once promised an anesthesiologist that if he successfully brought her through
surgery, then, and only then, would she reveal to him the secret of male
professor emerita of Rutgers’ College of Nursing delivered – well, that’s
between her and her anesthesiologist. But for anyone who is interested in the
subject of orgasm – and who isn’t? – what Whipple and Barry Komisaruk, a neuropsychologist at
Rutgers–Newark, share in their new book, The
Science of Orgasm (Johns Hopkins, 2006), is nothing less than a
comprehensive survey of everything scientists know about the complex biological
processes leading to orgasm.
Much of that
knowledge comes from the pair’s own 25-year research collaboration. Whipple, a
registered nurse and sex educator who, in 2006, was named one of the world’s 50
most influential scientists by New
Scientist magazine, studies women’s sexuality, while Komisaruk, who is a
Rutgers Board of Governors Distinguished Service Professor, focuses on the
sensory pathways of pain and pleasure.
“We realized from the first day we met
that our research matched perfectly,” says Whipple, the pioneering sex
researcher who helped name the G spot, affirmed the phenomenon of female
ejaculation, and proved that women can climax through fantasy alone.
Whipple and Komisaruk have documented the pain-blocking effects of vaginal
stimulation; mapped the specific brain areas that are activated during orgasm;
and identified a route through which women with complete spinal cord injury can
reach orgasm – the vagus nerve, which bypasses the spine to directly connect
the genitalia and the brain. Using advanced brain-imaging techniques, the pair
has shown that even nongenital stimulation can activate the orgasmic regions of
the brain, potentially validating the experiences of people who claim to climax
in dreams or through stimulation of the neck, breast, mouth – even the knee and
the big toe.
“Orgasm isn’t just a muscular reflex,” asserts Whipple, “it’s a
perception of the brain.”
So is pain – and,
ironically, both pain and pleasure register in the same areas of the brain, as
Whipple and Komisaruk have shown in the brain scans of volunteers. Pain and
pleasure, those strange bedfellows of the brain, have a rather close
relationship. “Think of the facial expressions of orgasm,” suggests Komisaruk.
“People take on the appearance of agony – almost like virtual pain – during
orgasm.” In fact, their brain-imaging studies show that women can withstand up
to 100 percent more pain during an orgasm; in essence, the brain pushes out the
pain to make way for the pleasure.
The ability to
monitor brain activity in real time – as Whipple and Komisaruk do with a
sophisticated brain-imaging technique called functional MRI (fMRI) – raises the
intriguing possibility of teaching people to control their perceptions of pain
or pleasure. The duo are about to launch a study to determine whether women can
use fMRI as a biofeedback tool to enhance their sexual pleasure.
watch their own brain images during different kinds of self-stimulation to
determine ‘what works,’” explains Whipple. If a woman sees that a certain
technique activates the pleasure centers of her brain, she may just have found
her pathway to paradise. Adds Whipple, with a laugh, “We have never had any
trouble getting volunteers for our studies.”
