Researchers found hallmarks of damage caused by thinning and leaky blood vessels in brain samples of people after contracting COVID-19, but saw no evidence of SARS_CoV_2 in the tissue samples. Findings suggest the damage was not caused by a direct viral attack on the brain, but by the body's immune response to the infection.
The adult nervous system of a C. elegans worm contains 302 neurons, which can be divided into 118 types. Seventy homeobox genes are involved in characterizing the neuron types.
Experimental drugs designed to reduce the body's natural production of alpha-ketoglutarate slow tumor growth and increase lifespan in mouse models of DIPG.
Deactivation of the HERV-K gene may free stem cells to become neurons.
Some words are far more memorable than others. Researchers discovered our memories are wired into neural networks that allow the brain to search for these memories, much like the way search engines track down relevant information.
Microglia help limit infection to the olfactory bulb and protects neurons from damage that could occur as a result of viral infection.
SCAPE microscopy, a new 3D imaging technique, allows a greater volume of brain tissue to be viewed in a much less damaging way to networks of living cells.
Firing patterns of neurons that occurred following a word-learning task are replayed fractions of a second later, before recalling the words. Findings suggest the brain uses distinct firing patterns to store and replay memories.
Enhancing mitochondrial transportation and cellular energetics could help promote regeneration and function following spinal cord injury.
A new study challenges existing theories about how benzodiazepines, such as valium, work to calm nerves. Researchers report a 'sticky' gene called Shisa7 plays a critical role in the regulation of inhibitory neural circuits, and the sedative effects benzodiazepines have on circuit activity.
REM sleep has previously been linked to memory formation. A new study reveals this sleep period may also be critical for us to forget certain memories, preventing information overload. Researchers identified a mechanism involving MCH neurons which causes us to forget information during sleep.
Dark rimmed spots on the brain that represent ongoing inflammation, known as chronic active lesions, may be a hallmark of a more aggressive and debilitating form of multiple sclerosis. The findings provide a new biomarker for diagnosing the neurological disorder.
