When a particular joke goes over well with one sex and not the other, you might chalk it up to biology. Apparently, there are differences in humor appreciation between the sexes.
When a particular joke goes over well with one sex and not the other, you might chalk it up to biology. Apparently, there are differences in humor appreciation between the sexes.
Using functional MRI, Stanford University researchers found that women and men had similar neurological responses to a series of black-and-white cartoons. Women, however, tended to make greater use of the nucleus accumbens, implying greater reward network response (Proc Natl Acad Sci USA 2005;102[45]:16496-16501).
The nucleus accumbens is associated with psychological reward, including situations of self-reported happiness, monetary reward, the processing of attractive faces, and cocaine-induced euphoria.
Researchers said that insight into these sex differences may aid in understanding the pathogenesis of neuropsychiatric disorders, most notably depression, an affliction that strikes twice as many women as men, with dramatic effects on the capacity to experience reward.
Can Contrast-Enhanced Mammography be a Viable Screening Alternative to Breast MRI?
June 17th 2025While the addition of contrast-enhanced mammography (CEM) to digital breast tomosynthesis (DBT) led to over a 13 percent increase in false positive cases, researchers also noted over double the cancer yield per 1,000 women in comparison to DBT alone.
FDA Clears Enhanced MRI-Guided Laser Ablation System
June 5th 2025An alternative to an open neurosurgical approach, the Visualase V2 MRI-Guided Laser Ablation System reportedly utilizes laser interstitial thermal therapy (LITT) for targeted soft tissue ablation in patients with brain tumors and focal epilepsy.
Possible Real-Time Adaptive Approach to Breast MRI Suggests ‘New Era’ of AI-Directed MRI
June 3rd 2025Assessing the simulated use of AI-generated suspicion scores for determining whether one should continue with full MRI or shift to an abbreviated MRI, the authors of a new study noted comparable sensitivity, specificity, and positive predictive value for biopsies between the MRI approaches.
