Scans reveal astonishingly simple 3D grid structure -- NIH-funded study The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study. The most detailed images, to date, reveal a pervasive 3D grid structure with no diagonals, say scientists funded by the National Institutes of Health. "Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables --...

The first atlas of the surface of the human brain based upon genetic information has been produced by a national team of scientists, led by researchers at the University of California, San Diego School of Medicine and the VA San Diego Healthcare System. The atlas reveals that the cerebral cortex — the sheet of neural tissue enveloping the brain — is roughly divided into genetic divisions that differ from other brain maps based on physiology or function. The genetic atlas...

Belkasoft develops a software toolkit, adapting commercially available brain activity analysis hardware for solving criminal cases. The new product, Belkasoft Mind Analyzer, enables the acquisition of human faces by capturing fMRI data generated by human brain cells. A dedicated facial recognition engine allows reliable identification of acquired faces against a pre-filled database, while the optional Identikit module allows building convincing facial composites. The tool runs in conjunction...

Specialized training of complex motor skills may induce sports-specific structural changes in the human brain A new study, using brain imaging technology, reveals structural adaptations in short-track speed skaters' brains which are likely to explain their extraordinary balance and co-ordination skills. The work by Im Joo Rhyu from the Korea University College of Medicine, and colleagues, is published online in Springer's journal Cerebellum. The cerebellum in the brain plays an...

Weill Cornell scientists say the program might help patients manage their disease Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain. They say their mathematic model can be used to predict where and approximately when an individual patient's brain will suffer from the spread, neuron to neuron, of "prion-like" toxic proteins -- a process they say underlies all forms of...

Portions of a songbird's brain that control how it sings have been shown to decay within 24 hours of the animal losing its hearing. The findings, by researchers at Duke University Medical Center, show that deafness penetrates much more rapidly and deeply into the brain than previously thought. As the size and strength of nerve cell connections visibly changed under a microscope, researchers could even predict which songbirds would have worse songs in coming days. "When hearing was lost,...

If you are looking for a particular object – say a yellow pencil – on a cluttered desk, how does your brain work to visually locate it? For the first time, a team led by Carnegie Mellon University neuroscientists has identified how different neural regions communicate to determine what to visually pay attention to and what to ignore. This finding is a major discovery for visual cognition and will guide future research into visual and attention deficit disorders. The study,...
