Earlier this year I
mentioned the “Jennifer Aniston neuron,” so called, which led some to believe that the representation of an entire face may be filed in
a single neuron. They reportedly touched a single neuron inside a person’s
brain and the patient reported seeing Jennifer Aniston’s face. That flew in the
face of previous beliefs that memory for faces was somewhat diffuse throughout
the brain and that the hippocampus might play a role in searching for pieces to
assemble a ‘face’ much like putting together a jigsaw puzzle. A new study was
recently released that provided some specifics related to facial encoding in a
primate brain. That’s what it so exciting about brain-function research—new
information is released quite regularly! More tomorrow.
