大脑回路处理奖励和厌恶刺激被假设为动机行为的核心。在这项研究中，离散类别的美丽的面孔被证明有不同的奖励价值和差异激活奖励回路在人类受试者。特别是，年轻的异性恋男性认为美丽的男性和女性的照片是有吸引力的，但通过按键过程只会看到有吸引力的女性的照片。3T的功能性磁共振成像显示，被动观看美丽的女性面孔会激活奖励回路，特别是丘脑核。一组扩展的皮层下和边缘皮层奖励区域似乎也遵循按键方面，而不是评级程序，这表明奖励电路功能不包括美学评估。
The brain circuitry processing rewarding and aversive stimuli is hypothesized to be at the core of motivated behavior. In this study, discrete categories of beautiful faces are shown to have differing reward values and to differentially activate reward circuitry in human subjects. In particular, young heterosexual males rate pictures of beautiful males and females as attractive, but exert effort via a keypress procedure only to view pictures of attractive females. Functional magnetic resonance imaging at 3 T shows that passive viewing of beautiful female faces activates reward circuitry, in particular the nucleus accumbens. An extended set of subcortical and paralimbic reward regions also appear to follow aspects of the keypress rather than the rating procedures, suggesting that reward circuitry function does not include aesthetic assessment.
