Right Brain, Left Brain? Scientists Debunk Popular Theory Maybe you're "right-brained": creative, artistic, an open-minded thinker who perceives things in subjective terms. Or perhaps you're more of a "left-brained" person, where you're analytical, good at tasks that require attention to detail, and more logically minded. It turns out, though, that this idea of "brained-ness" might be more of a figure of speech than anything, as researchers have found that these personality traits may not have anything to do with which side of the brain you use more. Researchers from the University of Utah found with brain imaging that people don't use the right sides of their brains any more than the left sides of their brains, or vice versa. "It's absolutely true that some brain functions occur in one or the other side of the brain. Anderson and his colleagues, who published their new study in the journal PLOS ONE, looked at brain scans from 1,011 people between ages 7 and 29.
Anthropology Anthropology /ænθrɵˈpɒlədʒi/ is the study of humankind, past and present, that draws and builds upon knowledge from social and biological sciences, as well as the humanities and the natural sciences. Since the work of Franz Boas and Bronisław Malinowski in the late 19th and early 20th centuries, anthropology in Great Britain and the US has been distinguished from ethnology and from other social sciences by its emphasis on cross-cultural comparisons, long-term in-depth examination of context, and the importance it places on participant-observation or experiential immersion in the area of research. In those European countries that did not have overseas colonies, where ethnology (a term coined and defined by Adam F. Origin of the term The term anthropology originates from the Greek anthrōpos (ἄνθρωπος), "human being" (understood to mean humankind or humanity), and -λογία -logia, "study."

- LifeEdited How The Brain Rewires Itself It was a fairly modest experiment, as these things go, with volunteers trooping into the lab at Harvard Medical School to learn and practice a little five-finger piano exercise. Neuroscientist Alvaro Pascual-Leone instructed the members of one group to play as fluidly as they could, trying to keep to the metronome's 60 beats per minute. Every day for five days, the volunteers practiced for two hours. Then they took a test. At the end of each day's practice session, they sat beneath a coil of wire that sent a brief magnetic pulse into the motor cortex of their brain, located in a strip running from the crown of the head toward each ear. The finding was in line with a growing number of discoveries at the time showing that greater use of a particular muscle causes the brain to devote more cortical real estate to it. "Mental practice resulted in a similar reorganization" of the brain, Pascual-Leone later wrote.
Force of habit: Stress hormones switch off areas of the brain for goal-directed behaviour Cognition psychologists at the Ruhr-Universität together with colleagues from the University Hospital Bergmannsheil (Prof. Dr. Martin Tegenthoff) have discovered why stressed persons are more likely to lapse back into habits than to behave goal-directed. The team of PD Dr. Two stress hormones in use In order to test the different stress hormones, the cognition psychologists used three substances – a placebo, the stress hormone hydrocortisone and yohimbine, which ensures that the stress hormone noradrenaline stays active longer. Goal-directed behaviour and habits investigated in the experiment In the experiment, all participants – both male and female – learned that they would receive cocoa or orange juice as a reward if they chose certain symbols on the computer. Combined effect of yohimbine and hydrocortisone As expected, volunteers who took yohimbine and hydrocortisone did not behave goal-directed but according to habit.
Educational psychology Educational psychology is the study of human learning. The study of learning processes, both cognitive and affective, allows researchers to understand individual differences in behavior, personality, intellect, and self- concept. The field of educational psychology heavily relies on testing, measurement, assessment, evaluation, and training to enhance educational activities and learning processes. This can involve studying instructional processes within the classroom setting. Educational psychology can in part be understood through its relationship with other disciplines. It is informed primarily by psychology, bearing a relationship to that discipline analogous to the relationship between medicine and biology. The field of educational psychology involves the study of memory, conceptual processes, and individual differences (via cognitive psychology) in conceptualizing new strategies for learning processes in humans. History Early years Plato and Aristotle
Pareto efficiency Pareto efficiency, or Pareto optimality, is a state of allocation of resources in which it is impossible to make any one individual better off without making at least one individual worse off. The term is named after Vilfredo Pareto (1848–1923), an Italian economist who used the concept in his studies of economic efficiency and income distribution. The concept has applications in academic fields such as economics and engineering. For example, suppose there are two consumers A & B and only one resource X. Pareto efficiency is a minimal notion of efficiency and does not necessarily result in a socially desirable distribution of resources: it makes no statement about equality, or the overall well-being of a society. The notion of Pareto efficiency can also be applied to the selection of alternatives in engineering and similar fields. Pareto efficiency in short It is commonly accepted[by whom?] Weak Pareto efficiency Use in engineering for each i and
Exercise Plus Fasting May Boost Brain's Neurons Forget what you've heard about "brain food"...turns out, the best food for your brain may be none at all. New research on intermittent fasting and exercise show some surprising brain benefits of depriving yourself of calories -- at least occasionally. "We have evidence that exercise and probably intermittent fasting increase the number of mitochondria in neurons," said Mark Mattson, a neuroscientist at the National Institute on Aging in Baltimore. So far, Mattson and other researchers have studied the phenomenon in animals, and are beginning to understand how intermittent fasting in rats and mice can enhance learning and memory, and how it can decrease the risk of those brain functions degenerating. How You Can Be Fit But Not Healthy The basic premise, presented at the Society for Neuroscience annual meeting, is that the stress of fasting and exercise helps the brain adapt and improve the energy flow of neurons. Want to Lose Weight? They'd also undergo the scan in a resting state.
20 Amazing Facts About Your Brain The human brain is amazing and the more I read about it the more fascinated I become with not only it’s limitations, but also it’s immense power. Since I originally wrote the post 30 Amazing Facts About Your Brain I have been on the look out for more amazing tidbits. Here are another 20 for you to wrap your head round, but don’t make the mistake of thinking they don’t apply to you, because they do. 1. However, if you were to pull yours out and stretch out all the folds it would be over 3 feet square. Meet My Wife, Mrs Brownson-Brownson 2. Your brain just loves continuity and it loves familiarity, so even though you may consciously think your partners name had zero to do with you falling in love and it was really their perfectly formed personality, you’d be wrong. 3.

Computer science Computer science deals with the theoretical foundations of information and computation, together with practical techniques for the implementation and application of these foundations History The earliest foundations of what would become computer science predate the invention of the modern digital computer. Blaise Pascal designed and constructed the first working mechanical calculator, Pascal's calculator, in 1642. In 1673 Gottfried Leibniz demonstrated a digital mechanical calculator, called the 'Stepped Reckoner'. He may be considered the first computer scientist and information theorist, for, among other reasons, documenting the binary number system. Although many initially believed it was impossible that computers themselves could actually be a scientific field of study, in the late fifties it gradually became accepted among the greater academic population. It is the now well-known IBM brand that formed part of the computer science revolution during this time. Misc
