Document Summary
Brain regions and neurotransmitters are intimately involved in emotions. Sleeping sickness (encephalitis lethargica) made people act like zombies until they got a dose of l-dopa. They began to act spontaneously with emotion, passion, appetite and sexual desires. Neuroimaging: machine monitors biochemical events in a series of conceptual slices through a person"s brain, while computer takes info and constructs images of the brain to show where it is most active. Positron emission tomography (pet) and functional magnetic resonance imaging (fmri) Neuroscientists study emotional effects of accidental damage to the brain while others have made lesions deliberately in brains of animals. Neurophysiologists have stimulated parts of the brain electrically and pharmacologically stimulated parts of the brain with chemical mechanisms of neurons. One can also record the electrical activity of single neurons. Left to right: spinal cord, cerebellum, pineal gland, cerebrum, corpus callosum, thalamus, hypothalamus, pituitary gland, midbrain, pons, medulla.
