Behavioral neuroscience Behavioral neuroscience, also known as biological psychology,[1] biopsychology, or psychobiology[2] is the application of the principles of biology (in particular neurobiology), to the study of physiological, genetic, and developmental mechanisms of behavior in humans and non-human animals. It typically investigates at the level of neurons, neurotransmitters, brain circuitry and the basic biological processes that underlie normal and abnormal behavior. Often, experiments in behavioral neuroscience involve non-human animal models (such as rats and mice, and non-human primates) which have implications for better understanding of human pathology and therefore contribute to evidence-based practice. History[edit] Behavioral neuroscience as a scientific discipline emerged from a variety of scientific and philosophical traditions in the 18th and 19th centuries. Other philosophers also helped give birth to psychology. Relationship to other fields of psychology and biology[edit]
BrainMind.net When hallucinations follow depth electrode or cortical stimulation, much of the material experienced is very dream-like (Gloor 1990, 1992; Halgren et al., 1978; Malh et al., 1964; Penfield & Perot 1963) and consists of recent perceptions, ideas, feelings, and other emotions which are similarly illusionary and dream-like. Indeed, the right amygdala, hippocampus, and the right hemisphere in general (Broughton, 1982; Goldstein et al., 1972; Hodoba, 1986; Humphrey & Zangwill, 1961; Kerr & Foulkes, 1978; Meyer et al. 1987) also appear to be involved in the production of deam imagery as well as REM sleep (chapter 10). For example stimulation of the amygdala triggers and increases ponto-geniculo-occipital paradoxical activity during sleep (Calvo, et al. 1987), which in turn is associated with REM and dreaming. The Right Hemisphere & Dreams. Forgotten Dreams. Most individuals, however, have difficulty recalling their dreams.
The Dark Side of Oxytocin, the Hormone of Love - Ethnocentrism Yes, you knew there had to be a catch. As oxytocin comes into sharper focus, its social radius of action turns out to have definite limits. The love and trust it promotes are not toward the world in general, just toward a person’s in-group. Oxytocin turns out to be the hormone of the clan, not of universal brotherhood. Psychologists trying to specify its role have now concluded it is the agent of ethnocentrism. A principal author of the new take on oxytocin is Carsten K. In a report published last year in Science, based on experiments in which subjects distributed money, he and colleagues showed that doses of oxytocin made people more likely to favor the in-group at the expense of an out-group. These nationalities were chosen because of a 2005 poll that showed that 51 percent of Dutch citizens held unfavorable opinions about Muslims, and other surveys that Germans, although seen by the Dutch as less threatening, were nevertheless regarded as “aggressive, arrogant and cold.” In Dr. Dr.
10 Practical Uses For Psychological Research in Everyday Life | People love to give each other advice. The web is full to bursting with all types of pseudo-psychological advice about life. The problem is, how much of this is based on real scientific evidence? Well, here on PsyBlog we’ve got the scientific evidence.

The answer quite often is because of other people — something social psychologists have comprehensively shown. Each of the 10 brilliant social psychology experiments below tells a unique, insightful story relevant to all our lives, every day.

The Ten Most Revealing Psych Experiments Psychology is the study of the human mind and mental processes in relation to human behaviors - human nature. Due to its subject matter, psychology is not considered a 'hard' science, even though psychologists do experiment and publish their findings in respected journals. Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble. That's something. 1. The Robbers Cave Experiment is a classic social psychology experiment conducted with two groups of 11-year old boys at a state park in Oklahoma, and demonstrates just how easily an exclusive group identity is adopted and how quickly the group can degenerate into prejudice and antagonism toward outsiders. Researcher Muzafer Sherif actually conducted a series of 3 experiments. 2. The prisoners rebelled on the second day, and the reaction of the guards was swift and brutal. 3. 4. 5. 6. 7. 8. 9. 10.
The Limits of Intelligence Santiago Ramón y Cajal, the Spanish Nobel-winning biologist who mapped the neural anatomy of insects in the decades before World War I, likened the minute circuitry of their vision-processing neurons to an exquisite pocket watch. He likened that of mammals, by comparison, to a hollow-chested grandfather clock. Indeed, it is humbling to think that a honeybee, with its milligram-size brain, can perform tasks such as navigating mazes and landscapes on a par with mammals. A honeybee may be limited by having comparatively few neurons, but it surely seems to squeeze everything it can out of them. At the other extreme, an elephant, with its five-million-fold larger brain, suffers the inefficiencies of a sprawling Mesopotamian empire. Signals take more than 100 times longer to travel between opposite sides of its brain—and also from its brain to its foot, forcing the beast to rely less on reflexes, to move more slowly, and to squander precious brain resources on planning each step.

Researcher: Dopamine Not About Pleasure (Anymore) John Salamone, professor of psychology, at his office. (Peter Morenus/UConn Photo) To John Salamone, professor of psychology and longtime researcher of the brain chemical dopamine, scientific research can be very slow-moving. “It takes a long time for things to change in science,” he says. Salamone, a UConn Board of Trustees Distinguished Professor, has spent most of his career battling a particular long-held scientific idea: the popular notion that high levels of brain dopamine are related to experiences of pleasure. In the early 1980’s, explains Salamone, the National Institute on Drug Abuse put out a call for research on the neurological basis for drug abuse and addiction. The research that ensued built support for the idea that when the brain produced elevated amounts of dopamine, it was accompanied by perceptions of pleasure. But over time, Salamone’s studies and those of others started revealing problems. He points out that new ideas in science are traditionally met with criticism.
