An evolutionary ancient brain region drives modern-day cognition

The superior colliculus is a midbrain region that is traditionally thought to help animals orient themselves toward important locations in space, like directing their eyes and head toward a bright flash of light. New research from the University of Chicago shows that this part of the brain also plays a role in complex cognitive tasks like visual categorization and decision making.

New insights into the mechanisms of efavirenz-induced neurotoxicity

Efavirenz is an important drug for treating HIV infection, but it has negative effects that can significantly impact patients' quality of life over time. It causes neuropsychiatric disorders and neurocognitive impairment in roughly 50 percent of patients. The drug is associated with abnormal lipid levels in blood plasma, but the molecular mechanisms responsible for negative clinical observations are unknown.
