Structure of brain networks is not fixed, study finds

The shape and connectivity of brain networks—discrete areas of the brain that work together to perform complex cognitive tasks—can change in fundamental and recurring ways over time, according to a study led by Georgia ...

Novel brain map tracks early brain atrophy from HIV infection

A new map of brain tissue in people with HIV shows atrophy in several areas including a primary neurocognitive control center where shrinkage and loss of function can be seen in scans before clinical symptoms appear.

Detailed atlas of the nervous system

Researchers at Karolinska Institutet have created a systematic and detailed map of the cell types of the mouse nervous system. The map, which can provide new clues about the origin of neurological diseases, is presented in ...

Brain map sheds light on smokers' habit

Smokers may be predisposed to their habit because of the molecular make-up of their brain, research suggests. The finding comes from a new brain map that helps explain why certain behaviours are linked with particular areas ...

Brain scans detect Alzheimer's before onset of symptoms

Researchers in New Mexico and Croatia have used a brain scanning technique known as magnetoencephalography, or MEG, to search for a new biological fingerprint of Alzheimer's disease. The results of the study are published ...

Three reasons to think twice about mapping the brain

The brain has a geography that matters. The cerebral cortex (the grey outer layer of the brain) is folded into our skulls in such a way as to reduce the wiring length of our neurons and improve cognitive function. Needless ...

Study examines drowning-induced brain injury in children

A new study indicates that children who develop brain injury due to non-fatal drowning often experience severe motor deficits but maintain relatively intact perceptual and cognitive capabilities.
