Research results reported in Restorative Neurology and Neuroscience Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves. Their results are...

Newly clarified function of 'indirect pathways' from brain to spinal motor neurons, controlling dexterous hand movements by newly developed 'the double viral vector transfection technique' The collaborative research team led by Professor Tadashi ISA, Project Assistant Professor Masaharu KINOSHITA from The National Institute for Physiological Sciences, The National Institutes of Natural Sciences and Fukushima Medical University and Kyoto University, developed "the double viral vector...

Young Birds Use Their Brain To Learn Songs

Brett Smith for RedOrbit.com Male songbirds use a versatile part of the brain to learn their father´s song during the early stages of development, according to a report published yesterday in the online version of Nature. Researchers at the University of California at San Francisco (UCSF) found that Bengalese finch males use a trial-and-error method in learning the song they will use to attract a mate once they reach maturity. The learning process begins around 40 days after...

A study by a new member of the Medical Faculty of the University of Geneva and a group of American researchers opened a novel window on the neuronal circuits involved What happens at the level of individual neurons while we learn? This question intrigued the neuroscientist Daniel Huber, who recently arrived at the Department of Basic Neuroscience at the UNIGE. During his stay in the United States, he and his team tried to unravel the network mechanisms underlying learning and memory at the...

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,...

A team of physicians and scientists at Barrow Neurological Institute, in collaboration with colleagues in the Ukraine, have written a first-of-its-kind biography of Ukranian anatomist and histologist Vladimir Betz. The article, "The Discovery of the Pyramidal Neurons: Vladimir Betz and a New Era of Neuroscience," appears in the November 2011 issue of the medical journal, Brain. Among other contributions, Vladimir Alekseyevich Betz (1834-1894) is best known for his discovery of Betz cells,...

In a first ever demonstration of a two-way interaction between a primate brain and a virtual body, two monkeys trained at the Duke University Center for Neuroengineering learned to employ brain activity alone to move an avatar hand and identify the texture of virtual objects. "Someday in the near future, quadriplegic patients will take advantage of this technology not only to move their arms and hands and to walk again, but also to sense the texture of objects placed in their hands, or...

New study shows auditory-motor integration located in a different part of the brain Hearing Beethoven while reciting Shakespeare can suppress even a King's stutter, as recently illustrated in the movie "The King's Speech". This dramatic but short-lived effect of hiding the sound of one's own speech indicates that the integration of hearing and motor functions plays some role in the fluency (or dysfluency) of speech. New research has shown that in adults who have stuttered since childhood the...

The voluntary movements we make must be "prepared" in our brain before they are executed. However, be it perfect timing, a false-start, or a delayed reaction, the neural circuitry underlying movement preparation is not well understood. Now a new study provides intriguing insight into how a neural circuit forms a motor plan. The research, published by Cell Press in the August 11 issue of the journal Neuron, uses a new type of analysis to assess the moment-by-moment firing rate of neurons in...

(Ivanhoe Newswire) "“ If you usually have a hard time picking up the latest dance moves or learning to play a new piano piece, it could be due to a lack of GABA, a chemical messenger in the brain. People who are fast to learn a simple sequence of finger motions are also those whose brains show large changes in GABA following electrical stimulation. GABA is important for the plasticity of the morot cortex, a brain region involved in planning, control, and execution of voluntary...
