Finding a face place in monkeys’ brains
By Bruce Bower
Monkeys recognize a wide variety of faces thanks to a brain area that specializes in face perception, according to a new study.
A team led by Doris Y. Tsao of Harvard Medical School in Boston used functional magnetic resonance imaging (fMRI) to identify three particularly face-responsive patches of brain tissue in each of two macaque monkeys. The researchers then implanted electrodes in each monkey’s most-active brain area to record responses from a total of 310 neurons.
