PET imaging reveals brain metabolism of orgasmic reactions
Dutch researchers may have done more to recruit radiologists than any public relations campaign ever could. They've used PET imaging to probe the brains of men and women before and during sexual orgasm.
Dutch researchers may have done more to recruit radiologists than any public relations campaign ever could. They've used PET imaging to probe the brains of men and women before and during sexual orgasm.
One finding showed that parts of women's brains, including those that govern emotional control, essentially shut down during orgasm. The same areas imaged during a faked orgasm were rife with FDG.
Areas of women's brains that control fear and anxiety, such as the amygdala, begin to deactivate during sexual activity, closing down at orgasm. In addition, women don't seem to rely as much as men on direct sensory input from the genitals. In men, the secondary somatosensory cortex, which rates the significance of physical sensations, showed greater FDG activity than in women.
Reliable data on men, however, were sparse because their orgasm needed to last a few minutes to compare scans before and during climax.
Dr. Gert Holstege, from the University of Groningen, reported the study at the European Society of Human Reproduction and Embryology meeting in July.
New CT and MRI Research Shows Link Between LR-M Lesions and Rapid Progression of Early-Stage HCC
January 2nd 2025Seventy percent of LR-M hepatocellular carcinoma (HCC) cases were associated with rapid growth in comparison to 12.5 percent of LR-4 HCCs and 28.5 percent of LR-4 HCCs, according to a new study.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
