Artificial neurons on silicon chips that behave just like the real thing have been invented by scientists – a first-of-its-kind achievement with enormous scope for medical devices to cure chronic diseases, such as heart failure, Alzheimer’s, and other diseases of neuronal degeneration. Critically the artificial neurons not only behave just like biological neurons but only… Read more

A group of proteins that help to regenerate damaged nerve cells has been identified by scientists at the German Center for Neurodegenerative Diseases (DZNE). It is commonly accepted that neurons of the central nervous system shut down their ability to grow when they no longer need it; this occurs normally after they have found their… Read more

A new type of cell that keeps time so regularly that it may serve as the brain’s long-hypothesized clock or metronome has been identified by Brown University neuroscientists. This type of neuron spikes rhythmically, and in a synchronized manner, independent of external sensations, said Chris Moore, a professor of neuroscience at Brown and the associate… Read more

For decades, research has shown that our perception of the world is influenced by our expectations. These expectations, also called “prior beliefs,” help us make sense of what we are perceiving in the present, based on similar past experiences. Consider, for instance, how a shadow on a patient’s X-ray image, easily missed by a less… Read more

Researchers at Bar-Ilan University in Israel report a novel and unexpected function of sleep that they believe could explain how sleep and sleep disturbances affect brain performance, aging and various brain disorders. Using 3-D time-lapse imaging techniques in live zebrafish, the researchers were able to define sleep in single-chromosome resolution, and show for the first… Read more
