Infant faces provide a powerful stimulus, which also elicits sex differences in behavior and brain responses that appear dependent on sex hormones.
There are many facial dimensions affecting perceptions of attractiveness that remain unexplored in neuroimaging, and we conclude by suggesting that future studies combining parametric manipulation of face images, brain imaging, hormone assays and genetic polymorphisms in receptor sensitivity are needed to understand the neural and hormonal mechanisms underlying reproductive drives.

For heterosexual individuals there is a common brain circuit involving the nucleus accumbens, the medial prefrontal, dorsal anterior cingulate and the orbitofrontal cortices that is activated more by attractive than unattractive faces, particularly for faces of the opposite sex.
Behavioral studies indicate parallel effects of attractiveness on incentive salience or willingness to work to see faces.
Infant faces activate brain regions that partially overlap with those responsive to adult faces.
The Cruisin' Gourmet music has been replaced; in doing so, a cue was missed (after "The bird is dead") and the laugh track has been replaced with a different (and much worse) one.
The end credits music has been replaced with the generic theme.

Sex differences and similarities in response to facial attractiveness are reviewed.
