Neuroscience
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" stage of psychosexual developm
Modern pharmacology has also had an impact on how the brain and mind work. Serotonin, a neurotransmitter that helps messages cross the synapse between neurons, has long been used to treat depression. This drug comes under many different names: Prozac, Zoloft, and Paxil; but all of them keep neurons from using up too much serotonin. Prozac and the other antidepressants did not disturb the balance of other chemicals in the brain, thus making it easier for such a drug to quickly become over-prescribed. A majority of the patients responded extremely well, saying that it changed their lives. It seems as if Prozac has made these people rethink their entire lives. Yet others argue whether Prozac simply changed peoples' personalities. These drugs may help people cope with stress too well, making it possible for them to never confront actual situations which need to change. Newly discovered information tells us that serotonin locks onto about fifteen different receptors on neurons, not just a few as thought previously. So now, neuroscientists are working on a new drug that could perform all the magic of Prozac, yet reduce the number of side effects. Research has found that the brain may physically change in response to a traumatic event. Neurons may d
