Pale skin and hanging eyelids are tell-tale signs of apparent illness.

The tool cannot predict a person’s face from DNA, say researchers—including some listed as coauthors on the publication. 

The brains of Polistes paper wasps express different genes when identifying faces than when distinguishing between simple patterns, a study finds.

Researchers could reconstruct the faces a monkey saw from the patterns of neuronal activity in a certain area of the brain.

Dogs trained to stay still in an MRI machine show activity in the temporal cortex when shown a human face.

Ron Blackwell helps neuroscientists map the circuitry of face perception by letting them stimulate his brain with electricity.

For neuroscientists, experimental results converge to help crack the case of how the brain functions.

Once dominated by correlational studies, face-perception research is moving into the realm of experimentation—and gaining tremendous insight.
