Neurons, Hormones, and the Brain Studying the Brain To examine the brain’s functions, researchers have to study a working brain, which means they can’t use cadavers. Invasive studies, in which researchers actually put instruments into the brain, can’t be done in humans, though they can be done occasionally during medically necessary brain surgery. Researchers usually use invasive techniques in animal studies. There are two main types of invasive animal studies: Lesioning studies: Researchers use an electrode and an electric current to burn a specific, small area of the brain. Electric stimulation of the brain: Researchers activate a particular brain structure by using a weak electric current sent along an implanted electrode. Because they cannot use such invasive techniques on humans, researchers study human brains in two ways: They examine people with brain injuries or diseases and see what they can and can’t do. They use
