A new functional magnetic resonance imaging (fMRI) technique may provide neurosurgeons with a non-invasive tool to help in mapping critical areas of the brain before surgery, reports a study in the April issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. http://medicalxpress.com/news/2013-04-non-invasive-localize-language-centers-brain.html Neuroscience Mon, 08 Apr 2013 12:39:51 EST news284643582 (Medical Xpress)—The superior capability of experts to rapidly solve problems depends largely on their intuition, and it has long been known that this is related to experience and training. Although many psychological models relating to the development of intuition have been proposed to explain this phenomenon, none have been validated, and the underlying neural mechanisms remain a mystery. http://medicalxpress.com/news/2013-03-game-japanese-chess-reveals-experts.html Neuroscience Fri, 22 Mar 2013 11:10:01 EST news283166195 (Medical Xpress)—The ambitious and controversial Brain Activity Map (BAM), initiative instituted by a small group of researchers last year, has been steadily gaining momentum. Earlier this week, a proof-of-principle Zebrafish BAM was demonstrated with astounding clarity by a pair of researchers at the Howard Hughes Medical Institute. http://medicalxpress.com/news/2013-03-nanotools-neuroscience-brain.html Neuroscience Fri, 22 Mar 2013 08:00:01 EST news283152606 Why do our brains make more mistakes when we act quickly? A new study demonstrates how the brain follows Ben Franklin's famous dictum, "Take time for all things: great haste makes great waste." http://medicalxpress.com/news/2012-11-insight-haste.html Neuroscience Wed, 07 Nov 2012 12:00:01 EST news271506968 When people – and monkeys – look at faces, a special part of their brain that is about the size of a blueberry "lights up." Now, the most detailed brain-mapping study of the area yet conducted has confirmed that it isn't limited to processing faces, as some experts have maintained, but instead serves as a general center of expertise for visual recognition. Neuroscientists previously established that this region, which is called the fusiform face area (FFA) and is located in the temporal lobe, is responsible for a particularly effective form of visual recognition. But there has been an ongoing debate about whether this area is hard-wired to recognize faces because of their importance to us or if it is a more general mechanism that allows us to rapidly recognize objects that we work with extensively. http://medicalxpress.com/news/2012-10-brain-auto-experts-cars-people.html Neuroscience Mon, 01 Oct 2012 15:00:10 EST news268308899 Researchers at Aalto University in Finland have developed the world's first device designed for mapping the human brain that combines whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology. MEG measures the electrical function and MRI visualizes the structure of the brain. The merging of these two technologies will produce unprecedented accuracy in locating brain electrical activity non-invasively. http://medicalxpress.com/news/2012-07-unprecedented-accuracy-brain-electrical-device.html Medical research Thu, 26 Jul 2012 10:55:28 EST news262518915 (Medical Xpress) -- Want to know why sports fans get so worked up when they think the referee has wrongly called their team's pass forward, their player offside, or their serve as a fault? http://medicalxpress.com/news/2012-02-believing.html Psychology & Psychiatry Wed, 01 Feb 2012 05:40:03 EST news247295408 People who eat baked or broiled fish on a weekly basis may be improving their brain health and reducing their risk of developing mild cognitive impairment (MCI) and Alzheimer's disease, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). http://medicalxpress.com/news/2011-11-fish-alzheimer-disease.html Health Wed, 30 Nov 2011 03:10:01 EST news241843475 (Medical Xpress) -- The structure of the corpus callosum, a thick band of nerve fibres that connects the two halves of the brain with each other and in this way enables the rapid exchange of information between the left and right hemispheres, plays an important role in the regaining of motor skills following a stroke. A study currently published in the journal Human Brain Mapping has shown that in stroke patients with particularly severely impaired hand movement, this communication channel between the two brain hemispheres in particular was badly damaged. http://medicalxpress.com/news/2011-11-regeneration-requires-intact-channels-halves.html Neuroscience Mon, 21 Nov 2011 10:27:42 EST news241093648 Researchers at UCLA have found a possible explanation for why autistic children act and think differently than their peers.
