If anyone has an interest in how drugs (medicinal, recreational, etc) work in the brain to produce their various effects, Coursera is offering an excellent 7 week FREE Cal Tech course starting Jan 4. For full info click the link. Coursera - Drugs and the Brain PM me if you want the textbook (pdf) for free. Here's the course description: It's a good one! But there all good at Coursera and EDX. Btw - don't let the "Requirements" section or the textbook scare you away. The only REAL requirements are curiosity and a little ambition. If you choose, you can just watch the lecture videos (won't be available at YouTube) and play with the textbook. Cheers!
