A new computational model uses the entire function of the brain rather than specific networks or areas to explain the relationship between mental processing and brain anatomy. The model aims to discover how the brain works and breaks down as a result of aging and dementia.
Researchers explore the close relationship between depression and pain. For some people, unexplained symptoms of pain, such as back or headaches, could be an early indicator of depression before mood changes occur.
A global knockout of the thrombin receptor PAR1 accelerates myelin development. The findings could help with the development of treatments for diseases associated with demyelination, like multiple sclerosis.
Researchers report senescent, or Zombie, cells accumulate in certain neurons prior to cognitive loss. By preventing accumulation of these cells, researchers were able to diminish apoptosis, memory loss and tau aggregation.
The sensitivity of current RT-PCR testing for COVID-19 and overall test performance characteristics have not been reported clearly or consistently in medical literature. Researchers say doctors should expect a less visible second wave of coronavirus infections from people with false-negative test results.
