Max-Planck-Gesellschaft Listening abilities depend on rhythms in the brain Naturally, our brain activity waxes and wanes. When listening, this oscillation synchronizes to the sounds we are hearing. Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences have found that this influences the way we listen. Hearing abilities also oscillate and depend on the exact timing of one’s brain rhythms. This discovery that sound, brain, and behavior are so intimately coupled...
Rats’ neurons reveal steady neural network coordination regardless of the animals’ behavior A team of Brazilian physicists working with neuroscientists studying freely behaving rats have found that their neurons often act in precise coordination over time, in a study about to be published in EPJ B. These findings stem from the work of Bruno Silva, a researcher at Bahia Federal University in Salvador, and his colleagues from other universities in the Northeastern region of Brazil, and...
April Flowers for redOrbit.com - Your Universe Online Even the most intelligent, complex brains can be taken by a swindler's story, a new study from Case Western Reserve University shows, even stories that prove false upon a second look. The new study, published online in the journal NeuroImage, reveals that when the brain fires up the network of neurons that allows a person to empathize, the network used for analysis is suppressed. Our ability to appreciate the human cost of our action...
A team of neuroscientists have proposed a new and potentially revolutionary way of determining the neuronal connectivity (the "connectome") of the whole brain of the mouse, in an essay published October 23 in the open access journal PLOS Biology. The team, led by Professor Anthony Zador, Ph.D. of Cold Spring Harbor Laboratory, aims to provide a comprehensive account of neural connectivity. At present the only method for obtaining this information with high precision relies on examining...
SAN DIEGO and TARRYTOWN, New York, July 16, 2012 /PRNewswire/ -- Afraxis and PsychoGenics today announced an alliance to offer Afraxis' Enhanced Spine Platform (ESP) technology as part of PsychoGenics' comprehensive testing capabilities and drug discovery services. ESP rapidly assesses the quantity, morphology and maturity of dendritic spines, structures that mediate signaling in neural synapses, and can be used to evaluate disease models and in vivo preclinical efficacy and safety...
Michael Harper for redOrbit.com Google is alive. Rather, they’ve connected 16,000 computers in a neural network, brought it to life, and has let it loose on the internet to “learn.” Brought to you by the same secretive lab which brought us things like self-driving cars and Project Glass, this new project is designed to create a working simulation of the human brain, which means it will watch as it learns. Of course, when you create a giant learning brain, the first thing you do...
A molecule responsible for the proper formation of a key portion of the nervous system finds its way to the proper place not because it is actively recruited, but instead because it can't go anywhere else. Researchers at Baylor College of Medicine have identified a distal axonal cytoskeleton as the boundary that makes sure AnkyrinG clusters where it needs to so it can perform properly. "It has been known that AnkyrinG is needed for the axon initial segment to form. Without the axon...
University of Georgia researchers have developed a map of the human brain that shows great promise as a new guide to the inner workings of the body's most complex and critical organ. With this map, researchers hope to create a next-generation brain atlas that will be an alternative option to the atlas created by German anatomist Korbinian Brodmann more than 100 years ago, which is still commonly used in clinical and research settings. Tianming Liu, assistant professor of computer...
Microsoft co-founder Paul Allen has donated $300 million in order to create a center that will study the brain and learn more about exactly how the human mind works, the Allen Institute for Brain Science announced Wednesday. The latest donation brings the amount of money that the 59-year-old businessman, investor and philanthropist has invested in the institute which was named in his honor to $500 million, Forbes staff writer Matthew Herper said. According to Herper and the Wall Street...
Researchers track structural changes during formation of new memories New connections between brain cells emerge in clusters in the brain as animals learn to perform a new task, according to a study published in Nature on February 19 (advance online publication). Led by researchers at the University of California, Santa Cruz, the study reveals details of how brain circuits are rewired during the formation of new motor memories. The researchers studied mice as they learned new behaviors,...
