by University of North Carolina Health Care Credit: Pixabay/CC0 Public DomainA collaborative research endeavor by scientists in the Departments of Radiology, Neurology, and Psychology and Neuroscience at the UNC School of Medicine have demonstrated the deleterious effects of chronic cocaine use on the functional networks in the brain. Their study titled “Network Connectivity Changes Following Long-Term...
by Massachusetts Institute of Technology A) Neural field model and connections. Neural fields provided a quantitative way to describe each ensemble’s patterns of activity across simultaneously recorded sites. The same model can describe different ensembles. Each electrode occupies a position on a cortical manifold (line) Δ parameterized by the variable x and is connected to all...
by Jennifer Brown, University of Iowa Credit: Pixabay/CC0 Public Domain A new study that links the location of brain injury to levels of depression in patients following the injury has identified two distinct brain networks; one associated with increased depression symptoms and one associated with decreased depression symptoms. The large-scale study led by researchers with...
by Ingrid Fadelli , Medical Xpress Credit: Pixabay/CC0 Public Domain Neuroscientists have been trying to understand for decades how the human brain changes over the lifespan. This could ultimately help to devise more effective treatments for neurological and cognitive disorders primarily observed in the elderly. Researchers at Drexel University and Villanova University have recently carried...

Credit: Carles Bosch Researchers at the Francis Crick Institute have developed an imaging technique to capture information about the structure and function of brain tissue at subcellular level—a few billionths of a meter, while also capturing information about...
by University of Cambridge Credit: CC0 Public Domain People with dementia struggle to adapt to changes in their environment because of damage to areas of the brain known as “multiple demand networks,” highly-evolved areas of the brain that support general intelligence, say scientists at the University of Cambridge. There are many different types of dementia,...
INSTITUTE OF PHYSICAL CHEMISTRY OF THE POLISH ACADEMY OF SCIENCES Dopamine, serotonin, adrenalin… The smooth functioning of the human brain depends on their correct proportions. Any disturbances mean diseases. That’s why it’s so important to be able to detect these disturbances as early as possible – before the appearance of any visible symptoms. This will...
by Georgia State University 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 State University. The interaction and communication among neurons, known as “functionally connectivity,” gives rise to brain networks. Researchers...
VANDERBILT UNIVERSITY MEDICAL CENTER Successful epilepsy surgery can improve brain connectivity similar to patterns seen in people without epilepsy, according to a new study published in the journal Neurosurgery. The Vanderbilt University Medical Center (VUMC) study of 15 people with temporal lobe epilepsy is the first to show improvements in brain networks after surgery compared to a group of healthy subjects. Brain networks involved...
Utilizing lesion network mapping, a recently developed technique for analyzing how the brain works, Ryan Darby, MD, assistant professor of Neurology at Vanderbilt, studied free will perception related to movement decisions. A diagram showing the regions associated with disorders of agency and volition, two components comprising free will. Credit: PNAS In the study, published online...
