Neuroscientists show how common parasitic infection causes seizures and psychiatric illness for some
Forty million Americans are infected with a parasite called Toxoplasma gondii. For most patients, the infection is mild, while others develop seizures or psychiatric disorders. A new study led by Michael Fox at the Fralin Biomedical Research Institute describes how brain circuits change as the parasite finds long-term shelter inside brain cells. The study’s first author and doctoral candidate, Gabriela Carrillo, explains this discovery.
Scientists discover cellular structure of poorly understood visual brain region
The brain’s ventral lateral geniculate nucleus (vLGN) receives signals from the eye, but it is not associated with classical image-forming. For decades little was known about this brain region’s cellular structure and purpose. In a new study published in the Journal of Neurochemistry, Fralin Biomedical Research Institute neuroscientists reveal newly identified brain cell subtypes unique to this region that form a striking layered formation.
About the Center for Neurobiology Research
Fralin Biomedical Research Institute scientists in this center investigate the cellular and molecular mechanisms underlying brain development to understand how these cells are altered by genetic variations, neurodegenerative disorders, trauma, and aging. Discoveries made by these laboratories are helping explain the origins of a wide range of brain diseases, while also searching for new approaches to diagnosis and treatment.

Researchers from the Virginia Tech Carilion Research Institute recently got a surprise after performing what they assumed to be a routine experiment in neurodevelopment. It was thought that taking away the receptors for an important glycoprotein called Reelin would hinder a developing brain the same way as taking away Reelin itself. The results, however, revealed major differences, indicating that both Reelin and its receptors have more roles than anyone knew.
