Phys Ed: How Muscle Workouts May Boost Brainpower - NYTimes.com
The researchers "decided to study “fake” exercise instead, using two specialized drugs that had been tested several years ago by scientists at the Salk Institute in San Diego. The drugs had been shown to induce the same kinds of changes in sedentary animals’ muscles that exercise would cause, so that even though the mice didn’t exercise, they physiologically responded as if they had. ... After a week of receiving either of the two drugs (and not exercising), the mice performed significantly better on tests of memory and learning than control animals that had simply remained quiet in their cages. ...The results, published in the journal Learning and Memory, showed that the drugged animals’ brains also contained far more new neurons in brain areas central to learning and memory than the brains of the control mice, an effect found by microscopic examination."

Left Brain Hemisphere Also Plays Big Part In Creative Thinking, Study Shows
"... a new study shows that while creativity is largely a right-brained task, the left hemisphere of the brain plays a part, too.
Researchers from the University of Southern California published a study in the journal Social Cognitive and Affective Neuroscience showing that the left brain is a crucial supporter of the right brain for creative tasks."

When Gaming Is Good for You - WSJ.com
"Videogames can change a person's brain and, as researchers are finding, often that change is for the better. A growing body of university research suggests that gaming improves creativity, decision-making and perception. The specific benefits are wide ranging, from improved hand-eye coordination in surgeons to vision changes that boost night driving ability."

"People who played action-based video and computer games made decisions 25% faster than others without sacrificing accuracy, according to a study. Indeed, the most adept gamers can make choices and act on them up to six times a second—four times faster than most people, other researchers found. Moreover, practiced game players can pay attention to more than six things at once without getting confused, compared with the four that someone can normally keep in mind, said University of Rochester researchers."

One of the downsides: "Brain scans show that violent videogames can alter brain function in healthy young men after just a week of play, depressing activity among regions associated with emotional control, researchers at Indiana University recently reported."

Jonah Leher On The Three Types Of Creativity And How Brainstorming Doesn't Work | Fast Company
Interview with Jonah Lehrer.
"... there are probably three neurologically distinct forms of creativity. One is when you have these moments of insight that come out of the blue--when you have epiphanies in the shower. Those seem to come from the part of the brain that's involved in things like the interpretation of metaphors and the processing of jokes. Another form is really working hard at solving a problem--it's not nearly as fun as having an epiphany, but it's just as important. The last form is spontaneous improvisation--what Miles Davis did."

Book Review: Guitar Zero - WSJ.com
Brain plasticity applies from cradle to grave. This is a book review of the 'Guitar Zero' book. by cognitive psychologist Gary Marcus. "Mr. Marcus discovers that "the evidence for critical periods is surprisingly weak." It is not that critical periods (when the brain is especially plastic) do not exist. They do, but they vary. The science shows that, at least for learning a language, we don't suddenly lose our plasticity and ability to learn at the end of the critical period. The falloff is often gradual. Relatedly, complex activities such as language and music involve many brain areas, not all affected equally. Studies of language development show that critical periods apply more to learning accent formation than to learning grammar. In music, a study shows that perfect pitch must be learned early; other skills, such as music theory, it appears, need not be."
"Immersion fosters learning after the critical period, not only because it enforces more practice time. Adults have more difficulty learning than children in part because they have built up so many language habits that they have to overcome. This too is a product of brain plasticity: The circuits we use the most get stronger and 'outcompete' others. Immersion prevents us from reinforcing those habits."

Everything You Thought You Knew About Learning Is Wrong | GeekDad | Wired.com
From an "interview Robert Bjork, the director of the UCLA Learning and Forgetting Lab, a distinguished professor of psychology, and a massively renowned expert on packing things in your brain in a way that keeps them from leaking out."
1. Interleaving - focus on practicing different mini-skills, rather than trying to master one skill before moving on the next.
2. Vary your study location.
3. Spaced practice. Consider "taking notes just after class, rather than during — forcing yourself to recall a lecture’s information is more effective than simply copying it from a blackboard. You have to work for it. The more you work, the more you learn, and the more you learn, the more awesome you can become."
4. Forget about forgetting.

Do you know how to improve leaders? Where’s the evidence? | GoodPractice
About a presentation by David Rock, the author of the book "Your Brain at Work."(1) Only 10% of employees do their best thinking in the work place. – What does this say about the way we design work?
(2) The more we need people to remember learning in the long term, the more we need to space the training out. – What does this mean for learning design?
(3) Our brains decide 5 times a second whether to engage or not. – What does an awareness of this do to help a leader or learning design?
(4) 40% of feedback interventions make things worse. Forced rankings: the noise and threat caused far outweigh the benefits. – Effective performance management and despite all the training and work to improve this only 60% is effective? Do forced ranking do more damage than good? (5) It is important to create work spaces with no distraction for creative and important work. – What does this mean for office design?

The Brain The Trouble With Teens
"Fast driving, drugs, and unsafe sex: The risk-loving behavior of adolescents may result from a neurological gap in the developing brain. ..."The trouble with teens, [Neuroscientist B. J.] Casey suspects, is that they fall into a neurological gap. The rush of hormones at puberty helps drive the reward-system network toward maturity, but those hormones do nothing to speed up the cognitive control network. Instead, cognitive control slowly matures through childhood, adolescence, and into early adulthood. Until it catches up, teenagers are stuck with strong responses to rewards without much of a compensating response to the associated risks."

