In the future, treating a concussion could be as simple as cooling the brain. That's according to research conducted by University of Wisconsin-Madison engineers, whose findings support the treatment approach at the cellular level.
In a new study published in GLIA , Virginia Tech neuroscientists at the Fralin Biomedical Research Institute at VTC describe how the common Toxoplasma gondii parasite prompts the loss of inhibitory signaling in the brain by altering the behavior of nearby cells called microglia.
You know that feeling in your gut? We think of it as an innate intuition that sparks deep in the belly and helps guide our actions, if we let it. It's also a metaphor for what scientists call the 'gut-brain axis,' a biological reality in which the gut and its microbial inhabitants send signals to the brain, and vice versa.
A new study in Neuron offers clues to why autism spectrum disorder (ASD) is more common in boys than in girls. National Institutes of Health scientists found that a single amino acid change in the NLGN4 gene, which has been linked to autism symptoms, may drive this difference in some cases. The study was conducted at NIH's National Institute of Neurological Disorders and Stroke (NINDS).
Stroke survivors who engage in a lot of light physical activity -- taking leisurely walks or attending to nonstrenuous household chores, for example -- also report fewer physical limitations than their more sedentary peers, a new study finds.
The face of a mouse reveals its emotions.
Researchers from King's College London have shown that how we respond to changes in nutrients at a molecular level plays an important role in the aging process, and this is directed by some key genetic mechanisms.
Using a machine learning algorithm to analyze mouse facial expressions, Nejc Dolensek and colleagues have uncovered the neurological origins of emotional states.
Before they were banned about a half century ago, psychedelic drugs like LSD and psilocybin showed promise for treating conditions including alcoholism and some psychiatric disorders. In a commentary publishing April 2 in the journal Cell, researchers say it's time for regulators, scientists, and the public to 'revisit drugs that were once used but fell out of use because of political machinations, especially the war on drugs.'
Cold brew may be the hottest trend in coffee-making, but not much is known about how this process alters the chemical characteristics of the beverage. Now, scientists report that the content of potentially health-promoting antioxidants in coffee brewed without heat can differ significantly from a cup of joe prepared the traditional way, particularly for dark roasts.
