Mice With MS-Like Condition Walk Again After Human Stem Cell Treatment
Mice severely disabled by a multiple sclerosis (MS)- like condition could walk less than two weeks following treatment with human stem cells. The finding, which uncovers new avenues for treating MS, is published online, in the journal Stem Cell Reports.
Mechanism offers new insight into opening & closing the blood-brain barrier
Like a bouncer at an exclusive nightclub, the blood-brain barrier allows only select molecules to pass from the bloodstream into the fluid that bathes the brain. Vital nutrients get in; toxins and pathogens are blocked.
Antidepressant may slow Alzheimer's disease
A commonly prescribed antidepressant can reduce production of the main ingredient in Alzheimer's brain plaques, according to new research at Washington University School of Medicine in St. Louis and the University of Pennsylvania.
New treatment for neuropathy? How cone snail venom minimizes pain
The venom from marine cone snails, used to immobilize prey, contains numerous peptides called conotoxins, some of which can act as painkillers in mammals. A recent study in The Journal of General Physiology provides new insight into the mechanisms by which one conotoxin, Vc1.
Researchers Show Human Learning Altered by Electrical Stimulation of Dopamine Neurons
Stimulation of a certain population of neurons within the brain can alter the learning process, according to a team of neuroscientists and neurosurgeons at the University of Pennsylvania. A report in the Journal of Neuroscience describes for the first time that human learning can be modified by stimulation of dopamine-containing neurons in a deep brain structure known as the substantia nigra.
Difference Found in Brain Area Linked to Memory Among College Football Players
Preliminary research finds that within a group of collegiate football players, those who experienced a concussion or had been playing for more years had smaller hippocampal volume (an area of the brain important for memory) than those with fewer years of football experience, according to a study in the May 14 issue of JAMA.
New stem cell research points to early indicators of schizophrenia
Using new stem cell technology, scientists at the Salk Institute have shown that neurons generated from the skin cells of people with schizophrenia behave strangely in early developmental stages, providing a hint as to ways to detect and potentially treat the disease early.
Alternative pathways let right and left communicate in early split brains
During the last century, many patients have undergone a variety of brain surgeries in an attempt to alleviate all sorts of psychiatric maladies, from hysteria and depression (mainly in women) to schizophrenia and epilepsy.
Brain may never fully recover from exposure to paint, glue, degreasers
People who are exposed to paint, glue or degreaser fumes at work may experience memory and thinking problems in retirement, decades after their exposure, according to a study published in the May 13, 2014, print issue of Neurology, the medical journal of the American Academy of Neurology.
Study examines association between small-vessel disease, Alzheimer pathology
Cerebral small-vessel disease (SVD) and Alzheimer disease (AD) pathology appear to be associated.
