| New algorithm could help enable next-generation deep brain stimulation devices Posted: 01 Jun 2021 01:50 PM PDT Researchers have developed a technique that could allow deep brain stimulation devices to sense activity in the brain and adjust stimulation accordingly. |
| Modulating rapamycin target protein promotes autophagy, lowering toxic Huntingtin protein Posted: 01 Jun 2021 01:50 PM PDT Recent failed clinical trials of a drug designed to clear the mutant Huntingtin protein that causes Huntington's disease (HD) heightens the need for new approaches for the devastating, incurable, progressive neurodegenerative genetic disorder. Scientists have found that the targeting the protein called FK506-binding protein 51 or FKBP51 promotes the clearing of those toxic proteins via autophagy, a natural process whereby cells recycle damaged proteins and mitochondria and use them for nutrition. |
| Role of sleep-related brain activity in clearing toxic proteins and preventing Alzheimer's disease Posted: 01 Jun 2021 12:20 PM PDT Evidence of sleep-dependent low-frequency (less than 0.1 Hz) global brain activity in the clearance of Alzheimer's disease-related toxin buildup is presented in new research. This neuronal activity was more strongly linked with cerebrospinal fluid flow in healthy controls than higher risk groups and patients, and the findings could serve as a potential imaging marker for clinicians in evaluating patients. |
| Healthy lifestyle linked to better cognition for oldest adults -- regardless of genetic risk Posted: 01 Jun 2021 12:20 PM PDT A new analysis of adults aged 80 years and older shows that a healthier lifestyle is associated with a lower risk of cognitive impairment, and that this link does not depend on whether a person carries a particular form of the gene APOE. |
| Improved detection of atrial fibrillation could prevent disabling strokes Posted: 01 Jun 2021 12:20 PM PDT A clinical trial examining the efficacy of two devices to monitor and detect atrial fibrillation (AF), or an irregular heartbeat, in ischemic stroke patients -- one an implantable device that monitors over 12 months, the other an external device that monitors over a 30-day period -- found the implantable device is more than three times more effective in detecting AF. |
| Scientists identify mechanism linking traumatic brain injury to neurodegenerative disease Posted: 01 Jun 2021 10:58 AM PDT Scientists have revealed a potential mechanism for how traumatic brain injury leads to neurodegenerative diseases. |
| Junk food game helps people eat less and lose weight Posted: 01 Jun 2021 10:58 AM PDT Using a brain-training app helps people eat less junk food and lose weight, new research suggests. |
| How news coverage affects public trust in science Posted: 01 Jun 2021 10:57 AM PDT News media reports about scientific failures that do not recognize the self-correcting nature of science can damage public perceptions of trust and confidence in scientific work, according to new findings. |
| Early bird or night owl? Study links shift worker sleep to 'chronotype' Posted: 01 Jun 2021 10:57 AM PDT Getting enough sleep can be a real challenge for shift workers affecting their overall health. But what role does being an early bird or night owl play in getting good rest? Researchers find a link between chronotype and amount of sleep shift workers can get with their irregular schedules. |
| Head injury and concussion in toddlers: Early detection of symptoms is vital Posted: 01 Jun 2021 09:18 AM PDT Concussions can have serious consequences for toddlers. A research team has developed a tool to detect them in children who do not yet speak or have a limited vocabulary. |
| Protecting the intellectual abilities of people at risk for psychosis Posted: 01 Jun 2021 09:17 AM PDT Psychotic disorders comes with a progressive decline in IQ. If current drug treatments are successful in containing psychotic symptoms, nothing can be done to prevent the deterioration of intellectual skills that leads to loss of autonomy. Researchers have discovered that prescription of selective serotonin reuptake inhibitors (SSRIs) in late childhood can reduce the deterioration of intellectual abilities and have a neuroprotective effect on some of the brain regions affected by the psychotic illness. |
| ALS development could be triggered by loss of network connections in the spinal cord Posted: 01 Jun 2021 09:17 AM PDT The network connection between nerve cells in the spinal cord seems to play a critical role in the development of the severe disease ALS, a new study suggests. The study, which is based on a mouse model, may change the way we think about the disease, says researchers. |
| Scientists say active early learning shapes the adult brain Posted: 01 Jun 2021 07:07 AM PDT Through the Abecedarian Project, an early education, randomized controlled trial that has followed children since 1971, researchers have discovered an enhanced learning environment during the first five years of life shapes the brain in ways that are apparent four decades later. |
| Posted: 01 Jun 2021 07:07 AM PDT The average IQ of adults who were born very preterm (VP) or at a very low birth weight (VLBW) has been compared to adults born full term. Researchers have found VP/VLBW children may require special support in their education to boost their learning throughout childhood. |
| Memory, learning and decision-making studied in worms Posted: 01 Jun 2021 07:06 AM PDT As anyone who has ever procrastinated knows, remembering that you need to do something and acting on that knowledge are two different things. To understand how memory can lead to different behaviors, researchers studied the simpler nervous system of worms. The discovery used a 'robot microscope,' which detects and tracks fluorescent light as a worm crawls around, meaning researchers can record videos of chemical signals traveling between individual neurons in awake, unrestrained animals. |
| Overconfidence in news judgement and false news susceptibility Posted: 31 May 2021 12:32 PM PDT Individuals who falsely believe they are able to identify false news are more likely to fall victim to it. |
