Scientists decode brain signals nearly at speed of perception

Using electrodes implanted in the temporal lobes of awake patients, scientists have decoded brain signals at nearly the speed of perception. Further, analysis of patients' neural responses to two categories of visual stimuli ...

Myelin cells swing along blood vessels to traverse the brain

The cells that create myelin, a fatty material that insulates nerve fibers in the brain's white matter, migrate into the developing brain by climbing and swinging on blood vessels, according to new research led by UC San ...

Thalamus found to add contextual information to visual signals

The thalamus not only relays visual signals from the eye to the visual cortex as previously thought, but also conveys additional, contextual information. Integrating these different signals is essential to understand and ...

Signaling pathway suppresses brain tumors

Researchers at the University of Basel took a close look at a signaling pathway present in most organisms and found that it suppresses the formation of specific types of brain tumor. Their results have been published by the ...

A network of artificial neurons learns to use human language

A group of researchers from the University of Sassari (Italy) and the University of Plymouth (UK) has developed a cognitive model, made up of two million interconnected artificial neurons, able to learn to communicate using ...

The brain forgets in order to conserve energy

Our brains not only contain learning mechanisms but also forgetting mechanisms that erase "unnecessary" learning. A research group at Lund University in Sweden has now been able to describe one of these mechanisms at the ...
