Criterios microbiologicos. "Creativity is not a team sport": Interview Vincent Walsh, Prof Neuroscience UCL - Improvides. Today’s interview makes me feel quite honoured. It’s with Prof Vincent Walsh of UCL, one of the world’s preeminent cognitive neuroscientists with a strong interest in the study of creativity. Here we talk about how your brain generates ideas, how you’re aware of less than 1% of your brain’s activity, and the science which shows that creativity is not a team sport.

In the video above (shortened interview), we cover a vast range of topics related to the neuroscience of creativity. I have also included the Top 6 most interesting points from the extended interview here (some of which are in addition to what’s in the video). I know that some of you may disagree with some of these points (in some cases strongly disagree) and I encourage you to share your thoughts in the comments. I first came across Professor Walsh’s work about a year ago when I was uncovering what actually makes people have ideas. 1. 2. 3.

Anthropologists at Johannes Gutenberg University Mainz and geneticists at University College London, working in collaboration with archaeologists from Berlin and Kiev, have analyzed ancient DNA from skeletons and found that selection has had a significant effect on the human genome even in the past 5,000 years, resulting in sustained changes to the appearance of people. There has been much research into the factors that have influenced the human genome since the end of the last Ice Age. Anthropologists at Johannes Gutenberg University Mainz (JGU) and geneticists at University College London (UCL), working in collaboration with archaeologists from Berlin and Kiev, have analyzed ancient DNA from skeletons and found that selection has had a significant effect on the human genome even in the past 5,000 years, resulting in sustained changes to the appearance of people.

"In Europe we find a particularly wide range of genetic variation in terms of pigmentation," adds co-author Dr. The Brain: 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 so-called transcranial-magnetic-stimulation (TMS) test allows scientists to infer the function of neurons just beneath the coil. In the piano players, the TMS mapped how much of the motor cortex controlled the finger movements needed for the piano exercise. Does the internet promote fairness of income distribution? (w/ Video) (Phys.org) —The question of how an economic system should be structured in order to best promote fairness and equality is one of the most debated subjects of all time. By approaching the complexities of this question from the field of network science, researchers from MIT and other institutions have found that the average degree to which individuals in a society are connected to each other can crucially affect the fairness of income distribution.

The researchers, J. Borondo, et al., have published a paper on their research in a recent issue of Scientific Reports. In their study, the researchers constructed a model in which individuals can earn income in two ways: by producing content or by distributing the content produced by others. A system in which more income is earned by production than by distribution is labeled as meritocratic, while one in which more income is earned by distribution is called topocratic. Anti-protest law changes Twitter users' behavior, but not network structure, physicists show. (Phys.org) —With the rise of social media, it is possible to organize public demonstrations on larger scales and in less time than ever before. In response, some governments are trying to decide how to regulate and impede the organization of these demonstrations, in order to maintain safety, order, or for other reasons. But very little is known about exactly how repressive legislation affects social media networks and their users.

New research now suggests that social networks may be surprisingly resistant to such legislation. In a new paper published in EPL, Marianne Marcoux and David Lusseau at the University of Aberdeen in Aberdeen, UK, have analyzed millions of tweets from Twitter users in Quebec, Canada, who were protesting an increase in college tuition in 2012. On May 18, after 14 weeks of the strike, the Quebec government passed special emergency legislation called Bill 78 in an attempt to block the organization of the protests.

Liberalism and libertarianism share a root word as well as a common history, but today liberals and libertarians are often far apart on economic and political issues, especially in the US. I’ll try to get to the bottom of the current divisions, giving due respect to the self-serving talking points repeated by each side, which is to say no respect at all to what partisan liberals and libertarians pretend to believe.

I’m more interested in the principles that can be deduced from what such partisans say or that are indicated by their political actions. The principles I detect are rather shocking. As I’ve spelled out in Liberalism and elsewhere, modern liberals must be distinguished from postmodern ones, and postmodern liberals are disgraced, nihilistic servants of stealth oligarchies; moreover, as I’ve explained in Conservatism, libertarians craft noble lies on behalf of those same oligarchies. The Ironic Undoing of Liberalism Libertarianism as Disguised Social Darwinism. Rants Within the Undead God. Dateline: NEW YORK—A team of doctors from the Columbia Medical Center succeeded in generating new human hair growth, which promises a cure for baldness.

“We’re within sight of the cure,” said one of the lead scientists. “Of course, you have to be a hawk to see it; certainly, no one within our lifetime or that of our children’s children will see the cure, since the clinical trial period to test the results from every conceivable angle will take approximately five centuries.” Bald men responded to the news by rioting in droves, breaking into scientific labs and demanding that “the beady-eyed scientists produce the cure immediately already,” because bald men “are sick of being pariahs,” as one of them put it in the midst of a hostage situation.

Holding a gun to a medical researcher’s head, which happened also to be bald, the irate bald man exclaimed to no one in particular, “Think of what I could do with a full head of hair! Think of how much time I’ve lost being a bald nobody.” Rants Within the Undead God. Psychiatry, Anxiety Disorders, and Existential Angst. Is there a relationship between clinical anxiety and existential angst?

If so, what existential role do psychiatrists play in treating anxiety disorders? I’ll address these and related questions in what follows. Anxiety Disorders “Anxiety,” meaning a displeasing feeling of fear and concern that causes worry, uneasiness, or dread as well as physical symptoms like fatigue and concentration problems is a blanket term in psychiatry covering a number of mental disorders, including phobias, panic disorder, obsessive-compulsive disorder, posttraumatic stress disorder, and social anxiety disorder.

Let’s turn to the more specific anxiety disorder, OCD, which Wikipedia says is “characterized by intrusive thoughts that produce uneasiness, apprehension, fear, or worry; by repetitive behaviors aimed at reducing the associated anxiety; or by a combination of such obsessions and compulsions.” Clinical Anxiety and Existential Angst Some Red Herrings Some red herrings need to be tossed aside here.

Transient pleasure, prolonged pain By Liam Farrell The vein stands up proudly. Beside the syringe lies the pack of Cyclimorph, empty now, and ominous, a small harbinger of doom, the rumble of distant thunder at a summer picnic. The discarded packaging of the needles, ampoules and syringe lie in a tidy little pile.

Introduction Memory systems select from the thousands of stimuli in the environment those to encode permanently. Scientists have tried to understand long-term memory (LTM) processes through a variety of approaches including using repeated, spaced stimuli (Ebbinghaus, 1913; Pavlov, 2010).

Pavlov and his associates focused on memory encoding of demonstrably new associations (a link between the sound of a bell and food), and Ebbinghaus on memory retrieval, testing himself with word-like sequences of nonsense syllables. For almost a century after these first studies there remained two intractable issues: first, what was the physical basis of LTM encoding, and second, how could it be triggered most effectively? (Fields, 2005, 2011). Recently a robust model of LTM formation has emerged through studies of late Long-Term Potentiation (LTP) and LTM in many different contexts and species (Morris, 2003).

Studies of LTP/LTM encoding have time patterns that reflect the speed neurological processes.
