Such studies consistently find that activity in certain parts of the orbitofrontal cortex increases with increasing attractiveness of faces.This neural response has been interpreted as a reaction on the rewarding nature of attractiveness, as similar increases in activation in the medial orbitofrontal cortex can be seen in response to smiling faces While most of these studies have not assessed participants of both genders or homosexual individuals, evidence from one study including male and female hetero- and homosexual individuals indicate that some of the aforementioned increases in brain activity are restricted to images of faces of the gender participants feel sexually attracted to.In many cases, humans subconsciously attribute positive characteristics, such as intelligence and honesty, to physically attractive people.Evolutionary psychologists have tried to answer why individuals who are more physically attractive should also, on average, be more intelligent, and have put forward the notion that both general intelligence and physical attractiveness may be indicators of underlying genetic fitness.
