Research reveals circuit that clarifies how stress exacerbates pain and meditation eases it
Enkephalins are peptides that are produced in response to certain stimuli — such as stress, fear or pain — that also have potent painkilling properties.
Sleep deprived suffer performance loss, according to new study
Lack of sleep definitely affects your performance the next day, and probably for a longer period of time than you might expect, according to a new study.
New study hints at why infamous gene variant increases odds of developing Alzheimer’s disease
A substance called A-beta, is strongly and broadly believed to play a major role in the Alzheimer’s disease’s pathology.
Toxic brain cells may drive many neurodegenerative disorders, Stanford-led study finds
Astrocytes, the brain’s most abundant cells, are essential to the survival and healthy function of nerve cells. But aberrant astrocytes may be driving brain disorders.
Jekyll & Hyde tale unfolding within the human brain may explain neurodegenerative disease
Judging from the very terms used to designate brain research — neuroscience, neurology, neurobiology — you might figure nerve cells (or neurons) are the only cells in the brain worth knowing about or, the only cells resident in that organ.
Researchers identify source of opioids’ side effects
Stanford researchers said they have identified the receptors to which opioid drugs bind to produce tolerance and increased sensitivity to pain, as well as a commercially available drug that limited those side effects in mice.
Space travelers beware: High-speed solar protons may mess up your hashish high
Stanford neuroscientist Ivan Soltesz, PhD, is a very serious researcher with a focus on the causes of, and treatments for, chronic epileptic seizures in children.
Research locates absence epilepsy seizure ‘choke point’ in brain
Stanford researchers used a rodent model to discover that shifting the firing pattern of a particular set of brain cells is all it takes to initiate, or to terminate, an absence seizure.
“Choke point” for most-common form of childhood epilepsy identified
Epilepsy, a pattern of recurrent seizures, affects 1 in 26 people over their lifetime. So-called absence epilepsy (also called petit mal seizures) is most common among children ages 6 to 15 and accounts for about 1 in 20 epilepsy cases.
Portions of the brain fall asleep and wake back up all the time, Stanford researchers find
New research finds that small regions of the brain cycle in and out of sleep, even when awake. The cycles shift toward “awake” when that part of the brain pays attention to a task.
Paying attention is a matter of making the brain a little more awake
It turns out that tiny little bits of our brains are constantly cycling in and out of sleep, and when those few cells are down, they miss things. What’s more, when neurons are specifically paying attention, they spend less time in the sleepy part of the c
More of a single chemical in a single brain region means better mental juggling
Like a computer’s RAM, working memory serves as a buffer where information, derived from the senses or retrieved from long-term memory, can be temporarily placed so the conscious brain can process it.
More GABA in one brain region linked to better working memory
The amount of a neurotransmitter called GABA in the dorsolateral prefrontal cortex predicted individuals’ ability to keep several things in mind simultaneously, researchers found.
Stanford scientists discuss the “hard problem” of consciousness with playwright Tom Stoppard
Tom Stoppard’s latest play, which tackles issues of neuroscience and consciousness – leading to its title, “The Hard Problem” – was followed by a panel discussion with scientists from Stanford and the University of California, Berkeley.
Using brain scans and personal history to predict best antidepressant choice
Stanford neuroscientist Leanne Williams, PhD, has focused her research career on how insights from brain science can help improve care for people with psychiatric conditions.
Blues progression: From a dye to a placebo to an Alzheimer’s treatment?
Big pharmaceutical companies have gradually abandoned their one time obsession with ridding Alzheimer’s patients’ brains of gummy extracellular deposits known as amyloid plaques (they’re composed of a protein called beta-amyloid) that characterize the dis
Technology for typing with brain signals could allow paralyzed people to communicate
Engineer Krishna Shenoy, PhD, and graduate student (and then postdoctoral fellow) Paul Nuyujukian, MD, PhD, have updated the algorithms for how they translate the brain signals into typing, which they tested in a series of studies.
Brain-sensing technology developed by Stanford scientists allows typing at rate of 12 words per minute
Technology for reading signals directly from the brain developed by Stanford Bio-X scientists could provide a way for people with movement disorders to communicate.
LRRKing in the shadows: Likely hidden pathological mechanism of Parkinson’s disease
Parkinson’s disease, the second-leading neurodegenerative disorder after Alzheimer’s disease, affects one in every 60-70 Americans age 65 or older.
