13 Things to Avoid When Changing Habits “Habit is habit, and not to be flung out of the window by any man, but coaxed downstairs a step at a time.” - Mark Twain Post written by Leo Babauta. Follow me on Twitter. I’ve learned a lot about changing habits in the last 2 1/2 years, from quitting smoking to taking up running and GTD and vegetarianism and waking early and all that. I could go on, of course, but you get the picture. I’ve not only learned a lot about what you should do when changing habits, but through my failures, I’ve learned about what not to do.

BrainGate neural interface system reaches 1,000-day performance milestone An investigational implanted system being developed to translate brain signals toward control of assistive devices has allowed a woman with paralysis to accurately control a computer cursor at 2.7 years after implantation, providing a key demonstration that neural activity can be read out and converted into action for an unprecedented length of time. PROVIDENCE, R.I. [Brown University] — Demonstrating an important milestone for the longevity and utility of implanted brain-computer interfaces, a woman with tetraplegia using the investigational BrainGate* system continued to control a computer cursor accurately through neural activity alone more than 1,000 days after receiving the BrainGate implant, according to a team of physicians, scientists, and engineers developing and testing the technology at Brown University, the Providence VA Medical Center, and Massachusetts General Hospital (MGH). From fundamental neuroscience to clinical utility Moving forward

More Social Media Lessons from QPS in Australia: If we don’t listen, how can we hear? « idisaster 2.0 Post by: Kim Stephens I have written about the Australian Queensland Police Service and their brilliant use of social media for emergency response before. I have continued to track their feeds, and I have a few more insights into their success that I would like to share. I asked them a few questions by simply sending a tweet with their name in it: @QPSMedia. Their reputation for responsiveness is well-deserved; whoever was monitoring their twitter feed simply asked me “What do you want to know?” I didn’t want to monopolize their time, since they are currently still in response/recovery mode from the recent cyclone, but I did manage to get two questions in.

Ten Psychology Studies from 2009 Worth Knowing About - David DiSalvo - Brainspin Image by AFP/Getty Images via Daylife Several great psychology and neuroscience studies were published in 2009. Below I’ve chosen 10 that I think are among the most noteworthy, not just because they’re interesting, but useful as well. 1. If you have to choose between buying something or spending the money on a memorable experience, go with the experience. According to a study conducted at San Francisco State University, the things you own can’t make you as happy as the things you do. Neuron All neurons are electrically excitable, maintaining voltage gradients across their membranes by means of metabolically driven ion pumps, which combine with ion channels embedded in the membrane to generate intracellular-versus-extracellular concentration differences of ions such as sodium, potassium, chloride, and calcium. Changes in the cross-membrane voltage can alter the function of voltage-dependent ion channels. If the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives. Neurons do not undergo cell division. In most cases, neurons are generated by special types of stem cells.

How the Brain Stops Time One of the strangest side-effects of intense fear is time dilation, the apparent slowing-down of time. It's a common trope in movies and TV shows, like the memorable scene from The Matrix in which time slows down so dramatically that bullets fired at the hero seem to move at a walking pace. In real life, our perceptions aren't keyed up quite that dramatically, but survivors of life-and-death situations often report that things seem to take longer to happen, objects fall more slowly, and they're capable of complex thoughts in what would normally be the blink of an eye. Now a research team from Israel reports that not only does time slow down, but that it slows down more for some than for others. Anxious people, they found, experience greater time dilation in response to the same threat stimuli.

How I use OneNote for my Dissertation « ProtoScholar The question came up recently about how I am using OneNote for my dissertation note taking. Sometimes show is easier than tell. I have one OneNote notebook called Dissertation. Does the comfort of conformity ease thoughts of death? - life - 25 February 2011 AS THE light at the end of the tunnel approaches, the need to belong to a group and be near loved ones may be among your final thoughts. So say Markus Quirin and his colleagues at the University of Osnabrück in Germany. The team prompted thoughts of death in 17 young men with an average age of 23 by asking them whether they agreed or disagreed with a series of statements such as "I am afraid of dying a painful death". At the same time, the men's brain activity was monitored using a functional MRI scanner. To compare the brain activity associated with thoughts of death with that coupled to another unpleasant experience, the team also prompted thoughts of dental pain using statements like "I panic when I am sitting in the dentist's waiting room". Although the threat of dental pain is unpleasant, "it's not a threat of death", Quirin says.

Gero Miesenboeck studies the brain by controlling it. He claims that controlling and modifying is the best way to decrypt a code. Somehow he genetically re-engineered some neurons in the brain to fire on light signals. Using this method he found the 'inner critic' of fruit flies and was able to 'teach' them. ¿I'm currious about how one can encode in DNA where a given altered neuron ends up? by kaspervandenberg Nov 7
