POPSHumor Shown To Be Fundamental To Our Success As A Species The Pattern Recognition Theory of Humour by Alastair Clarke answers the centuries old question of what is humour. Clarke explains how and why we find things funny and identifies the reason humour is common to all human societies, its fundamental role in the evolution of homo sapiens and its continuing importance in the cognitive development of infants.

POPSThe search for the roots of psychopathy Research is being done to study the brains of psychopaths in prison using a portable functional magnetic-resonance-imaging scanner, looking for a defect , with the goal of discovering a treatment. "Although the number of psychopaths who are not in prisons is thought to exceed the number who are—if the one-per-cent figure is correct, there are more than a million psychopaths at large in the United States alone—they are much harder to identify in the outside world. Some are “successful psychopaths,” holding down good jobs in many types of industries. It is generally only if they commit a crime and enter the criminal-justice system that they become available for research." I've known at least two psychopaths personally, neither incarcerated. They are scary people.

POPSDo we get wiser with age? "Is age a prerequisite for wisdom, though? We all know a few elderly people who lack wisdom, while we may know few young people that have wisdom in spades. People certainly aren't always at peak brainpower in old age; after all, when wrinkles begin appearing on the face, it usually means that wrinkles have started disappearing on the brain. The brain shrinks slightly with age, and aging leads to a normal decline in cognitive function that may eventually bloom into dementias such as Alzheimer's disease".

POPSUnderstanding the nervous system by walking in a neuron's shoes “The problem is that the relationship between inputs and outputs is very complicated, even for a single neuron,” Fiorillo told PhysOrg.com. “By contrast, I have tried to figure out what a neuron knows about the world. This is possible because we already know a great deal about the biophysical properties of neurons. I think that if we can figure out what information a neuron has, then we will be able to make better sense of its inputs and outputs. I think that this approach to information will prove to be very useful, regardless of the success of the rest of the theory.” Interesting to read.

POPSOlfactory Neurons Use Sophisticated Fuzzy Coding They concluded that the peripheral code combines precise coding with fuzzy, stochastic responses in which neurons show apparent unpredictability in their responses to a given odour. They now believe that fuzzy coding occurs in other organisms, is translated into differing degrees of activation in the brain, and forms a key component of odour recognition in the first stages of olfactory processing. Dr McCrohan explains: “The nose gives us insight into the brain - it’s not a computer, it’s not precise, it’s fuzzy. This may be a consequence of way the receptors are built and must be used in some way as part of the process by which the brain perceives an almost infinite variety of odours.

POPSScientists adapt economics theory to trace brain's information flow Scientists believed the frontoparietal cortex was influencing the visual cortex, but the brain scanning approach they were using, functional magnetic resonance imaging (fMRI), can only complete scans about once every two seconds, which was much too slow to catch that influence in action. When researchers applied Granger causality, though, they were able to show conclusively that as volunteers waited for the stimulus to appear, the frontoparietal cortex was influencing the visual cortex, not the reverse.

POPSCalming your thoughts through mindfulness "We want to move into a place where the outside world will do whatever it's going to do without us going through the roller coaster of emotions," Rogers says. "We want to maintain this more alive, vigilant, present way of being that is somewhat independent of how things are going."

POPSThinking cap unlocks hidden genius Australian scientist Allan Snyder says that "switching off" parts of the brain can unlock the hidden genius in all of us. This is achieved by stimulating parts of the brain with tiny magnetic pulses, induced by a hairnet-like cap.

POPSBeauty and the Brain Future work may elucidate the long-term effects of one's surroundings on brain function and the relationship between aesthetically pleasing spaces and their functionality. What one considers beautiful is, of course, influenced by culture, learning, and experience, and not everything we find beautiful will ultimately be traceable to the structure and function of our brain. The larger question "What is beauty?" still poses a major challenge, but answering it no longer seems so impossible.

POPSThe New Science of Fear: Can It Predict Bravery at 13,500 Feet?
"Mujica-Parodi says:"You're kind of like a rubber band, in that when you go up, you come back down right away. You're conserving your sympathetic dominance for when it's actually needed." These results, Mujica-Parodi says, mirror those of my fMRI session. It's not that I stayed cool when I was plummeting toward earth—"You were in actual danger," she says, so "a strong excitatory response was appropriate"—but that when I wasn't falling I suppressed the fear response and conserved my energy. The upshot: I might do well at keeping calm in the face of lethal danger, as most firemen and policemen do. More important, my results seem to reinforce Mujica-Parodi's theory, which could mean that in the future recruiters for the military and law enforcement will have a way to screen applicants for the most suitable training and job assignments. Our conversation turns back to the sky dive. "Would you go again?" Mujica-Parodi asks. "I think so," I tell her. But not right now. Maybe in a fe

POPSThe Evolving AI Ecosystem He takes his theory further, all the way in to the tubes of the internet. In collaboration with Professor Tim Berners-Lee – the co-inventor of the World Wide Web – the pair have been investigating the next generation Web. “What is emerging now is a digital ecosystem,’ says Professor Shadbolt, ‘involving lots of simple systems which connect millions of complex ones – humans!” And there begins to be a certain amount of logic and a lessening of the fear I feel for the day when I am some robots whipping boy. We see such developments already in websites such as Facebook and Flickr, and programs such as Google Earth and World of Warcraft. We are being linked together, ever so slowly by a collective consciousness.

POPSOLDS: Preparing for a neuroscience revolution Our challenge is that we don't pay enough attention to such game-changing discoveries as they are happening. And when we don't pay attention, then the societal conversations that need to happen to reach consensus on policy also don't happen - at least in a proactive fashion. We end up reacting instead. In the case of the uncovering the secrets of the human mind, such proactive consideration would be better off earlier than later. The writer is James Olds is the director of the Krasnow Institute for Advanced Study at George Mason University. This is an important read.

POPSBoredom a sickness or a creative tool? "In experiments in the 1970s, psychiatrists showed that participants completing word-association tasks quickly tired of the job once obvious answers were given; granted more time, they began trying much more creative solutions" "In a recent paper in The Cambridge Journal of Education, Teresa Belton and Esther Priyadharshini of East Anglia University in England reviewed decades of research and theory on boredom, and concluded that it’s time that boredom “be recognized as a legitimate human emotion that can be central to learning and creativity.”

POPSEmotion and Confirmation Bias Where there is no skepticism and clear-thinking, we have the emotional attachment of those worshiping theory and living in a hypothetical world. Theirs is a devotion to an idea, which is actually a faith. Hope and change, anyone? Climate Change?

POPSWill Our Future Brains Be Smaller? Why does the brain need these two decision-making areas? What benefit does the new cortex bring? After all, extra brain means extra weight and energy required to carry it around. Furthermore, is the older sub-cortical system now largely redundant? If so, could we expect it to atrophy in future humans so our brains become smaller? The results of their modelling showed that when the threat level is high, such as the risk of being attacked by a dangerous animal, it is very useful to have the fast-acting, if inaccurate, system. But when dealing with situations which don't occur very often, or complex scenarios with many conflicting cues such as social situations, the cortical system is of more use than the sub-cortical system.

POPSThis is my "Stalker Theory of Romantic Movies"! I have thought for years that a lot of the mildly inappropriate stalker-y behavior that some guys exhibit can be blamed on stalking disguised as romance in movies. Singing in the Rain? Gene Kelly stalks Debbie Reynolds. You've Got Mail? Please, don't get me started. Guys and Dolls? Marlon Brando MUST know better than Jean Simmons what she wants/needs! Cinderella? Yeah, that's normal behavior - if she didn't give you her name, go door to door until you find her. /rant.
