Neuroscience Neuroscience is the scientific study of the nervous system.[1] Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. It also exerts influence on other fields, such as neuroeducation[2] and neurolaw. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire science of the nervous system. Because of the increasing number of scientists who study the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientists and educators. History[edit] The study of the nervous system dates back to ancient Egypt. Modern neuroscience[edit] Human nervous system
Is Willpower a Limited Resource Which Can be Cultivated with Exercise? Picture: Robbin Cresswell (PD) “Do what thou wilt shall be the whole of the Law” – Aiwass New developments in biological science suggest your willpower is drawn from a limited supply of chemicals which accumulate in the brain over time. According to Wired willpower is: a measurable form of mental energy that runs out as you use it, much like the gas in your car.Roy Baumeister, a psychologist at Florida State University, calls this “ego depletion,” and he proved its existence by sitting students next to a plate of fresh-baked chocolate-chip cookies. Some were allowed to snack away, others ordered to abstain. If willpower is thought of as a chemical produced by the brain using specific ingredients (such as glucose) it provides a number of insights into its practical use: As Tierney explains, “People with the best self-control aren’t the ones who use it all day long. For the moment these findings are probably best used as an insightful metaphor as opposed to concrete reality.
Berkeley on Biphasic Sleep If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don’t roll your eyes. New research from the University of California, Berkeley, shows that an hour’s nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter. Students who napped (green column) did markedly better in memorizing tests than their no-nap counterparts. (Courtesy of Matthew Walker) Conversely, the more hours we spend awake, the more sluggish our minds become, according to the findings. “Sleep not only rights the wrong of prolonged wakefulness but, at a neurocognitive level, it moves you beyond where you were before you took a nap,” said Matthew Walker, an assistant professor of psychology at UC Berkeley and the lead investigator of these studies. In the recent UC Berkeley sleep study, 39 healthy young adults were divided into two groups — nap and no-nap.
Simplicity Organization makes a system of many appear fewer. The home is usually the first battleground that comes to mind when facing the daily challenge of managing complexity. Stuff just seems to multiply. These typical solutions have mixed results. Concealing the magnitude of clutter, either through spreading it out or hiding it, is an unnuanced approach that is guaranteed to work by the first Law of reduce. However, in the long term an effective scheme for organization is necessary to achieve definitive success in taming complexity. Color: Meaning, Symbolism and Psychology Green occupies more space in the spectrum visible to the human eye and is second only to blue as a favorite color. Green is the pervasive color in the natural world that is an ideal backdrop in interior design because we are so used to seeing it everywhere. The natural greens, from forest to lime, are seen as tranquil and refreshing, with a natural balance of cool and warm (blue and yellow) undertones. Green is considered the color of peace and ecology. However, there is an "institutional" side to green, associated with illness or Government-issued that conjure up negative emotions as do the "slimy" or bilious greens. How the color green affects us physically and mentally * Soothing * Relaxing mentally as well as physically * Helps alleviate depression, nervousness and anxiety * Offers a sense of renewal, self-control and harmony For more information see "All About the Color Green"
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. So here’s my top 10 list of what you can learn practically from the psychological research discussed here recently. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. The Neuroscience of Decision Making In an attempt to put matter over mind, researchers are beginning to decipher what exactly is happening in our brains when we are making decisions. Our thoughts, though abstract and vaporous in form, are determined by the actions of specific neuronal circuits in our brains. The interdisciplinary field known as “decision neuroscience” is uncovering those circuits, thereby mapping thinking on a cellular level. Although still a young field, research in this area has exploded in the last decade, with findings suggesting it is possible to parse out the complexity of thinking into its individual components and decipher how they are integrated when we ponder. Eventually, such findings will lead to a better understanding of a wide range of mental disorders, from depression to schizophrenia, as well as explain how exactly we make the multitude of decisions that ultimately shape our destiny. The following is an edited transcript of the teleconference. C. WANG: Yes.
