Study shows cocaine use in mice leads to formation of synapses

Drugs of abuse, like cocaine, are so addictive due in part to their cellular interaction, creating strong cellular memories in the brain that promote compulsive behaviors.

Study reveals how the loss of a protein affects proper brain development

Normal brain development requires a precise interplay between neuronal and non-neuronal (also called glial) cells. In a new study, researchers from the University of Tsukuba revealed how the loss of protein arginine methyltransferase (PRMT) 1 causes disruptions in glial cells and affects proper brain development.

Star-shaped brain cells are essential for blood-brain barrier health, shows study

Hard skulls help protect our brains from physical injuries.In addition to a tough outer shell, brains have internal defenses, including a powerful shield called the blood-brain barrier that defends brain cells from substances in the bloodstream that are toxic and dangerous to nerve cells. If the blood-brain barrier is breached, then health problems arise.

Study shows how neurons communicate when confronted with stroke

Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans School of Medicine, and Ludmila Belayev, MD, LSU Health New Orleans Professor of Neuroscience, Neurology and Neurosurgery, has unlocked a key fundamental mechanism in the communication between brain cells when confronted with stroke.

Boosting metabolic resources in the brain could be a way to slow neurodegeneration

Researchers at Vanderbilt University Medical Center have shown for the first time that when one optic nerve in the eye is damaged, as in glaucoma, the opposite optic nerve comes to the rescue by sharing its metabolic energy.

Study shows the negative impacts of cannabis use

Constant exposure to cannabis could have an adverse effect on sociability. According to studies, in certain indviduals, such exposures may result in reduced social interactions and withdrawal symptoms.

Genetic dysfunction of brain astrocytes promotes head pain in familial migraine

Neuroscientists of the University of Zurich shed a new light on the mechanisms responsible for familial migraine: They show that a genetic dysfunction in specific brain cells of the cingulate cortex area strongly influences head pain occurrence.

Stem cell model sheds new light on neurodegeneration process

A new study published today in Neuron led by The New York Stem Cell Foundation Research Institute's Valentina Fossati, Ph.D., creates astrocytes - an integral support cell in the brain - from stem cells and shows that in disease-like environments, these normally helpful cells can turn into neuron-killers.

Largest proteomic study reveals link between glucose metabolism proteins and AD biology

In the largest study to date of proteins related to Alzheimer's disease, a team of researchers has identified disease-specific proteins and biological processes that could be developed into both new treatment targets and fluid biomarkers.
