I recently met a guy with a sexual secret. He was 39, in great shape, and in his spare time was a CrossFit athlete. But he had diabetes, and he told me that it made him impotent. Besides, an erect, on-demand, rock hard schlong that could go for hours? I was in. And now that women are getting vaginal rejuvenation to tighten their baby makers, it seemed silly to be afraid of the latest improvements in medical technology.
Neurons derived from two different types of precursor cells that later develop into neurons in the medial amygdala -- one of the interconnected structures in the brain involved in emotion, motivation and memory -- help to program innate reproductive and aggressive behaviors into the brain, research led by Children's National Health System indicates. The finding, published April 7, in the journal eLife , helps to explain how events that occur when the fetal brain is developing may program instinctual behaviors relied on by creatures big and small, such as avoiding predators, mating and protecting their territory. One precursor cell type expresses a developmentally regulated transcription factor, a protein known as Dbx1; the other cell type expresses Foxp2, the forkhead transcription factor previously identified in humans as required for appropriate production of speech. When cells derived from these distinct cell subpopulations are activated during certain encounters, they show differing patterns of activation in male, versus female brains. Corbin, Ph. What's most surprising is the same population of neurons exists in the male brain as the female brain, yet they respond differently to mating cues," Corbin adds.
Stretching is a form of physical exercise in which a specific muscle or tendon or muscle group is deliberately flexed or stretched in order to improve the muscle's felt elasticity and achieve comfortable muscle tone. Stretching is also used therapeutically to alleviate cramps and to improve function in daily activities by increasing range of motion. In its most basic form, stretching is a natural and instinctive activity; it is performed by humans and many other animals.
