"Psychophysical evidence (33, 34) supports the proposal that the neural
representation of faces may be based on such dimensions, represented as
opponent processes referenced to the population mean. This opponent process
model demonstrates how a limited number of channels can represent complex
variations of form, such as those that distinguish one face from another,
and suggests, further, how a limited cortical space could represent an
unlimited variety of faces."
