A new study published by Penn Medicine researchers this month and featured on the cover of the Journal of Neuroscience may help resolve this puzzle, revealing that while volume indeed decreases from childhood to young adulthood, gray matter density actually increases.
UC San Diego study of US data suggests a sleep-deprived planet by century's end. Researchers show that unusually warm nights can harm human sleep and that the poor and elderly are most affected. Rising temperatures will make sleep loss more severe.
Stroke patients who learned to use their minds to open and close a plastic brace fitted over their paralyzed hands gained some ability to control their own hands when they were not wearing the brace, according to a new study from Washington University School of Medicine in St. Louis. The participants, all of whom had moderate to severe paralysis, showed significant improvement in grasping objects.
In a small, randomized Phase I/II clinical trial (SAT1), researchers at University of California San Diego School of Medicine say a 100-year-old drug called suramin, originally developed to treat African sleeping sickness, was safely administered to children with autism spectrum disorder (ASD), who subsequently displayed measurable, but transient, improvement in core symptoms of autism.
Research published in the Journal of Clinical Investigation Insight shows that cellular stress in the brain may contribute to development of nonalcoholic fatty liver disease.
The research findings imply that patients with genitourinary birth defects due to 22q11.2 changes in gene dosage should also be evaluated for other potential birth defects seen in patients with DiGeorge syndrome that would affect the patient's future health.
A new study has uncovered a molecular mechanism in the prion protein, a protein responsible for neurodegenerative diseases, which may explain why nerve cells degenerate in these disorders. The findings, which appear in the journal eLife, may one day lead to better therapies and treatments for these diseases
What happens in the brain when we see other people experiencing a trauma or being subjected to pain? Well, the same regions that are involved when we feel pain ourselves are also activated when we observe other people who appear to be going through some painful experience. This is shown in a study from Karolinska Institutet in Sweden published in Nature Communications.
In a new study, published this week in Current Biology, a team of University of Pennsylvania researchers report newly mapped changes in the network organization of the brain that underlie those improvements in executive function. The findings could provide clues about risks for certain mental illnesses.
The human brain functions on a delicate balance of reinforcing positive behaviors and suppressing negative ones, which takes place in the dorsal striatum, a brain region critical for goal-directed behavior and implicated in drug and alcohol addiction.
