Your brain is your most powerful sex organ. Here's why.
Researchers attempt to distill the science of dirty talk, submissive sexual activity, and the overall nature of arousal.
When we think of sex organs, our minds veer toward the naughty parts between our legs. But our minds should be veering to, well, our minds. The real catalyst for sexual activity is the brain — specific parts of the brain — not genitalia. That's why sexually driven language — dirty talk — is so arousing. When partners talk dirty to each other, they're stroking the right organs.
A wealth of scientific research establishes the brain's primary role in sexual activity. Sex drive, for example, originates in the hypothalamus, which is responsible for testosterone production in the testes. The amygdala, on the other hand, is a center for fear in the brain. Both brain regions strongly effect how we respond to dirty talk and sexual stimulation in general.
Because men have larger hypothalami, for instance, they have more testosterone. This explains why the male sex drive often exceeds those of females, why men tend to initiate sexual contact, and why men are less cautious about who they take on as sexual partners. Partners who seek a submissive role, on the other hand, are led more by their amygdala, one of the brain's fear centers.
Dirty talk achieves arousal because it's fine-tuned to stimulate the right parts of the brain. It feeds our need for intimate conversation and lust for sexual activity. It provides a multi-layered sexual experience that extends further than just physical touch. Dirty talk works because it's sex through suggestion, and to our brains, suggestion can be just as powerful as full-on execution.
Universities claim to prepare students for the world. How many actually do it?
- Many university mission statements do not live up to their promise, writes Ben Nelson, founder of Minerva, a university designed to develop intellect over content memorization.
- The core competencies that students need for success—critical thinking, communication, problem solving, and cross-cultural understanding, for example—should be intentionally taught, not left to chance.
- These competencies can be summed up with one word: wisdom. True wisdom is the ability to apply one's knowledge appropriately when faced with novel situations.
This is what the world will look like, 250 million years from now
To us humans, the shape and location of oceans and continents seems fixed. But that's only because our lives are so short.
A new study may help us better understand how children build social cognition through caregiver interaction.
Researchers at UT Southwestern noted a 47 percent increase in blood flow to regions associated with memory.
- Researchers at UT Southwestern observed a stark improvement in memory after cardiovascular exercise.
- The year-long study included 30 seniors who all had some form of memory impairment.
- The group of seniors that only stretched for a year did not fair as well in memory tests.
