Our brains make contextual decisions in an instant; the mystery is how. In a new study, a team of neuroscientists and engineers delve into this decision-making process and report some findings that confound the conventional scientific wisdom.
The pain caused by a surgical incision may contribute to the risk of postoperative cognitive dysfunction, a sometimes transient impairment in learning and memory that affects a small but significant number of patients in the days following a surgical procedure.
There was an audible gasp at the New York Stem Cell Foundation (NYSCF) conference recently when neurosurgeon Ivar Mendez showed a video of a Parkinson’s patient before and after a transplant of a fetal stem-cell like graft. The patient was affectless, and could barely move before the graft. Eight years later, he was animated and moving briskly.
People who speak more than one language and who develop dementia tend to do so up to five years later than those who are monolingual, according to a study.
A growing body of evidence suggests that the brain plays a key role in glucose regulation and the development of type 2 diabetes, according to a new study.
Eye contact during early infancy may be a key to early identification of autism, according to a new study, which revealed the earliest sign of developing autism ever observed- a steady decline in attention to others’ eyes within the first two to six months of life.
This fall, Harvard University regenerative biologist Amy Wagers hooked up the circulatory systems of mice with multiple sclerosis (MS) to those of young healthy mice. She and a global team found that factors in the young blood prompted anti-inflammatory immune cell formation. This, in turn, actually regenerated the dying myelin sheaths wrapped around neuronal axons that are the very signature of MS.
New research has found that people experiencing depressive episodes display increased brain activity when they think about themselves.
Using brain-wide and consistent tracer data, the researchers proposed a novel understanding of brain architecture using a network representation of connections within the primate cortex.
A stem cell therapy previously shown to reduce inflammation in the critical time window after traumatic brain injury also promotes lasting cognitive improvement, according to preclinical research led by Charles Cox, MD, at The University of Texas Health Science Center at Houston (UTHealth) Medical School.
Researchers have found that a gene already implicated in human speech disorders and epilepsy is also needed for vocalizations and synapse formation in mice.
Researchers have developed a computerized system that can track patients’ brain activity during a coma and automatically adjust drug dosages to maintain the correct state.
Five decades of isolation, military rule and woeful health care have left Myanmar with a particularly high rate of blindness. Now, the veil of darkness is starting to lift, thanks in part to a surgical procedure that allows cataracts to be removed safely, without stitches, through two small incisions.
Imitation may be the sincerest form of flattery for adults, but for babies it’s their foremost tool for learning. Researchers have found the first evidence revealing a key aspect of the brain processing that occurs in babies to allow this learning by observation.
A team of scientists created and characterized a new molecule, using elements of Clostridium botulinum and Clostridium tetani neurotoxins, that was able to alleviate hypersensitivity to inflammatory pain.
Imagine a 1950s horror movie monster— a creeping, gelatinous, gluey tangle of gunk that strangles everything around it. That’s what amyloid plaques are like when they form in body tissues.
A research team demonstrated, for the first time, delivery of a drug that turns off a critical gene in the aggressive and incurable glioblastoma multiforme, increasing survival rates significantly in animals with the deadly disease.
Video gaming causes increases in the brain regions responsible for spatial orientation, memory formation and strategic planning, as well as fine motor skills, according to a new study.
Growing up in poverty can have long-lasting, negative consequences for a child. But for poor children raised by parents who lack nurturing skills, the effects may be particularly worrisome, according to a new study that shows children living in poverty exhibit changes in the brain that can lead to lifelong problems.
A new study questions previous suggestions that attention deficit hyperactivity disorder (ADHD) is the result of fundamental abnormalities in dopamine transmission, and suggests that the main cause of the disorder may lie instead in structural differences in the grey matter in the brain.
A brain chemical that desynchronizes the cells in the biological clock helps the clock adjust more quickly to abrupt shifts in daily light/dark schedules such as those that plague modern life.
Imagine significantly reducing a persistent migraine or fibromyalgia by a visit to a doctor who delivers low doses of electricity to the brain. Scientists are optimizing the next generation for such a technique, called high-definition transcranial direct current stimulation, or HD-tDCS.
Light enhances brain activity during a cognitive task even in some people who are totally blind, according to a new study. The findings contribute to scientists' understanding of everyone's brains, as they also revealed how quickly light impacts on cognition.
Borrowing a tactic used to identify lung infections, researchers have discovered a potential method to identify traumatic brain injuries that uses positron emission tomography scans and the body’s immune response to a brain injury.
Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now, researchers have shown that these dendrites do more than relay information from one neuron to the next.
