Scientists have identified a biological explanation for Long COVID brain fog, revealing a potential path toward diagnosis and treatment. Credit: Stock Researchers employed a specialized brain imaging technique to identify a potential biomarker and therapeutic target for Long COVID. More than four years after the onset of the COVID-19 pandemic, scientists are still working to fully understand the lingering effects …

Autofluorescence suppression and high-sensitivity microscopy reveals nanoscale assemblies in human brain tissue An overview of the ASA–PD pipeline is shown in Fig. 1. In brief, the aim is to capture spatial data over the entire scale of structure sizes most critical in PD, from individual cells to small aggregates (Fig. 1a). Detailed descriptions of the sample preparation steps are described …

Antonia Matthews and Danielle HerbertBBC Wales Corinne Wardle Molly had nine hours of surgery, aged just 12 weeks, when the tumour was finally discovered A mum whose baby daughter was diagnosed with a brain tumour, after her symptoms were dismissed as colic and reflux for more than two months, is calling for better awareness of the condition. Newborn Molly appeared …

Low-normal B12 in older adults was tied to slower processing, cognitive decline, and brain damage. Scientists warn that current requirements may be too low. Credit: SciTechDaily.com Even “normal” levels of vitamin B12 may not be enough to protect the aging brain. UCSF researchers found that older adults with lower, but still technically normal, B12 showed slower processing speeds, more white …

Manifesting isn’t all “woo-woo.” Science says you can train your brain  Axios Source link

A French and Canadian team used a molecular switch to boost energy production from mitochondria inside brain cells, restoring memory in mice with dementia-like symptoms. The work links energy failure in neurons to cognitive problems and points to a new target for therapy, as shown in a recent study. The brain burns through fuel quickly, and trouble starts …

Inhibitory neurons have “often been ascribed support roles,” said Annabelle Singer, a neuroscientist and neuroengineer at the Georgia Institute of Technology and Emory University. That’s likely because it’s simply easier to study excitatory neurons. For example, an excitatory place cell in the hippocampus can fire when an animal is in a particular location. When this happens, its excitation of other …

What gives rise to human consciousness? Are some parts of the brain more important than others? Scientists began tackling these questions in more depth about 35 years ago. Researchers have made progress, but the mystery of consciousness remains very much alive. In a recently published article, I reviewed over 100 years of neuroscience research to see if some brain regions …
