Temporally structured replay of awake hippocampal ... [Neuron. 2001] - PubMed result Adlo Will we hear the light? Public release date: 27-Mar-2011 [ Print | E-mail Share ] [ Close Window ] Contact: Lee Siegelleesiegel@ucomm.utah.edu 801-581-8993University of Utah SALT LAKE CITY, March 28, 2011 – University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain. "We're going to talk to the brain with optical infrared pulses instead of electrical pulses," which now are used in cochlear implants to provide deaf people with limited hearing, says Richard Rabbitt, a professor of bioengineering and senior author of the heart-cell and inner-ear-cell studies published this month in The Journal of Physiology. The studies – funded by the National Institutes of Health – also raise the possibility of developing cardiac pacemakers that use optical signals rather than electrical signals to stimulate heart cells. Shedding Infrared Light on Inner-Ear Cells and Heart Cells "Calcium does that normally," says Rabbitt. [ Print | E-mail

Alan Cook Neuroscience of magic 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. Magicians have studied them for hundreds, if not thousands, of years," Martinez-Conde told the audience during a recent presentation here at the New York Academy of Sciences. [ Video: Your Brain on Magic ] 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.

Alberto Corradi Transcranial magnetic stimulation Background[edit] Early attempts at stimulation of the brain using a magnetic field included those, in 1910, of Silvanus P. Thompson in London.[2] The principle of inductive brain stimulation with eddy currents has been noted since the 20th century. Theory[edit] From the Biot–Savart law it has been shown that a current through a wire generates a magnetic field around that wire. This electric field causes a change in the transmembrane current of the neuron, which leads to the depolarization or hyperpolarization of the neuron and the firing of an action potential.[5] Effects on the brain[edit] The exact details of how TMS functions are still being explored. Single or paired pulse TMS causes neurons in the neocortex under the site of stimulation to depolarize and discharge an action potential. Use in localisation of sensorimotor cortex[edit] Risks[edit] Other adverse effects of TMS are: Clinical uses[edit] The uses of TMS and rTMS can be divided into diagnostic and therapeutic uses.

Alberto Pagliaro 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. Klaus Funke (Department of Neurophysiology) have now shown that various stimulus patterns changed the activity of distinct neuronal cell types. In addition, certain stimulus patterns led to rats learning more easily. 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 Contact points between cells are strengthened or weakened It is unknown to a great extent how precisely the activity of nerve cells is changed by repeated stimulation.

Alessandro Barbucci Magnetic Mind Control How Does the Brain Work? PBS Airdate: September 14, 2011 NEIL DEGRASSE TYSON: Hi, I'm Neil deGrasse Tyson, your host for NOVA scienceNOW, where this season, we're asking six big questions. On this episode: How Does the Brain Work? To find out, I head to Las Vegas, where brain researchers are placing their bets on magic. MAC KING (Magician): That's a dang real fish. NEIL DEGRASSE TYSON: Some of the world's top magicians... PENN JILLETTE (Magician): Place the ball... NEIL DEGRASSE TYSON: ...are making the mysteries behind our most powerful organ disappear... I saw it go over! The illusionists reveal their secrets That motion will draw the eye ...giving us new insight into how our brain pays attention. STEPHEN MACKNIK (Barrow Neurological Institute): This would be a major contribution to science from the magicians. NEIL DEGRASSE TYSON: Also, a magnetic wand ... MO ROCCA (Correspondent): Oh! NEIL DEGRASSE TYSON: ... that can control your body,... MO ROCCA: Ooh, wow! Keep your eye on the ball, son. Maria?

Ok I may be wrong about this one but I think this was what the other link was "Strange Stuff And Funky Things" > is odd because the same pearl is in one of my other pearltrees and is unchanged . So I can't be 100% sure I have the links correct . by mirlen101 Apr 4

Ok I think I figured out what the two links were, here's the first one "Temporally Structured Replay of Awake Hippocampal " > by mirlen101 Apr 4

That is weird ! I just noticed another one with almost the same title ! Obviously the titles have been changed also . This is the first time I've seen anything like this happening . Don't see anyway of knowing what the links were before they were changed ! That really pisses me off ! Losing 2 major links ! by mirlen101 Apr 4

Do you know what this link originally was? I've gotten a few messages saying people pearled this from me, but it looks like the link has been destroyed. by rossbusby Apr 3
