Research conducted by Maria Ercsey-Ravasz and Zoltan Toroczkai of the University of Notre Dame's Interdisciplinary Center for Network Science and Applications (iCeNSA), along with the Department of Physics and a group of neuroanatomists in France, has revealed previously unknown information about the primate brain. The researchers published an article in the journal Cerebral Cortex showing that the brain is characterized by a highly consistent, weighted network among the functional areas of...

Max Planck scientists can image the processing of information deeper in the cortex with the help of a new multi photon microscope design Visual and tactile objects in our surroundings are translated into a perception by complex interactions of neurons in the cortex. The principles underlying spatial and temporal organization of neuronal activity during decision-making and object perception are not all understood yet. Jason Kerr from Max Planck Institute for Biological Cybernetics in Tbingen,...

Familial hemiplegic migraine is a rare and severe subtype of migraine with aura, an unusual sensory experience preceding the migraine attack. Researchers from the San Raffaele Scientific Institute in Milan, and CNR Institute of Neuroscience in Pisa, Italy, have developed a mouse model of Familial Hemiplegic Migraine type 2 (FHM2) and used it to investigate the migraine's cause. The study will be published on June 23rd in the open-access journal PLoS Genetics. The researchers developed a...

From the Petri dish into a living organism, for the first time U-M scientists observe key aspects of how the brain shapes itself Scientists at the University of Michigan Health System have for the first time demonstrated how memory circuits in the brain refine themselves in a living organism through two distinct types of competition between cells. Their results, published today in Neuron, mark a step forward in the search for the causes of neurological disorders associated with abnormal brain...

(Ivanhoe Newswire) -- Precision tinted lenses have been used widely to reduce visual perceptual distortions in poor readers, and are increasingly used for migraine sufferers, but until now the science behind these effects has been unclear. Researchers have now pinpointed the neurological basis for these visual remedies. The new research shows how colored glasses tuned to each migraine sufferer work by normalizing activity in the brain. The researchers saw specific abnormal brain activity...

Researchers may have found the science behind the effects of precision-tinted lenses on reducing headaches for migraine sufferers, which could significantly help improve treatment options for the debilitating condition. Led by Jie Huang of Michigan State University's Department of Radiology, researchers used functional magnetic resonance imaging (fMRI) to show how "precision-tinted lenses normalize brain activity" in migraine headaches, helping to prevent attacks. The study revealed how...

Precision tinted lenses have been used widely to reduce visual perceptual distortions in poor readers, and are increasingly used for migraine sufferers, but until now the science behind these effects has been unclear. Now research published in the journal Cephalalgia, published by SAGE, uses functional magnetic resonance imaging (fMRI) for the first time to suggest a neurological basis for these visual remedies. The new research shows how coloured glasses tuned to each migraine sufferer work...

Researchers at Mount Sinai School of Medicine have published new data on why the aging brain is less resilient and less capable of learning from life experiences. The findings provide further insight into the cognitive decline associated with aging and neurodegenerative diseases like Alzheimer's. The study is published in the May 25 issue of the Journal of Neuroscience. The Mount Sinai team evaluated the prefrontal cortex"”the part of the brain that controls a wide range of cognitive...

The human brain has yet to explain the origin of one its defining features "“ the deep fissures and convolutions that increase its surface area and allow for rational and abstract thoughts. An international collaboration of scientists from the Yale School of Medicine and Turkey may have discovered humanity's beneficiary "“ a tiny variation within a single gene that determines the formation of brain convolutions "“ they report online May 15 in the journal Nature Genetics. A...

Biologists at UC San Diego have discovered that electrical oscillations in the brain, long thought to play a role in organizing cognitive functions such as memory, are critically important for the brain to store the information that allows us to navigate through our physical environment. The scientists report in the April 29 issue of the journal Science that neurons called "grid cells" that create maps of the external environment in one portion of our brain require precisely timed electrical...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
