April Flowers for redOrbit.com - Your Universe Online A team of international researchers, led by Washington University School of Medicine in St. Louis, has created a virtual model of the brain capable of daydreaming like humans do. The computer model is based on the dynamics of brain cells and the many connections those cells make with their neighbors and cells in other brain regions. The team hopes their model will help further understanding of why certain portions of the brain work...

Weizmann Institute scientists discover that spontaneously emerging brain activity patterns preserve traces of previous cognitive activity What if experts could dig into the brain, like archaeologists, and uncover the history of past experiences? This ability might reveal what makes each of us a unique individual, and it could enable the objective diagnosis of a wide range of neuropsychological diseases. New research at the Weizmann Institute hints that such a scenario is within the realm...

Modeling propagating activity waves The appearance of a spot of light on the retina causes sudden activation of millions of neurons in the brain within tenths of milliseconds. At the first cortical processing stage, the primary visual cortex, each neuron thereby receives thousands of inputs from both close neighbors and further distant neurons, and also sends-out an equal amount of output to others. During the recent decades, individual characteristics of these widespread network connections...

For the brain to achieve its intricate functions such as perception, action, attention and decision making, neural regions have to work together yet still retain their specialized roles. Excess or lack of timely coordination between brain areas lies at the core of a number of psychiatric and neurological disorders such as epilepsy, schizophrenia, autism, Parkinson's disease, sleep disorders and depression. How the brain is coordinated is a complex and difficult problem in need of new...
