Article- Serotonin and the science of sex
In 2011, a group of scientists “turned mice gay.” The only issue is, of course, they didn’t.
Rather, Yi Rao and colleagues at Peking University in Beijing, China, showed that male mice will cheerfully mount both male and female mice, as long as their brains are deficient in one chemical messenger: serotonin. The paper, published in Nature, received plenty of media coverage. Now, two other research groups report seemingly opposite findings: Male mice with no serotonin in their brains still prefer female mice to males. The researchers contend that serotonin is about social communication and impulsive behaviors, not sex.

And it’s about what, exactly, those behaviors really mean. - Read More (Source - Science News, Images- Kuttelvaserova Stuchelova)
