Conceived and designed the experiments: SMP DS. Performed the experiments: Analyzed the data: Wrote the paper: Contributed stimuli for experiments: Secondary sexual characteristics convey information about reproductive potential.
Relative to presurgical bodies, brain activation to postsurgical bodies was observed in bilateral orbital frontal cortex. While changes in BMI only revealed activation in visual brain substrates, changes in WHR revealed activation in the anterior cingulate cortex, an area associated with reward processing and decision-making.
Hips regressing ratings of fat on brain activation, we observed activation in forebrain substrates, notably the nucleus accumbens, women forebrain nucleus highly involved in reward processes.
These findings suggest that an hourglass figure i. This is the first description of a neural correlate implicating WHR as a putative honest biological signal of naked reproductive viability and angela baron xxx effects on men's neurological processing. Variations in men's facial e.
