PET scan voyeurism

a study has found a new way to figure out if she's faking it, if you happen to have a PET scanner or two lying around the house:
The women were asked to lie with their heads in a PET scanner while the team compared their brain activity in four states: simply resting, faking an orgasm, having their clitoris stimulated by their partner’s fingers, and clitoral stimulation to the point of orgasm.

The results of the study are striking. As the women were stimulated, activity rose in one sensory part of the brain, called the primary somatosensory cortex, but fell in the amygdala and hippocampus, areas involved in alertness and anxiety. During orgasm, activity fell in many more areas of the brain, including the prefrontal cortex.

...[The] study also revealed clear differences when women were faking an orgasm. Part of the brain involved controlling conscious movement lit up, and there was none of the extreme deactivation [seen during orgasm].

from new scientist via pure pedantry

and as for the boys, apparently for them it all happens so quickly that the changes in brain activity cannot be measured - PET scanners just aren't precise enough yet. so it will be a while before us grrls would know if this book is worth the paper it is printed on
