If the tiniest thing goes wrong with a particular connection - maybe something misfires, or a certain neural pathway is blocked - things can fall apart very quickly. And, oddly enough, even without any injuries or structural malfunctions, the human brain can get weird all…

Our brains hum with electrical activity. Brain waves created by the coordinated firing of huge collections of nerve cells pinball around the brain. The waves can ricochet from the front of the brain to the back, or from deep structures all the way to the scalp and then back again. Called neuronal oscillations, these signals…
