    and Harvard In 2004 he moved to Bremen Germany to lead a research group at the Centers for Advanced Imaging and Cognitive Science In work published in 2006 and 2008 Freiwald and his long time collaborator Doris Tsao presently a professor of biology at Caltech identified a network of face areas which they called face patches in the brains of rhesus monkeys Similar areas had been found in the human brain Freiwald was appointed assistant professor at Rockefeller in 2009 He regards the face patch system as a uniquely powerful model to explore how the primate brain recognizes objects But he notes A face isn t just any object It demands special attention and conveys very potent social and emotional information After Freiwald arrived at Rockefeller he began to take advantage of faces unique significance to the human brain He now uses face processing as a model to investigate how the brain couples visual perception to memory attention emotion and communication Discovering and exploring new brain systems The specialized circuitry of the face patch system provides an entry point from which to study the neural basis for intelligence Predicting what other people will do arguably is the greatest challenge for the human mind Freiwald says And it solves this challenge successfully with very minimal clues from the face How is that even possible What the human brain lacks in sheer data processing power he notes it more than makes up for through a different type of intelligence Instead of crunching large sets of numbers the human brain constructs rich models of the world to make deep inferences about it For instance facial recognition may require the brain to alter its internal model of a face to match what the eyes see Face processing is a case in point because when
