Immune cells sculpt circuits in the brain

Immune cells play an unexpected role in fine-tuning the brain’s neural circuits, according to research published in September, 2020 in Neuron. The immune cells that reside there, known as microglia, not only protect the brain from infection and inflammation, they also help physically sculpt circuits in the developing brain. The…

Autism researchers map brain circuitry of social preference

Some individuals love meeting new people, while others abhor the idea. For individuals with conditions such as autism, unfamiliar social interactions can produce negative emotions such as fear and anxiety. A new study from Scripps Research reveals how two key neural circuits dictate the choice between social approach and avoidance….

Multi-institutional study looks at brain MRI findings in COVID-19

A new multi-institutional study published in the journal Radiology identifies patterns in abnormal brain MRI findings in patients with COVID-19. Current data on central nervous system (CNS) involvement in COVID-19 is uncommon but growing, demonstrating a high frequency of neurological symptoms. However, the delineation of a large cohort of confirmed…
