General Knowledge Level Is Associated With Structural Brain Network Connectivity

An individual’s level of general knowledge is associated with structural brain network connectivity, neuroscientists at Ruhr-Universität Bochum and Humboldt-Universität zu Berlin have shown. “Although we can precisely measure the general knowledge of people, and this wealth of knowledge is very important for an individual’s journey through life, we currently know little about the links between […]

Brain Network Structures Can Change Over Time

The connectivity and shape of brain networks — discrete areas of the brain that work together to perform complex cognitive tasks — can alter in fundamental and recurring ways over time, a study led by Georgia State University suggests. The researchers gathered functional magnetic resonance imaging (fMRI) brain imaging data to develop pictures of network […]

Tissue Preserving Technique Enables Single-cell Resolution Maps Of Neural Circuits

MIT chemical engineers and neuroscientists have devised a new way to preserve biological tissue, allowing them to visualize proteins, DNA, and other molecules within cells, and to map the connections between neurons. The researchers showed that they could use this method, known as SHIELD, to trace the connections between neurons in a part of the […]

Sustained Brain Connection Duration Associated With Symptoms Of Autism

The symptoms of autism may result from sustained connections between regions of the brain, researchers at University of Utah Health report. “People with autism do not like unexpected stimuli, and it may be because brains are not as efficient at rapidly shifting between ideas or thoughts. We wondered if we could see how local circuits […]

Brain Activity Pattern May Be Early Sign Of Schizophrenia

Schizophrenia, a brain disorder that produces hallucinations, delusions, and cognitive impairments, usually strikes during adolescence or young adulthood. While some signs can suggest that a person is at high risk for developing the disorder, there is no way to definitively diagnose it until the first psychotic episode occurs. MIT neuroscientists working with researchers at Beth […]
