Dementia risk increased in 50-year-olds with blood pressure below hypertension threshold

Posted: 12 Jun 2018 05:18 PM PDT

New findings from the long-running Whitehall II study of over 10,000 civil servants has found 50-year-olds who had blood pressure that was higher than normal but still below the threshold commonly used when deciding to treat the condition, were at increased risk of developing dementia in later life. This increased risk was seen even when the study participants did not have other heart or blood vessel-related problems, according to the research.

Psychedelic drugs promote neural plasticity in rats and flies

Posted: 12 Jun 2018 03:52 PM PDT

Psychedelic drugs may have mind-altering powers in the physical sense, too. A new study has found psychedelics, specifically DOI, DMT, and LSD, can change brain cells in rats and flies, making neurons more likely to branch out and connect with one another. The work supports the theory that psychedelics could help to fight depression, anxiety, addiction, and post-traumatic stress disorder.

People who deeply grasp pain or happiness of others, process music differently in brain

Posted: 12 Jun 2018 03:51 PM PDT

People who deeply grasp the pain or happiness of others also process music differently, say researchers. The study in Frontiers in Behavioral Neuroscience compared MRI scans of low- and high-empathy people. Higher empathy people process music like a pleasurable proxy for a human encounter -- in brain regions for reward and social awareness. The findings may have implications for the function of music now and in our evolutionary past.

Beyond the 'Reading Wars': How the science of reading can improve literacy

Discovery shines light on the mystery of cell death in MS

Posted: 12 Jun 2018 03:50 PM PDT

Researchers have discovered a unique process of brain cell death that affects the cells that are most vulnerable in multiple sclerosis (MS). After identifying the process called pyroptosis, or fiery death, the researchers were able to block the enzyme in the brain that is responsible for it, using a drug that could potentially treat MS.

Graphene carpets: So neurons communicate better

Posted: 12 Jun 2018 07:57 AM PDT

Scientists have experimentally observed the phenomenon of ion 'trapping' by graphene carpets and its effect on the communication between neurons. The researchers have observed an increase in the activity of nerve cells grown on a single layer of graphene. Combining theoretical and experimental approaches they have shown that the phenomenon is due to the ability of the material to 'trap' several ions present in the surrounding environment on its surface, modulating its composition.
