Scientists extract images directly from brain ::: Pink Tentacle Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. For now, the system is only able to reproduce simple black-and-white images. "These results are a breakthrough in terms of understanding brain activity," says Dr.
Transcranial magnetic stimulation Background Early attempts at stimulation of the brain using a magnetic field included those, in 1910, of Silvanus P. Thompson in London. The principle of inductive brain stimulation with eddy currents has been noted since the 20th century. The first successful TMS study was performed in 1985 by Anthony Barker and his colleagues at the Royal Hallamshire Hospital in Sheffield, England. Its earliest application demonstrated conduction of nerve impulses from the motor cortex to the spinal cord, stimulating muscle contractions in the hand. As compared to the previous method of transcranial stimulation proposed by Merton and Morton in 1980 in which direct electrical current was applied to the scalp, the use of electromagnets greatly reduced the discomfort of the procedure, and allowed mapping of the cerebral cortex and its connections. Theory From the Biot–Savart law it has been shown that a current through a wire generates a magnetic field around that wire. Risks
Eidetic memory -photographic memory Overview The ability to recall images in great detail for several minutes is found in early childhood (between 2% and 10% of that age group) and is unconnected with the person's intelligence level. Like other memories, they are often subject to unintended alterations. The ability usually begins to fade after the age of six years, perhaps as growing vocal skills alter the memory process. A few adults have had phenomenal memories (not necessarily of images), but their abilities are also unconnected with their intelligence levels and tend to be highly specialized. Persons identified as having a related condition known as Highly Superior Autobiographical Memory (HSAM) are able to remember very intricate details of their own personal life, but this ability seems not to extend to other, non-autobiographical information.

street art “Lo bueno de la calle es que es libre. Las reglas las pones tú. El público suele ser receptivo. Nos interesa esa respuesta inmediata”, asegura 3ttman el grafittero francés radicado en Madrid. Una afirmación que se podrá ver y contrastar esta semana a través del stand de EL PAÍS en Arco, donde participa él y otros cinco artistas, así como en el debate que ha organizado este periódico sobre Arte urbano. Buen momento para apreciar una manifestación creativa callejera que ha entrado en los museos y servido de expresión del sentir de la sociedad. Días para lanzar preguntas y resolver dudas en torno al mundo del arte y sus fronteras. Un solo acto o gesto con el cual intervienen la ciudad con múltiples resultados, como lo resume la experiencia de Nuria Mora: “Al irme a vivir al centro de Madrid me di cuenta de cómo se estaba degradando.
Neuroscientists reveal magicians' secrets - Technology & science - Science - LiveScience - NBCNews.com NEW YORK — There is a place for magic in science. Five years ago, on a trip to Las Vegas, neuroscientists Stephen Macknik and Susana Martinez-Conde realized that a partnership was in order with a profession that has an older and more intuitive understanding of how the human brain works. Magicians, it seems, have an advantage over neuroscientists. "Scientists have only studied cognitive illusions for a few decades. She and Macknik, her husband, use illusions as a tool to study how the brain works. After their epiphany in Las Vegas, where they were preparing for a conference on consciousness, the duo, who both direct laboratories at the Barrow Neurological Institute in Arizona, teamed up with magicians to learn just how they harness the foibles of our brains. The psychological concepts behind illusions are generally better understood, but they treat the brain as something of a black box, without the insight into brain activity or anatomy that neuroscience can offer, they write.
Technology Review: Brain Coprocessors Ed Boyden, an Assistant Professor, Biological Engineering, and Brain and Cognitive Sciences at the MIT Media Lab, will give a presentation on using light to study and treat brain disorders at 3.30pm on Wednesday at EmTech 2010. Watch a live feed of the session here. The last few decades have seen a surge of invention of technologies that enable the observation or perturbation of information in the brain. Functional MRI, which measures blood flow changes associated with brain activity, is being explored for purposes as diverse as lie detection, prediction of human decision making, and assessment of language recovery after stroke. This toolbox has grown to the point where the strategic utilization of multiple neurotechnologies in conjunction with one another, as a system, may yield fundamental new capabilities, both scientific and clinical, beyond what they can offer alone.
Learn more quickly by transcranial magnetic brain stimulation, study in rats suggests What sounds like science fiction is actually possible: thanks to magnetic stimulation, the activity of certain brain nerve cells can be deliberately influenced. What happens in the brain in this context has been unclear up to now. Medical experts from Bochum under the leadership of Prof. Dr. The researchers have published their studies in the Journal of Neuroscience and in the European Journal of Neuroscience. Magnetic pulses stimulate the brain Transcranial magnetic stimulation (TMS) is a relatively new method of pain-free stimulation of cerebral nerve cells. Repeated stimuli change cerebral activity Since the mid-1990's, repetitive TMS has been used to make purposeful changes to the activability of nerve cells in the human cortex: "In general, the activity of the cells drops as a result of a low-frequency stimulation, i.e. with one magnetic pulse per second. Contact points between cells are strengthened or weakened Inhibitory cortical cells react particularly sensitive to stimulation
life as a pilgrimage john bunyan and the modern life course Better, though difficult, the right way to go, Than wrong, though easy, where the end is Woe. (The Pilgrim’s Progress, 39) Protestantism is not only a religious conviction but also a culture. However, Calvinism did not only puts its mark on our economical and political culture, but also on psychology and morality, not only on the pub-lic domain but also on the soul of the citizen. In his by now classical Modernity and Self-Identity, Anthony Giddens has depicted the life course of this modern self. 1. 2. 3. 4. In this article I want to present an experiment in moral archeology. In this article I will be looking for ‘elective affinities’ (Weber, German edition, 77: ‘Wahlverwantschaften’; a concept borrowed from Goethe; the translation, p. 91 gives the flat ‘certain correlations’) between the Calvinist idea of the Christian’s pilgrimage on earth and the dominant liberal myth of the biography of choice. The path of life is slippery on both sides. 1. 2.
Study Reveals How Magic Works Scientists are figuring out how magicians fool our brains in research that also helps uncover how our mind actually works. A great deal of what scientists now understand about how the human visual system works stems from research into our susceptibility to optical illusions. "It made sense to look at magicians to advance knowledge of human cognition, since magicians have been working on figuring out how certain principles of psychology work for hundreds of years," said researcher Gustav Kuhn at the University of Durham in England, a cognitive psychologist who has also performed magic the past couple decades. "Magicians really have this ability to distort your perceptions, to get people to perceive things that never happened, just like a visual illusion," he added. The researchers looked into a magic trick called the "vanishing ball," in which a ball apparently disappears in midair. It's done by faking a throw while keeping the ball secretly palmed in the magician's hand.
Neuromarketing Neuromarketing is a new field of marketing research that studies consumers' sensorimotor, cognitive, and affective response to marketing stimuli. Researchers use technologies such as functional magnetic resonance imaging (fMRI) to measure changes in activity in parts of the brain, electroencephalography (EEG) and Steady state topography (SST) to measure activity in specific regional spectra of the brain response, and/or sensors to measure changes in one's physiological state, also known as biometrics, including (heart rate and respiratory rate, galvanic skin response) to learn why consumers make the decisions they do, and what part of the brain is telling them to do it. Neuromarketing research raised interest for both academic and business side. In fact, certain companies, particularly those with large-scale goals, have invested in their own laboratories, science personnel and / or partnerships with academia.  The word "neuromarketing" was coined by Ale Smidts in 2002. Coke vs.
