The ventral temporal cortex of humans and macaques is
marked by multiple, distinct regions specialized for the
visual processing of faces and bodies. Here we
demonstrate a similar category-specific organization in
the common marmoset (Callithrix jacchus), a small, New
World monkey. By using functional magnetic resonance
imaging (fMRI) and electrocorticography (ECoG) in awake,
trained animals, we demonstrate six face-selective and
three adjacent body-selective cortical regions in the
marmoset visual cortex. These findings suggest that key
elements of ventral stream specialization for face and
body processing were present in a common anthropoid
primate ancestor at least 35 million years ago.
