Computer scientists at Brown University have created software to examine neural circuitry in the human brain. The 2-D neural maps combine visual clarity with a Web-based digital map interface, and users can view 2-D maps together with 3-D images. The program aims to better understand myelinated axons, which have been linked to pathologies such as autism. Results are published in IEEE Transactions on Visualization and Computer Graphics. Medical imaging systems allow neurologists to summon 3-D...
Neural Technologies announced the launch of a software program designed to intelligently identify potential fraudulent claims made to state and federal health care programs. The real-time fraud detection program can identify unique markers and call attention to processors before a payment is made - in many instances, potential overpayments are identified and eliminated during the initial billing phase. (PRWEB) May 25, 2011 Neural Technologies announced the launch of a software program...
A team based in Pitt's Swanson School of Engineering produced and observed the extended electrical charge associated with working memory using living-cell models of neural networks that reveal the complex, diminutive world of brain cells University of Pittsburgh researchers have reproduced the brain's complex electrical impulses onto models made of living brain cells that provide an unprecedented view of the neuron activity behind memory formation.The team fashioned ring-shaped networks of...
In the wild, mammals survive because they can see and evade predators lurking in the shadowy bushes.That ability translates to the human world. Transportation Security Administration screeners can pick out dangerous objects in an image of our messy and stuffed suitcases. We get out of the house every morning because we find our car keys on that cluttered shelf next to the door.This ability to recognize target objects surrounded by distracters is one of the remarkable functions of our nervous...
F1000 Biology Reports takes a look at the story behind the invention of optogeneticsCommenting on Edward Boyden's article, Ben Barres, Head of the Neuronal & Glial Cell Biology Section of Faculty of 1000 and Professor at Stanford University School of Medicine said: "There will probably be a Nobel prize for optogenetics someday as it has revolutionized our attempts to understand how the brain works. This article provides a fascinating insight into the birth of optogenetics and the...
Artificial neural network model proves accurate in classification studyIrrigating agricultural crops places huge demands on water resources around the globe. In Spain for instance, where agriculture is a major contributor to the nation's economy, 85% of country's total water demand comes from the agricultural sector. The excessive use of irrigation water has resulted in serious environmental concerns in Mediterranean countries, where rising demand has deteriorated groundwater resources,...
Everyone would like MDs to have the best education "“ and to absorb what they are taught. The lead article in the April 4 issue of the journal Academic Medicine* connects research on how the brain learns to how to incorporate this understanding into real world education, particularly the education of doctors."Repetition, reward, and visualization are tried and true teaching strategies. Now, knowing what is happening in the brain will enhance teaching and learning," said Michael J....
Easier data sharing and integration has the potential to transform collaborative researchModern brain research generates immense quantities of data across different levels of detail, from gene activity to large-scale structure, using a wide array of methods. Each method has its own type of data and is stored in different databases. Integrating findings across levels of detail and from different databases, for example to find a link between gene expression and disease, is therefore challenging...
Surprising rate at which neuronal networks in the cerebral cortex delete sensory information The dynamics behind signal transmission in the brain are extremely chaotic. This conclusion has been reached by scientists from the Max Planck Institute for Dynamics and Self-Organization at the University of Göttingen and the Bernstein Center for Computational Neuroscience Göttingen. In addition, the Göttingen-based researchers calculated, for the first time, how quickly information stored...
Population of Highly Active Neurons Could Provide Insight Into the NeocortexCarnegie Mellon University researchers have found that within the brain's neocortex lies a subnetwork of highly active neurons that behave much like people in social networks. Like Facebook, these neuronal networks have a small population of highly active members who give and receive more information than the majority of other members, says Alison Barth, associate professor of biological sciences at Carnegie Mellon...
