| Magnetic field from MRI affects focused-ultrasound-mediated blood-brain barrier Posted: 12 Jul 2021 12:03 PM PDT Researchers have found that the magnetic field of the MRI scanner decreased the BBB opening volume by 3.3-fold to 11.7-fold, depending on the strength of the magnetic field, in a mouse model. |
| A redundant modular network supports proper brain communication Posted: 12 Jul 2021 10:01 AM PDT In a mouse model, brain regions involved in working memory present a modular network organization that is critical for persistent neural activity. |
| Technology that restores the sense of touch in nerves damaged as a result of injury Posted: 12 Jul 2021 09:21 AM PDT Researchers have developed a sensor that can be implanted anywhere in the body -- for example, under the tip of a severed finger. The sensor connects to another nerve that functions properly and restores tactile sensation to the injured nerve. The development is biocompatible and does not require electricity, wires, or batteries. |
| Preferred life expectancy and its association with hypothetical adverse life scenarios Posted: 12 Jul 2021 09:21 AM PDT A new study sheds light on how the specter of dementia and chronic pain reduce people's desire to live into older ages. Among Norwegians 60 years of age and older the desire to live into advanced ages was significantly reduced by hypothetical adverse life scenarios with the strongest effect caused by dementia and chronic pain. |
| People given 'friendly' bacteria in nose drops protected against meningitis, study suggests Posted: 12 Jul 2021 09:21 AM PDT A recent trial has shown that nose drops of modified 'friendly' bacteria may protect against meningitis. |
| Training helps teachers anticipate how students with learning disabilities might solve problems Posted: 12 Jul 2021 09:20 AM PDT Researchers found that a four-week training course made a substantial difference in helping special education teachers anticipate different ways students with learning disabilities might solve math problems. |
| A step toward advancing precision hormone therapies to reduce Alzheimer's risk Posted: 12 Jul 2021 06:22 AM PDT When it comes to post-menopausal hormone therapy, the type, route and duration all play a role in reducing the risk of neurodegenerative diseases. |
| Innovative gene therapy 'reprograms' cells to reverse neurological deficiencies Posted: 12 Jul 2021 06:22 AM PDT A novel method of gene therapy is helping children born with a rare genetic disorder called AADC deficiency that causes severe physical and developmental disabilities. The study offers new hope to those living with incurable genetic and neurodegenerative diseases. |
| A Trojan horse could help get drugs past our brain's tough border patrol Posted: 12 Jul 2021 06:22 AM PDT The blood-brain barrier protects the brain and is notoriously hard to get past for drug delivery, making it difficult to treat disorders in the central nervous system. In a mice study, a team of researchers used a novel approach to study the barrier and in detail characterized a Trojan horse technique to help to solve the challenge. |