Why sleep deprivation can make you unethical - Post Leadership Posted at 10:21 AM ET, 05/13/2011 May 13, 2011 02:21 PM EDT TheWashingtonPost New research shows that sleep deprivation has worse effects than just the occasional mistake or error—and can cost organizations just as much, if not more. (MATT MCCLAIN - THE WASHINGTON POST) As we all know, sleep deprivation can lead to exhaustion-fueled mistakes in the workplace, whether they be a simple typo in a quarterly report or life-threatening errors while operating machinery. (Or as the FAA discovered recently, embarrassing front-page headlines about workers napping on the job.) In a forthcoming paper in the Academy of Management Journal, highlighted recently in the Financial Times, Michael Christian of the University of North Carolina’s Kenan-Flagler Business School and Aleksander Ellis of the University of Arizona’s Eller College of Management studied sleep-deprived nurses and students who’d pulled all-nighters in a sleep lab. How does this happen? And why does this matter for leaders?

An On-Off Switch for Anxiety With the flick of a precisely placed light switch, mice can be induced to cower in a corner in fear or bravely explore their environment. The study highlights the power of optogenetics technology—which allows neuroscientists to control genetically engineered neurons with light—to explore the functions of complex neural wiring and to control behavior. In the study, Karl Deisseroth and collaborators at Stanford University identified a specific circuit in the amygdala, a part of the brain that is central to fear, aggression, and other basic emotions, that appears to regulate anxiety in rodents. “We want to conceptualize psychiatric disease as real physical entities with physical substrates,” says Deisseroth. The researchers engineered mice to express light-sensitive proteins in specific cells in the amygdala that send out neural wires, known as axons, to different substructures.
The Essential Psychopathology Of Creativity Andrea Kuszewski If we could identify a gene for creativity, let's call it the "creativity gene", you would be hard pressed to find very many people who would consider it a "negative gene" or a hazard to possess or carry. But what if, purely hypothetically, we could identify a gene for Schizophrenia? Or Bipolar Disorder? Or Depressive Disorder? Or ADHD? The very traits that make someone creative, passionate, and likely to achieve a high degree of success in their domain, are the same traits that define psychological disorders such as Bipolar Disorder, Schizophrenia, and ADHD. An article in the NY Times titled, "Just Manic Enough: Seeking Perfect Entrepreneurs", described individuals that were unnaturally creative, passionate, energetic, charismatic, and those most sought-after by venture capitalists as "hypomanic". Now, I don't know how many of you creative-types out there began to panic when you started reading this list of defining criteria, but I know I did. I say yes.
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.
Neuroscientists reveal magicians' secrets - Technology & science - Science - LiveScience NEW YORK — There is a place for magic in science. Five years ago, on a trip to Las Vegas, neuroscientists Stephen Macknik and Susana Martinez-Conde realized that a partnership was in order with a profession that has an older and more intuitive understanding of how the human brain works. Magicians, it seems, have an advantage over neuroscientists. "Scientists have only studied cognitive illusions for a few decades. She and Macknik, her husband, use illusions as a tool to study how the brain works. After their epiphany in Las Vegas, where they were preparing for a conference on consciousness, the duo, who both direct laboratories at the Barrow Neurological Institute in Arizona, teamed up with magicians to learn just how they harness the foibles of our brains. The psychological concepts behind illusions are generally better understood, but they treat the brain as something of a black box, without the insight into brain activity or anatomy that neuroscience can offer, they write.
Ten Virtues for the Modern Age The Virtues Project comes as a response to the wave of discussion and feedback that followed the publication of my book, Religion for Atheists, and a growing sense that being virtuous has become a strange and depressing notion, while wickedness and evil bask in a peculiar kind of glamour. My ultimate aim for the project is that it ignites a vital conversation around moral character to increase public interest in becoming more virtuous and connected as a society. In the modern world, the idea of trying to be a ‘good person’ conjures up all sorts of negative associations: of piety, solemnity, bloodlessness and sexual renunciation, as if goodness were something one would try to embrace only when other more difficult but more fulfilling avenues had been exhausted. Throughout history, societies have been interested in fostering virtues, in training us to be more virtuous, but we're one of the first generations to have zero public interest in this. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
