Cocaine and the teen brain: New insights into addiction:
'via Blog this'
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.
The findings may help explain why risk of drug abuse and addiction increase so dramatically when cocaine use begins during teenage years.
The results were published in the Feb. 14 and Feb. 21 issues of the Journal of Neuroscience.
