Brain Physiology of Love and Sex

Elizabeth Cohen posted this story on CNN about what cognitive scientists are learning about love.We exchanged a few emails on the subject so I figured I'd take one of them and post this blog entry.

Cohen wrote, “In a group of experiments, Dr. Lucy Brown, a professor in the department of neurology and neuroscience at the Albert Einstein College of Medicine in New York, and her colleagues did MRI brain scans on college students who were in the throes of new love.  While being scanned, the students looked at a photo of their beloved. The scientists found that the caudate area of the brain -- which is involved in cravings -- became very active. Another area that lit up: the ventral tegmental, which produces dopamine, a powerful neurotransmitter that affects pleasure and motivation."

What is a Mammal?

I just heard a piece by Nell Boyce on NPR.  It was great radio and mostly good science. But it wasn’t very good History.  I definitely learned more about mammals.  I was intrigued with the story of the word itself, so interested, in fact, that I listened to the story several times and conducted my own research.  But ultimately, I learned more about how the preeminent naturalist of the 17th Century fails to measure up to 21st Century standards of political correctness than I learned about what science was really like back then or what it is like today.  And in so doing, it probably deceives the reader about what the process of Science is really like more than it enlightens.
