Bioengineers have compiled a set of recommendations that could significantly reduce concussions and other head injuries in rugby union, having assessed how head impacts and movement vary based on the position on the body where tackles are made. The bioengineers discovered that the risks are not precisely the same for the two groups, as tacklers

Being discharged from a hospital trauma center after receiving treatment for a traumatic brain injury (TBI) does not necessarily mean that a patient has fully recovered. TBI can lead to long-lasting physical and cognitive symptoms, but a new study in JAMA Network Open suggests that many patients may not be receiving follow-up care. Patients in

Are your friends very pain tolerant? Then it is likely that you are as well, provided you are a male. A recent study, published in the Scandinavian Journal of Pain, along with an Editorial Comment by Dr. Jeffrey Mogil, published by De Gruyter, shows that there is a positive correlation between the pain tolerance of

Using male individuals has long been a tradition in scientific mice studies. But new research enforces the importance of using a balanced population of male and female mice. In a paper published May 22 in the journal Cell Reports, scientists studying the locus coeruleus brain structure in mice unexpectedly found substantial differences in the molecular

In a study of mice, National Institutes of Health-funded researchers describe a new circuit involved in fine-tuning the brain’s decision either to hide or confront threats. The study, published in Nature, was partially funded by the NIH’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative. “Being able to manipulate specific circuits can uncover surprising relationships

Neuroscientists have found new evidence on how distinct memories of similar events are represented in the brain. Its findings, which appear in the journal Neuron, correct a previous misconception of how such memories are stored in the hippocampus — a part of the brain crucial for memory and understanding space. “Previous research suggested that brain

Scientists have shone new light on how the human brain uses past experiences and generalizes them to future events, helping us safely navigate the world around us, a study in eLife reveals. Our ability to ‘generalize’ is an important survival technique, but over-generalizing from bad events could explain why some people fear and then avoid

Scientists at The Scripps Research Institute have devised what they call a “neuronal cookbook” for turning skin cells into different types of neurons. As reported today in the journal Nature, the research opens the door to studying common brain conditions such as autism, schizophrenia, addiction and Alzheimer’s disease under reproducible conditions in a dish. “The

Blurry and clear versions of an image are represented similarly in the brain, according to a neuroimaging study published in eNeuro. The research shows how the visual system fills in missing information to maintain perception when visibility is low. Vision arises from a “bottom-up” process that transduces light into neural signals and a “top-down” process

During a stroke or an epileptic seizure, neurons in affected parts of the brain fire at an abnormally rapid rate. One byproduct of this condition is that the pH of the brain drops markedly, rendering the local environment inhospitably acidic. Using a powerful microscopy method called cryo-EM, biologists at Cold Spring Harbor Laboratory (CSHL) have

Neuroscience has studied music for decades, and it has been found to activate both the cortical and deeper brain areas. Neuroscience of dance, instead, is a young but quickly growing field. In her doctoral dissertation, Master of Science Hanna Poikonen developed methods for understanding the processes that dance generates in the cortex at the Cognitive

Starting to play tackle football before age 12 could lead to earlier onset of cognitive and emotional symptoms among athletes who were diagnosed with CTE and other brain diseases postmortem, according to a new study. The findings, from researchers at VA Boston Healthcare System (VABHS) and Boston University (BU) School of Medicine, found that among

If 95 percent of your neighbors are chatty and outgoing, you probably know more about them than the 5 percent who are reclusive and shy. It’s similar for neuroscientists who study the striatum, a brain region associated with action control and learning: they know a lot more about the 95 percent of neurons that communicate

Preliminary research using mcDESPOT magnetic resonance imaging shows changes in the myelin content of white matter in the brain following mild traumatic brain injury. Myelin changes are apparent at the time of injury and 3 months afterward. For more details, see the article, “Prospective study of myelin water fraction changes after mild traumatic brain injury

MIT neuroscientists have developed a new magnetic resonance imaging (MRI) sensor that allows them to monitor neural activity deep within the brain by tracking calcium ions. Because calcium ions are directly linked to neuronal firing — unlike the changes in blood flow detected by other types of MRI, which provide an indirect signal — this

The cerebral neocortex is responsible for higher brain functions, such as conscious thought and language, in humans. In the neocortex, neurons are precisely arranged in an ordered 6-layered structure. This neocortical structure is formed by the sequential generation of billions of neurons and their migration toward the brain surface in the fetal period. “Subplate neurons”

Researchers from the University of California, Irvine, Georgetown University and the University of Rochester have found that specific small molecules in blood plasma may be useful in determining whether someone has sustained a mild traumatic brain injury (mTBI), commonly known as a concussion. The article, “Plasma metabolomic biomarkers accurately classify acute mild traumatic brain injury

Giving opioids to animals to quell pain after surgery prolongs pain for more than three weeks and primes specialized immune cells in the spinal cord to be more reactive to pain, according to a new study by the University of Colorado Boulder. The authors say the paradoxical findings, if replicated in humans, could have far-reaching

In the early days of neuroscience research, scientists painstakingly stained brain cells and drew by hand what they saw in a microscope. Fast forward to 2018 and machines may be able to learn how to do that work. According to a new study in Cell, it may be possible to teach machines how to pick

Modern neuroscience, for all its complexity, can trace its roots directly to a series of pen-and-paper sketches rendered by Nobel laureate Santiago Ramón y Cajal in the late 19th and early 20th centuries. His observations and drawings exposed the previously hidden composition of the brain, revealing neuronal cell bodies and delicate projections that connect individual
