Cocaine and the teen brain: Study offers insights into addiction
When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug’s effects, Yale and other scientists have found. Now two new studies by a Yale team identify key genes that regulate this response and show that interfering with this reaction dramatically increases a mouse’s sensitivity to cocaine.
A mechanism to improve learning and memory
There are a number of drugs and experimental conditions that can block cognitive function and impair learning and memory. However, scientists have recently shown that some drugs can actually improve cognitive function, which may have implications for our understanding of cognitive disorders such as Alzheimer’s disease. The new research is reported 21 February in the open-access journal PLoS Biology.
Being born in another country may protect against stroke for US Hispanics
