| Toward next-generation brain-computer interface systems Posted: 12 Aug 2021 10:59 AM PDT A new kind of neural interface system that coordinates the activity of hundreds of tiny brain sensors could one day deepen understanding of the brain and lead to new medical therapies. |
| Scrap the nap: Study shows short naps don’t relieve sleep deprivation Posted: 12 Aug 2021 09:31 AM PDT The latest study shows that short naps are ineffective in mitigating the potentially dangerous cognitive effects of sleep deprivation. |
| From blood to brain: Delivering nucleic acid therapy to the CNS Posted: 12 Aug 2021 09:31 AM PDT Researchers have developed a drug delivery platform wherein heteroduplex oligonucleotide drugs conjugated with cholesterol are able to cross the blood-brain barrier and achieve therapeutic concentrations in the central nervous system even with intravenous or subcutaneous dosing. The ability to target gene expression in the central nervous system through systemically administered nucleic acid therapy holds great promise for the treatment of neurogenerative disease. |
| Discovery raises possibility of new medication for Alzheimer’s, Parkinson’s Posted: 12 Aug 2021 06:27 AM PDT Researchers have for the first time demonstrated it's possible to use a synthetic thyroid hormone to regulate a gene implicated in neurodegenerative diseases like Alzheimer's, Parkinson's and multiple sclerosis. |
| Posted: 12 Aug 2021 06:27 AM PDT A new study suggests that skin fibroblasts from frontotemporal dementia patients may be useful in investigating underlying disease mechanisms as well as in biomarker and drug research. |
| Lyme disease heightens risk of mental disorders, suicidality Posted: 11 Aug 2021 08:31 AM PDT A new study reports that patients hospitalized with Lyme disease had a 28 percent higher rate of mental disorders and were twice as likely to attempt suicide. Physicians and patients should be aware of the potential for psychiatric symptoms post-Lyme infection, particularly during the first year after diagnosis. |
| Study of skull birth defect takes it from the top Posted: 11 Aug 2021 08:31 AM PDT A new study presents a detailed cellular atlas of the developing coronal suture, the one most commonly fused as a consequence of single gene mutations, leading to birth defects such as craniosynostosis. With an aim toward advancing new interventions for patients, researchers created the first detailed cell-by-cell description of how this suture develops. They identified 14 distinct types of cells in and around the developing suture and new genes that may be involved in generating and maintaining the stem cells that grow the skull bones on either side of the suture. |
| Deep learning model classifies brain tumors with single MRI scan Posted: 11 Aug 2021 07:08 AM PDT A team of researchers have developed a deep learning model that is capable of classifying a brain tumor as one of six common types using a single 3D MRI scan, according to a new study. |
| Posted: 11 Aug 2021 06:16 AM PDT Those youngest in a class were more likely to experience low educational achievement, substance misuse disorder, and depression in later life. However, younger children with ADHD appeared less at risk of depression. |
| New technique identifies proteins in the living brain Posted: 11 Aug 2021 06:15 AM PDT In the new study, researchers designed a virus to send an enzyme to a precise location in the brain of a living mouse. Derived from soybeans, the enzyme genetically tags its neighboring proteins in a predetermined location. After validating the technique by imaging the brain with fluorescence and electron microscopy, the researchers found their technique took a snapshot of the entire set of proteins (or proteome) inside living neurons, which can then be analyzed postmortem with mass spectroscopy. |
| How hormones may alleviate side-specific movement difficulties after brain injury Posted: 10 Aug 2021 07:46 AM PDT Hormones released after a brain injury contribute to movement problems on the left and right sides of the body, scientists from Uppsala University and elsewhere can now show in a new study in rats. The results also suggest that hormone-blocking treatments may help counteract these effects, a finding that has implications for treating people with traumatic brain injuries or stroke. |
