Call them the Brain Generation -- the students working toward degrees in neuroscience, who have grown up in a time when exciting new discoveries about the brain come out every day. But they’re also worried about their futures – which has led top senior neuroscientists to publish recommendations about how neuroscience education must change.
The relentless desire by mice to run on cage “exercise” wheels has helped explain at a molecular level how exercise benefits a mammal’s brain.
A dietary supplement containing a blend of thirty vitamins and minerals—all natural ingredients widely available in health food stores—has shown remarkable anti-aging properties that can prevent and even reverse massive brain cell loss, according to new research from McMaster University. It’s a mixture scientists believe could someday slow the progress of catastrophic neurological diseases such as Alzheimer’s, ALS and Parkinson’s.
Researchers have long known that sex hormones such as estrogen play a role in migraine. But there’s been little research on how that works. Do women with migraine have higher estrogen levels in general? Higher levels at the peak of the monthly cycle?
Employees (or shift workers), who punch in for graveyard or rotating shifts, are more prone to numerous health hazards, from heart attacks to obesity, and now, new research, published in Endocrinology, shows shift work may also have serious implications for the brain.
Scientists at the University of Liverpool have discovered that muscle cells affected by muscular dystrophy contain high levels of an enzyme that impairs muscle repair. This finding provides a new target for potential drug treatments for the disease, which currently has no cure.
Brian Balin, PhD, has studied the link between infection and Alzheimer's disease for more than 20 years and offers his thoughts on this growing area of research.
A new mouse model, developed by researchers at the University of Wisconsin–Madison, is the first to show that when more of a specific biological molecule moves between different parts of nerve cells in the mouse brain, it can lead to behaviors that resembles some aspects of autism spectrum disorder (ASD) in humans.
Drug-cue associations can have a powerful influence over individuals with drug and alcohol use disorders, often leading to relapse in those attempting to stay abstinent. Few studies have investigated how drugs affect learning or memory for drug-associated stimuli in humans. This study examined the direct effects of alcohol on memory for images of alcohol-related beverages, such as beer bottles or liquor glasses, or neutral beverages, such as water bottles or soda cans, in social drinkers.
While most people will agree that excessive consumption of alcohol can have a detrimental effect on the brain, there is less agreement regarding the effects of light or moderate drinking. This includes concern and controversy surrounding the effects of drinking on the development of neurodegenerative diseases such as Alzheimer’s (AD). This study investigated the association between consumption of different alcoholic beverages – beer, wine, and spirits – and one of the neuropathological signs of Alzheimer’s disease, β-amyloid (Aβ) aggregation in the brain.
The new study found that children with high-functioning autism spectrum disorder integrated in regular schools find it difficult to perform writing tasks. This can impair their academic achievements, social availability, and self-confidence. Prof. Sara Rosenblum, who authored the study, comments: “The education system addresses reading skills, but there is insufficient attention to writing skills

Evidence is mounting that a diet mimicking the effects of fasting has health benefits beyond weight loss, with a new USC-led study indicating that it may reduce symptoms of multiple sclerosis.
When nerve cells have to communicate with each other in our brains, it involves release of small signal molecules, the so-called neurotransmitters, which act as chemical messengers in specific points of contact between nerve cells, called synapses. Here the released neurotransmitter is bound and registered by receptors at the surface of the receiving nerve cell. This will, in turn, trigger a signal which is sent on to other nerve cells.
A neurosurgeon who specializes in deep brain stimulation (DBS) is seeking a target in the brains of bi-polar disorder patients for possible DBS implantation to provide help to them.
A study from The Scripps Research Institute suggests external stimulation guides certain neurons’ early development so that inhibitory neurons split into two different types of neurons, each with a different job, adding another level of complexity and regulation to the brain’s circuitry.
Johns Hopkins researchers report they have inadvertently found a way to make human muscle cells bearing genetic mutations from people with Duchenne muscular dystrophy.
After eating a meal, you can thank your vagus nerve for sensing and signaling that feeling of fullness to your brain. That same nerve also detects nutrients and controls digestion. The vagus has long been recognized as a remarkable internal sensory system, regulating breathing and heart rate among other functions. Yet how it receives the information it uses to perform these tasks has been less well-known.
UTHealth’s Mobile Stroke Unit —the nation’s first — is one of many ways the UT System’s 14 health and academic institutions are fighting stroke through research, technology and patient care.
