POPSTwitter and the Global Brain In fact, judging by Twitter's Trending Topics, the re-tweeting process does not point to either good, or important content. Of course, it may not be right to assume that a global brain will be smarter, and real significance will be lost in the tsunami of celebrity drivel.

In fact, behind your question is the fundamental problem of the degree to which behaviour is innate and to which it is acquired – an essential question that philosophers and scientists have been debating for centuries. This remains an ideologically-charged subject, which the media adore. Absolutely. The media often echo works that argue that cerebral specialisation differs between male and female. They say, for example, that language functions are undertaken by both hemispheres only in women’s brains. What do you say? The theories on the hemispheric differences between the sexes in language appeared over thirty years ago. They have not been confirmed by recent brain imaging studies which allow us to see the living brain at work. These theories are often based on observations carried out on very small samples – often a dozen people. People continue to quote these studies whereas contemporary scientific reality is very different. Meta-analyses, which draw conclusions from all the exp

POPSFixing My Gaze
"It is hard to imagine the dramatic nature of the sudden epiphany that stereoblind people have if they gain stereopsis, as when Barry saw the steering wheel floating before her. Stereoblind people perceive the world in two dimensions, as a flat display; they judge distance and depth by such cues as size, shading, and the partial obscuring of one object by another. They have to develop these techniques in childhood because they suppress the information coming from one of their eyes, since the data from both eyes fail to match. Nothing in the experience of the stereoblind can prepare them for what stereoscopic vision is like. If they get it, the experience can be overwhelming; it can even cause vertigo, as happened to Barry, and sensations of travel-sickness." "It is a pleasant and optimistic thought indeed, that at any point in life we might, if determined enough, be able to fix things, improve, mend, and grow in positive ways: even to see more clearly, and not just with our eyes."

POPSA game for life "The challenge is to learn enough about the brain changes induced by different technologies and types of games in order to be able to guide them, enhancing functions that result in a functional and behavioral advantage for each individual. If done properly, the motivating, almost addictive, nature of these technologies, may actually prove a very valuable ally to achieve desired goals in education, medical treatment, and rehabilitation." I do agree to the point that it is up to us, humans, to pour the meaning into the availability that is technology.

POPSBrain could adapt well to cyborg enhancements Farné says the same kind of brain "plasticity" might be involved in regaining control of a transplanted hand or a prosthetic limb when the original has been lost. The brain might also readily incorporate cyborg additions – a cyborg arm or other body part – into its body schema, says Farné, "and possibly new body parts differing in shape and/or number, for example four arms." Small implants such as pacemakers are inserted in the existing body so do not need to be accepted by the body schema, adds Farné, "but a pair of wings would – that would be tough!"

POPSFirst visual evidence of memories being formed more at source: The finding provides the first visual evidence that when a new memory is formed new proteins are made locally at the synapse - the connection between nerve cells - increasing the strength of the synaptic connection and reinforcing the memory. The study published in Science, is important for understanding how memory traces are created and the ability to monitor it in real time will allow a detailed understanding of how memories are formed.

POPSBrain mechanisms for behavioral flexibility "We hypothesize that single neurons probably cannot switch outputs in a short period of time, so the brain realizes behavioral flexibility by preparing separate pathways for each task through learning, and then chooses the appropriate pathways, rather than switching outputs, in a given trial." That statement would indicate the possibility that our brains increase in plasticity and flexbility via learning

POPSAn interesting thought about Twitter per @wildcat2030 This is a very interesting idea. I wonder if as our brains are being trained to consume more information in less time, are we losing the ability to patiently listen, think, feel and learn because we're too quickly moving on to the next bit of information we need to process?

POPSWhat your mother did when she was young has an effect on your memory "This study and others are revolutionizing our understanding of how nature — starting with an individual's DNA sequence — and nurture — including the way life experience alters the way DNA is expressed — can combine, not only to regulate the health of subsequent generations, but also possibly the incidence of disease," said Anthony Hannan, PhD, an expert in environmental enrichment and its effects on neural plasticity at the Florey Neuroscience Institutes, University of Melbourne, in Australia who was unaffiliated with the current study." This research doesn't bode well for the next generation of Palestinians who are living under Israeli occupation.

POPSNew Discovery Could Rejuvenate the Brain “If we can target therapies that block this mechanism, then neurons should be able to sprout new connections, therefore stimulating the brain’s ability to repair its wiring network.” The research reveals that the loss of plasticity is due to the protein calpain actively blocking the protein cortactin, which is responsible for the sprouting of new connections. The researchers reduced calpain activity in animal models to unlock the sprouting potential of neurons and found that when calpain activity is reduced neural plasticity is enhanced.

POPSBrain Cells That Are A Key To Learning Discovered n experiments the researchers directly observed the convergent neurons where learning is suspected of taking place. These neurons responded to both a conditioned stimulus, in this case a novel saccharine solution, and an unconditioned stimulus, in the form of lithium chloride that made rats sick. Convergent activation is considered a key event for subsequent plasticity, according to Bernstein. Until now, however, there has been scant direct evidence of this activation during learning in the mammalian brain.

POPSMind, body and goal: the embodied cognition revolution "In one particularly striking study, Proffitt and his colleagues found that we perceive distances as shorter when we have a tool in our hand, but only when we intend to use it. They suggest that we perceive the environment in terms of our intentions and abilities to act within it".

POPSMusical training enhances integration of the senses This study shows that sensorimotor and auditory training induces cortical reorganization to a greater extent than does auditory training alone. It also shows that sensorimotor and auditory training cause more changes in the auditory cortex than auditory training alone. This phenomemon, called cross-modal plasticity, has been investigated only rarely. In 2003, the same group showed that professional trumput players have enhanced interactions between the auditory cortex and the regions of the somatosensory cortex devoted to the lip. The new study therefore provides another demonstration that the sensorimotor and auditory cortices are connected to each other.

POPSRichard Dawkins' jaw-dropping talk on our bizarre universe Richard Dawkins discusses the question of limits on human understanding. As a species we evolved to cope with the world within a particular range of physical dimensions. These determine our common sense view of the world. How far can the plasticity of our brains transcend this limitation?

POPSResearchers turn one form of adult mouse cell directly into another Joan Brugge, Chair of the Department of Cell Biology at Harvard Medical School, said the new study "provides exciting new insights into yet another aspect of cell plasticity that was not appreciated previously and that offers great potential therapeutically. Direct reprogramming represents a more straight-forward strategy to treat diseases involving loss of function of specific cell populations than approaches requiring an intermediate embryonic stem cell," she said.
