Optimal Waist-to-Hip Ratios in Women (an Hourglass Figure) Activate Neural Reward Centers in Men
Secondary sexual characteristics convey information about reproductive potential:- Facial symmetry, masculinity, and shoulder-to-hip ratio convey information about reproductive/genetic quality in males.
- Waist-to-hip-ratio (WHR) is a phenotypic cue to fertility, fecundity, neurodevelopmental resources in offspring, and overall health, and is indicative of “good genes” in women.
Researchers in this study used fMRI to show activation in male brain reward centers in response to WHR with redistributed body fat and similar body mass index (BMI). Brain activation to observed in bilateral orbital frontal cortex. Changes in WHR revealed activation in the anterior cingulate cortex, an area associated with reward processing and decision-making.
These findings suggest that an hourglass figure (i.e., an optimal WHR) activates brain centers that drive appetitive sociality/attention toward females that represent the highest-quality reproductive partners.

Brain decoding: MRI deciphers brain activity to figure out whether someone has been to the scene of a crime
Neuroscientists are starting to decipher what a person is seeing, remembering and even dreaming just by looking at their brain activity. They call it brain decoding.
In this video from the journal Nature, we see three different uses of brain decoding, including a virtual reality experiment that could use brain activity to figure out whether someone has been to the scene of a crime.

Russell Faust: Awesome! Now how long will it be until people are being arrested for thought-crimes by the Pre-Crime Squad?
