Science is showing how the brain's development affects free will | Philadelphia Inquirer | 01/08/2012
A baseball player, for example, "sees the ball and hits the ball" without waiting to think about it. The batter has practiced recognizing the pitch and timing the swing until lower nerve centers govern the process. Similarly, a skilled pianist is able to perform complex compositions on the keys while carrying on a conversation or planning a dinner. The individual brain forms many such connections through thousands of hours of practice; other modules have developed in the brain of the species over millions of years of evolution. Therefore, we jump when something is slithering in the nearby grass, even those of us who have never seen a snake; moreover, we share this innate response with other primates on the same basis.
I’ve just written a piece for the Discover Magazine blog The Crux about a new study that used anaesthetics to “put people under” and test the limits of their conscious mind even after they’d stopped responding to the outside world. Doing psychology experiments on people undergoing anaesthesia is not a new idea but it has always been done on people who volunteered due to undergoing genuine surgery. But this was the first study to put volunteers under anaesthesia solely as part of an experiment. In this case, the experiment tested whether people had conscious experiences despite being unable to respond to outside stimuli – the medical definition of being unconscious. It turns out the conscious mind keeps working way past the point where people are medically defined as unconscious. In addition to the standard surgical way of checking unconsciousness, participants were also regularly asked to open their eyes to check when they stopped and started responding.

Molecular and Cellular Neuroscience : A transcriptomic analysis of type I-III neurons in the bed nucleus of the stria terminalis
The activity of neurons in the anterolateral cell group of the bed nucleus of the stria terminalis (BNST ALG ) plays a critical role in anxiety- and stress-related behaviors. Histochemical studies have suggested that multiple distinct neuronal phenotypes exist in the BNST ALG . Consistent with this observation, the physiological properties of BNST ALG neurons are also heterogeneous, and three distinct cell types can be defined (Types I–III) based primarily on their expression of four key membrane currents, namely I h , I A , I T , and I K(IR) . Significantly, all four channels are multimeric proteins and can comprise of more than one pore-forming α subunit. Hence, differential expression of α subunits may further diversify the neuronal population. However, nothing is known about the relative expression of these ion channel α subunits in BNST ALG neurons.
It’s a moral and ethical problem that has been studied before: you see a train heading towards five hikers and you have the power to save them. Just pull a switch to make the train swerve out of the way on another track. BUT you’ll kill another hiker who won’t see the train coming at all.

Want to be happy? Don't live in the UK | Money
Miserable weather, not enough holidays, and lower life expectancy ... why live in the UK? Photograph: Gerry Penny/EPA The UK and Ireland have been named as the worst places to live in Europe for quality of life, according to research published today. The UK has the 4th highest age – 63.1 – at which people choose or can afford to take retirement, and one of the lowest holiday entitlements. Net household income in the UK is just £2,314 above the European average, compared with £10,000 above average last year, falling behind Ireland, the Netherlands and Denmark.
The Blog : The Mystery of Consciousness
(Photo by AlicePopkorn ) You are not aware of the electrochemical events occurring at each of the trillion synapses in your brain at this moment. But you are aware, however dimly, of sights, sounds, sensations, thoughts, and moods. At the level of your experience, you are not a body of cells, organelles, and atoms; you are consciousness and its ever-changing contents, passing through various stages of wakefulness and sleep, and from cradle to grave. The term “consciousness” is notoriously difficult to define. Consequently, many a debate about its character has been waged without the participants’ finding even a common topic as common ground.
Powerful Facts About Visual Communication | The Mindjet Blog
Did you know that visuals are processed 60,000 times faster than text? Or how about the fact that they are processed simultaneously? I wanted to share some interesting facts about visuals with you today from an article by Mike Parkinson of billiondollargraphics.com .Elvis in potato chip neuroscience
A new study just published in Cerebral Cortex on the neuroscience on how we see meaningful information in unpatterned visual scenes, seems a little fixated on Elvis. The study concludes: Future studies of the neural processing relevant to pareidolia and to meaning more generally may provide novel insights into how the organization of conceptual processing differs across individuals (see also Pizzagalli et al. 2001), thereby addressing the question of what neurocognitive architecture is necessary to see a potato chip not just as a tasty snack but as the embodiment of Elvis.L'homéopathie, la phytothérapie, la thérapie neurale, ainsi que les médecines anthroposophique et chinoise traditionnelle seront à nouveau remboursées par l'assurance de base dès janvier 2012.

Nov. 10, 2011 — The Coma Science Group (CRCyclotron, University of Liège /Liège University Hospital), led by Dr Steven Laureys, has developed, along with its partners in London, Ontario, (Canada) and Cambridge (England), a portable test which will permit a simpler and less expensive diagnosis of 'vegetative' patients who still have consciousness, despite the fact that they do not have the means to express it. The researchers' conclusions are published this week in The Lancet . The desire to develop this simple test of consciousness, at the patient's bedside, follows on from previous research carried out by the Coma Science Group.
