Our faces convey a wealth of information to an observer, which is base
d on both static and dynamic cues. It is the static cues, such as the
shape and configuration of facial features, which give rise to the mor
e obvious cues signalled by a face: identity, gender, and attractivene
ss. However, dynamic movements of the facial muscles signal important
social information such as the emotional state and the direction of at
tention of an individual. Recent advances in the functional imaging of
the human brain function, combined with studies of brain-damaged pati
ents, have allowed us to localize those regions of the brain which med
iate the recognition and interpretation of facially-conveyed informati
on, and allow a greater understanding of these regions' purpose and fu
nction.
