" In my book, Memoirs of an Addicted Brain, I weave together a personal account of my years of addiction with descriptions of brain states induced by drugs ranging from alcohol and LSD to heroin, as well as brain states underlying addiction itself.
Why are addicts so desperate? Why is it so hard to stop? Neuroscientists seek the answer in a single molecule: dopamine—a neuromodulator long associated with reward." (Book)
