Study Uncovers Blood Vessel Damage & Inflammation in COVID-19 Patients’ Brains but No Infection

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.

Why Some Words May Be More Memorable than Others

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.

Scientists monitored brains replaying memories in real time

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.

‘Sticky’ gene may help Valium calm nerves

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.

The brain may actively forget during dream sleep

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.

Smoldering spots in the brain may signal severe MS

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.
