Did a Copying Mistake Build Man's Brain? A copying error appears to be responsible for critical features of the human brain that distinguish us from our closest primate kin, new research finds. When tested out in mice, researchers found this "error" caused the rodents' brain cells to move into place faster and enabled more connections between brain cells. When any cell divides, it first copies its entire genome. Did a Copying Mistake Build Man's Brain?
Brain Scans Show Who You're Thinking About March 13th, 2013 | by Charles Q. Choi Scientists scanning the human brain can now tell whom a person is thinking of, the first time researchers have been able to identify what people are imagining from imaging technologies.

The Invisible Hand Illusion – Phenomena The Invisible Hand Illusion – Phenomena Hold your hand up in front of your face. It is patently obvious that the five-fingered thing in front of you is your hand, and the empty space next to it is not. But this ability to recognise your own body is more complicated than it first appears, and can be fooled through a surprisingly simple trick. Henrik Ehrsson from the Karolinska Institute is a master of such illusion. When I visited his lab in 2011, he used little more than virtual reality headsets, mannequins and batons to convince me that I had left my body, shrunk to doll-size, and gained a third arm.
Jeanna Bryner, LiveScience Managing Editor | June 13, 2012 08:26am ET Credit: Dreamstime Sitting in total silence, palms facing upward and eyes closed, mouthing the traditional "Ommmmm" sounds, would seem a practice for monks and other ascetic humans. Turns out, various types of mindful meditation (no Tibetan temple needed) can fit perfectly into the lives of a 9-to-5 business man or woman. And plenty of science suggests the benefits can be great. Here are seven enlightening benefits. 7 Reasons You Should Meditate | Mindfulness Meditation Health Benefits 7 Reasons You Should Meditate | Mindfulness Meditation Health Benefits
Nuts and Bolts the neuron A single neuron may be connected to as many as 200 000 others, via junctions called synapses. They form an extensive network throughout the body, and can transmit signals at speeds of 100 metres per second. This enables animals to process and respond to events rapidly, for example by carrying sensory information from the ears to the brain, then instructions for movement from the brain to the leg muscles Within a neuron, signals are transmitted by a change of membrane voltage – a variation in the difference in electrical charge between the inside and outside of the cell. This electrical signal moves along the neuron as an electrical pulse (the ‘action potential’). The nature of the connection between neurons was hotly debated until early-20th-century experiments by Otto Loewi and Sir Henry Dale (a founding trustee and chairman of the Wellcome Trust) showed that signals are typically transmitted across synapses by chemicals called neurotransmitters.

Sex or Attachment: Why Do We Fall in Love, Really? By Bonnie Williams
Jedidiah Becker for redOrbit.com — Your Universe Online A recent study by neuroscientists at Johns Hopkins University has torn the bottom out of a widely accepted theory about how the brain creates memories. The old paradigm held that the ability to form long-term memories depended largely on the activity of a single enzyme in the brain, a notion that now appears to be entirely incorrect. In a report of their research published in the January 2 issue of the journal Nature, the researchers described how an experiment with mice inadvertently demonstrated that the enzyme in question — known as PKM-zeta — cannot be as critical as once thought, since mice that lacked the enzyme were still able to create long-term memories.

Spurious Positive Mapping of the Brain? Many fMRI studies could be giving false-positive results according to an important new paper from Anders Eklund and colleagues: Does parametric fMRI analysis with SPM yield valid results?—An empirical study of 1484 rest datasets. The authors examined the SPM8 software package, probably the most popular tool for analyzing neuroimaging data. Their approach was beautifully simple. Spurious Positive Mapping of the Brain?
Brain scan breakthrough show researches just what you're thinking about and could lead to treatment for disorders like autism By Daily Mail Reporter PUBLISHED: 04:57 GMT, 15 March 2013 | UPDATED: 10:11 GMT, 15 March 2013 Brain scans now allow researchers to know exactly what a person is imagining. The latest breakthrough comes after scientists used brain scans to decode images directly from the brain. Researchers have been able to put together what numbers people have seen, the memory a person is recalling, and even reconstruct videos of what a person has watched.

Brain Notes

What the McLean brain bank malfunction means for autism research | Simon Baron-Cohen | Comment is free The sensitivities of organ donation mean that brain banks' tissue collections take years of patient effort to acquire. Photograph: Graeme Robertson for the Guardian This week, the freezer at the Harvard-affiliated McLean Hospital broke down, with the loss of about 150 brain samples from people who had died and who had had conditions such as autism, Parkinson's disease, Alzheimer's disease, or schizophrenia. This is bad news for at least five different communities. First, there are the families of the bereaved individuals who had to make the very difficult decision about whether to donate their loved one's brain for research, hoping that such a donation would result in scientific advance in our understanding of the causes of a condition like autism. For some relatives, such a decision will have meant wrestling with their own religious beliefs, or with their own strongly-held emotions and wishes about how their relative should be treated.
The brain's emergency response call | Science Credit: EMBL/ Francesca Peri The film clip shows shows microglial cells (labelled green) migrating towards injured neurons in the embryonic zebrafish brain. Microglia are immune cells that act as the brain's emergency workers - they constantly patrol the organ, extending and retracting their finger-like protruberances to sniff out any damage, and then migrating to an injury site to mop up dead cells and other cellular debris.
Vaughan Bell: the trouble with brain scans | Science | The Observer Neuroscientists have long been banging their heads on their desks over exaggerated reports of brain scanning studies. Media stories illustrated with coloured scans, supposedly showing how the brain works, are now a standard part of the science pages and some people find them so convincing that they are touted as ways of designing education for our children, evaluating the effectiveness of marketing campaigns and testing potential recruits. Recently, to the chagrin of French scientists, politicians called for neuro-imaging to be used in the courts to decide on the guilt of criminals, after the technology made its dubious debut in the legal systems of India, Italy and the US. This misplaced enthusiasm often stems from a misunderstanding about what brain scans tell us.