The Neuroscience of Joyful Education
"A common theme in brain research is that superior cognitive input to the executive function networks is more likely when stress is low and learning experiences are relevant to students. Lessons that are stimulating and challenging are more likely to pass through the reticular activating system (a filter in the lower brain that focuses attention on novel changes perceived in the environment). Classroom experiences that are free of intimidation may help information pass through the amygdala's affective filter. In addition, when classroom activities are pleasurable, the brain releases dopamine, a neurotransmitter that stimulates the memory centers and promotes the release of acetylcholinem, which increases focused attention."

Neuroscientists try to unlock the origins of creativity
"Dr. Vartanian is on a quest some neuroscientists have come to see as quixotic: to map and understand the brain circuitry involved in creative thinking. Fifteen years of brain imaging studies have left researchers unable to define the regions and networks that are involved, although they have debunked the myth that creativity is seated in the right side of the brain and begun to explore the intriguing possibility that it is related to the ability to silence our inner critic. ... The research is challenging. It is hard to get people to be truly creative in a brain scanner ... He found that a part of the brain that plays a role in self-restraint and evaluation – the inner critic – powered down when the musicians were improvising, while an area associated with self-expression ramped up."

Searching the Brain for the Spark of Creative Problem-Solving - NYTimes.com
Scientists have found indications that your ability to jump to intuitive answers — what they term the “Aha!” moment — may be affected by your mood. "... people were more likely to solve word puzzles with sudden insight when they were amused ... doing a crossword or a Sudoku puzzle typically shifts the brain into an open, playful state that is itself a pleasing escape". Humor can move the brain into a similar state. "Dr. Beeman and Dr. Subramaniam had college students solve word-association puzzles after watching a short video of a stand-up routine by Robin Williams. The students solved more of the puzzles over all, and significantly more by sudden insight, compared with when they’d seen a scary or boring video beforehand." Keywords: openness, humor, jokes

Why the Mind Sees the Future in the Past Tense
Remembering the future. "There is a growing conviction within neuroscience that one of the human mind's chief preoccupations is prediction. Jeff Hawkins, the founder of Palm Computing who is now afull-time neuroscientist, argued in his 2004 book "On Intelligence" that the mind does this by detecting a familiar pattern in its input, then anticipating from past experience what usually follows. The more unexpected something is, the more conscious we are of it. ... Daniel Schacter of Harvard University has made the remarkable discovery that the same parts of the mind hold both our episodic memories and our imagined futures. That is to say, if asked to imagine some specific future event, people activate the very same regions of the brain as they do when asked to recall some particular past event."

The brain isn’t going to take it lying down « Mind Hacks
"A field of study called ‘embodied cognition‘ has found lots
of curious interactions between how the mind and brain manage our
responses depending on the possibilities for action. For example, we
perceive distances as shorter when we have a tool in our hand and
intend to use it, and wearing a heavy backpack causes hills to appear
steeper." How we respond to situations may depend on our position. When
dealing with anger "when the participants were angry and sitting up,
the left frontal lobe was much more active than the right – but when
angry and lying down, there was no difference."

How brain learns to act automatically
"People who excel at a particular activity don’t necessarily
excel at teaching or explaining that activity to others. ... That’s
because motor skills are learned in one part of the brain and classroom
instruction and information read in a book are acquired in another area
... These areas without explicit reasoning are grasped in a lower part
of the brain, the basal ganglia. “It is similar to the fact that you
can’t explain what your fingers are doing when you are playing the
piano.” However, once a behavior becomes automatic, it becomes
cortical. “Automatic behaviors are stored in similar ways, in the
frontal cortex, regardless which system of the brain learned it first,”

Researchers from Kent State Say Practice Tests Improve Memory
“Taking practice tests – particularly ones that involve
attempting to recall something from memory – can drastically increase
the likelihood that you’ll be able to remember that information again
later,” Dr. Katherine Rawson said. “Given that hundreds of experiments
have been conducted to establish the effects of testing on learning,
it’s surprising that we know very little about why testing improves
memory." In the article titled “Why Testing Improves Memory: Mediator
Effectiveness Hypothesis,” Rawson and Pyc reported an experiment
indicating that at least one reason why testing is good for memory is
that testing supports the use of more effective encoding strategies."

manually manipulating and drawing out two-dimensional things we see all
the time,' says Karin Harman James" at Indiana University who led the

No Gain from Brain Training : Nature News
The largest trial to date of 'brain-training' computer games
found there were no transfer effects to general cognition. In the BBC
study 11,430 volunteers (ages 18-60) completed a series of online tasks
for a minimum of 10 minutes a day, 3 times a week, for 6 weeks. In one
group, the tasks focused on reasoning, planning and problem-solving. A
second group focused on functions targeted by commercial brain-training
programs: short-term memory, attention, visuospatial abilities and
math. A third group used the Internet to find answers to obscure
questions. “There were absolutely no transfer effects from the training
tasks to more general tests of cognition”, says Adrian Owen, a
neuroscientist at the Medical Research Council (MRC) Cognition and
Brian Sciences Unit in Cambridge, UK, who led the study. However, Peter
Snyder, a neurologist who studies ageing at Brown University said “I
really worry about this study—I think it's flawed”. Author: Alla
