The Face of Controversy

Neuroscientists have long puzzled over whether our brains process and represent information according to modules (precise brain areas respond to separate and specific stimuli) or in a distributed fashion (different brain areas cooperate to represent the same stimulus). In an enlightening Perspective, [Cohen and Tong][1] discuss two fascinating neuroimaging studies that identify areas of the human brain that represent the perception of human faces and other parts of the human body ([ Downing et al .][2], [ Haxby et al .][3]). As the Perspective authors explain, one group invokes modularity and the other group invokes distributed representation to explain their results, raising the debate about modularity versus distributed representation to new heights.
