How dopamine drives brain activity

Using a specialized magnetic resonance imaging (MRI) sensor that can track dopamine levels, neuroscientists have discovered how dopamine released deep within the brain influences distant brain regions.

Spina bifida surgery before birth restores brain structure

Surgery performed on a fetus in the womb to repair defects from spina bifida triggers the body’s ability to restore normal brain structure, new research has discovered.

Where in the brain does creativity come from? Evidence from jazz musicians

A new brain-imaging study has studied the brain activity of jazz guitarists during improvisation to show that creativity is, in fact, driven primarily by the right hemisphere in musicians who are comparatively inexperienced at improvisation. However, m…

Visual feedback enhances activation of muscle movement in response to bodily sensation

Visual feedback is just as important as a sense of body position when it comes to the involuntary reflexes that activate muscle movement, says a new study.

Amyloid formation drives brain tissue loss in animal studies

Amyloid plaque formation directly causes brain tissue loss in animals, but a drug called lithium reduces the life shortening effects of this loss, shows a new study.

Alcohol consumption by fathers before conception could negatively impact child development

Trouble for alcoholic fathers, hope for alcoholic mothers. Scientists have explored the relationship between parental alcohol consumption — before conception in the case of fathers and during pregnancy in the case of mothers — and offspring developme…

How stress remodels the brain

Stress restructures the brain by halting the production of crucial ion channel proteins, according to research in mice.

Cellular train track deformities shed light on neurological disease

A new technique allows researchers to test how the deformation of tiny train track-like cell proteins affects their function. The findings could help clarify the roles of deformed ‘microtubules’ in traumatic brain injuries and in neurological diseases …

Worldwide scientific collaboration unveils genetic architecture of gray matter

For the first time, more 360 scientists from 184 different institutions have contributed to a global effort to find more than 200 regions of the genome and more than 300 specific genetic variations that affect the structure of the cerebral cortex and l…

Brain mapping study suggests motor regions for the hand also connect to the entire body

Investigators report that they have used microelectrode arrays implanted in human brains to map out motor functions down to the level of the single nerve cell. The study revealed that an area believed to control only one body part actually operates acr…
