In the past, when people had psychological problems, neuroscientists would often wrongly jump to the conclusion that something in the persons' past was to blame. Nowadays, scientists know more than ever about the growing field of neuroscience. In "The Brain-Mind Connection: A Quarter Century of Neuroscience , Beth Horning discusses the future possibilities for this growing field. According to recent statistics, "over 90 percent of the neuroscientists who ever lived are living now (59), and more has been accomplished in the field during the past twenty years than the past two hundred.
Until recently, the brain could only be studied under extreme situations of illness when symptoms readily appeared. The public lacked interest in matters of the mind, which made neuroscience a difficult field to research. Not until the arrival of the positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) did the public give a second thought to brain activity. These tools gave scientists a way to visually track brain activity. PET scans, for example, helped disprove the theory that obsessive-compulsive disorder (OCD) is a psychological illness where a patient is fixated to the "anal
