Neural networks: Why larger brains are more susceptible to mental illnesses

In humans and other mammals, the cerebral cortex is responsible for sensory, motor, and cognitive functions. A new study shows that the global architecture of the cortical networks in large-brained primates and small-brained rodents is organized by com…

Researchers temporarily turn off brain area to better understand function

Capitalizing on experimental genetic techniques, researchers have demonstrated that temporarily turning off an area of the brain changes patterns of activity across much of the remaining brain.

How the brain improves motor control

Adaptation in reaching — gradual improvement of motor control in response to a perturbation — is a central issue in motor neuroscience. However, even the cortical origin of errors that drive adaptation has remained elusive. Scientists have now shown …

Cerebrospinal fluid signals control the behavior of stem cells in the brain

The choroid plexus, a largely ignored structure in the brain that produces the cerebrospinal fluid, is an important regulator of adult neural stem cells, research indicates. The study also shows that signals secreted by the choroid plexus dynamically c…

HD monkeys display full spectrum of symptoms seen in humans

Transgenic Huntington’s disease monkeys display a full spectrum of symptoms resembling the human disease, strengthening the case that they could be used to evaluate emerging treatments before launching human clinical trials.

Preventive therapy in brain-injured patients lowers risk of pulmonary embolism, DVT

People who sustain a traumatic brain injury (TBI) are at high risk for developing deep vein thrombosis and pulmonary embolism. But blood-thinning medications started within 72 hours of hospital arrival have a significant protective effect against these…
