Researchers identified an abnormal link between the autonomic and central nervous system via communication between the heart and parts of the prefrontal cortex in women with generalized anxiety disorder.
Immune cells in the meninges monitor fluid released from the brain. If the fluid contains signs of infection, disease, or damage, the immune cells initiate an immune response to tackle the problem.
Mice exposed to COVID-19 through the nasal passage, researchers noted a rapid and escalated attack on the brain by the virus that triggered a more severe outcome of the infection, even after the lungs were cleared of the disease. Researchers also found virus levels were over 1,000 times higher in the brain than other parts of the body.
Study looks at the evolutionary development of the human brain.
A new deep learning system is able to predict, with great accuracy, how different brain areas respond to specific words. The model also found concepts localized to the auditory cortex are less dependent on context.
