MDMA Makes People More Cooperative, But Not GullibleNews
New research from King’s College London has found that MDMA, the main ingredient in ecstasy, causes people to cooperate better - but only with trustworthy people. In the first study to look in detail at how MDMA impacts cooperative behaviour the researchers also identified changes to activity in brain regions linked to social processing.
Autism Gene Makes Mouse Brains Less FlexibleNews
About 1% of patients diagnosed with autism spectrum disorder and intellectual disability have a mutation in a gene called SETD5. Scientists have now discovered what happens on a molecular level when the gene is mutated in mice, and how this changes the mice’s behavior.READ MORE
The Cerebellum Makes Moves and MemoriesNews
The cerebellum, a structure found in the back of the skull, is known to be important for the control of movement, while the frontal cortex is responsible for cognitive functions such as short-term memory and decision making. However, as researchers continue to unlock the mystery of how billions of neurons in the brain interact, it is becoming more apparent that it is not that black and white.
The tissues in our bodies largely are made of fluid. It moves around cells and is essential to normal body function. In people who have glioblastoma, the deadliest form of brain cancer, this fluid has a much higher pressure, causing it to move fast and forcing cancer cells to spread. Researchers may have found a solution to stopping this inevitable cancer cell spread.READ MORE
Single-cell transcriptomics revealed 10-20% of cells in a kidney organoid were non-renal cells.READ MORE
Restoring the ability to walk following spinal cord injury requires neurons in the brain to reestablish communication pathways with neurons in the spinal cord, Mature neurons, however, are unable to regenerate their axons to facilitate this process. New research in mice shows one potential route to overcome this limitation may be by targeting liver kinase B1 (LKB1) protein.
From online forums to community groups, research and experience shows people are more willing to insult and use menacing language online than in person, especially when there’s the protection of anonymity behind a computer. New research indicates that people react less strongly to malicious speech on digital platforms and see the victims as less “harmed” than if the words were said directly to a person.
The number of young adults living in their own household has dropped dramatically in the last decades in the United States, and a growing proportion of young people will move back in with their parents at some point in time. These “boomerang” moves are associated with an increase in depressive symptoms, a recent MPIDR study suggests.
Doctors may one day be able to gauge a patient's risk of dementia with an MRI scan. Using a new technique for analyzing MRI data, researchers were able to predict who would experience cognitive decline with 89 percent accuracy.READ MORE
UCLA biologists have discovered how head injuries adversely affect individual cells and genes that can lead to serious brain disorders, proposing gene candidates to treat brain diseases associated with traumatic brain injury, such as Alzheimer’s disease and post-traumatic stress disorder.
Researchers using a new type of magnetic resonance imaging to take brain scans of teenage football players suggest that just one season of playing might be enough to cause microscopic changes in the structure of the brain, even whilst wearing helmets and not sustaining concussions.READ MORE
Exposure to uncomfortable sensations elicits a wide range of appropriate and quick reactions, from reflexive withdrawal to more complex feelings and behaviors. To better understand the body’s innate response to harmful activity, researchers at the National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health, have identified activity in the brain that governs these reactions.READ MORE
