POPSBrainWorks With the help of five kids, host Eric Chudler takes viewers on a journey inside of the brain. The show begins in the studio with an introduction to the nervous system. The kids then visit laboratories where they learn about automatic functions of the brain and how the electrical activity of the brain is recorded. Back in the studio, the kids see a real human brain and build their own model nerve cells and brains.

POPSInternet use could improve brain function and speed up decision-making Previous studies have warned that too much computer use could be responsible for increasing levels of Attention Deficit Hyperactivity Disorder (ADHD). Dr Gary Small, director of the memory and ageing research centre at the University of California, Los Angeles, said: "Young people are growing up immersed in this technology and their brains are more malleable, more plastic and changing than with older brains," he said.

POPSInternet 'speeds up decision making and brain function' "The next generation, as (Charles) Darwin suggests, will adapt to this environment. Those who become really good at technology will have a survival advantage - they will have a higher level of economic success and their progeny will be better off." The brains of 24 volunteers between the ages of 55 and 76 were scanned for the study.

POPSAttention and Emotional Self Regulation 1) Alerting: helps us maintain an Alert State. 2) Orienting: focuses our senses on the information we want. For example, you are now listening to my voice. 3) Executive Attention: regulates a variety of networks, such as emotional responses and sensory information. This is critical for most other skills, and clearly correlated with academic performance. It is distributed in frontal lobes and the cingulate gyrus. The development of executive attention can be easily observed both by questionnaire and cognitive tasks after about age 3–4, when parents can identify the ability of their children to regulate their emotions and control their behavior in accord with social demands. Very interesting read.

POPSBrain and Creativity Institute The mission of the Brain and Creativity Institute is to gather new knowledge about the human emotions, decision-making, memory, and communication, from a neurological perspective, and to apply this knowledge to the solution of problems in the biomedical and sociocultural arenas.

POPSPioneering Research in Neuromorphic Electronics that Function Like the Biological Brain The HRL team's ultimate goal is to build a low-power, compact electronic chip combining a novel analog circuit design and a neuroscience-inspired architecture that can address a wide range of cognitive abilities--perception, planning, decision making, and motor control. In the initial two phases of the SyNAPSE program, the team will translate the neuronal and synaptic functions of the biological cortex into similar microelectronic functions.

POPSThe Secret Of Fast Complex Brain Restructuring Up to now, it had been assumed that nerve cells can only exchange information via the synapses which are special contact points. However, synapses require up to two days to become fully functional - a waste of time and energy if the contact is to be broken down again. The brain could take almost 1000 years to develop if a synapse had to mature at each cell contact. It appears that nerve cells can also obtain information about their neighbours even without a synapse. Neurobiologists Christian Lohmann and Tobias Bonhoeffer from the Max Planck Institute for Neurobiology have now explained how they do that. The secret to how the information is exchanged: local calcium signals very quickly transmit all the necessary information to the cell. A synapse only actually develops when the cell and the contact point prove to be suitable candidates for long-term contact.

POPSI think, therefore iPod " if the devices we use are artificial extensions of our minds, then they could be enhancing our cognitive powers more than they are diminishing them. Technology means I forget fewer birthdays, not more, for example." i find this debate fascinating. i for once support that which will assist me crossing borders of perception and limitations.

POPSCultural Neuroscience I do believe this attention to culture as every bit as important as brain activity, indeed inseparable from it, is crucial for the way we think about thinkinfg and how we think we think we are.

POPSJill Bolte Taylor: My stroke of insight You have to click the link to view. This was one of the most moving stories I have had the privilege of viewing. I am a a very BIG fan of TED for sometime now. It never ceases to amaze and educate in the most unusual and enlightening ways.

POPSImportant Comment made by "deadcowkid" to "Brain That Changes Itself" This is a very important comment by deadcowkid for the clip: 'Brain That Changes Itself" http://clipmarks.com/clipmark/378F24A4-D35D-43A7-9FF4-3C3BCF2C2CA5/ . I thank him for telling such an inspiring story. "He said the brain was misunderstood and capable of repairing itself. He told me to give it three good years".

POPSBrain That Changes Itself "The brain is a far more open system than we ever imagined, and nature has gone very far to help us perceive and take in the world around us. It has given us a brain that survives in a changing world by changing itself'

POPSShop or Drop? does it have physical correlates? some technicals citation from the article: "Researchers discovered that when the product first flashed on the screen it activated the nucleus accumbens, a section near the middle of the brain that has been implicated in the brain's reward center, effectively appraising the item. When the price appeared, the scientists noticed activity in the mesial prefrontal cortex, a region of the brain known for higher executive functions. Its activity seemed to vary according to the difference between what someone would pay for an item and its actual cost, as if in error adjustment. Finally, the response of the insula (a lateral section of the brain's cortex known to activate during responses to negative stimuli) depended on the purchasing decision--activity there increased when a participant nixed a purchase." what is interesting here is our human crave to understand more and more...
