Human face reconstruction from monkey brain signal

US scientists can replicate the human face seen by monkeys from the brain's signal.

Based on the monitoring of macaque brain cells, researchers at the California Institute of Technology can reproduce the image of a monkey face, Digital Trends reported today.

Using magnetic resonance imaging technology, scientists discovered six areas of the monkey brain involved in facial recognition. The neurons here are called "face cells" by researchers.

Attaching the electrode to the monkey's brain to monitor the physicist's response to human visual acuity, researchers found that 205 neurons involved encoding 50 facets of a face. Combining these dimensions, scientists can reproduce the previously seen monkey face. The image is very similar to the original image.

"The brain cells we're studying are at the highest level of the optic nerve system , " said researcher Steven Le Chang. "When we find the right coordinates for the face, we can decode it to recreate the monkey face as well as predict the response of the face cells to any face . "

This technology can be applied to the reproduction of the suspect's image from the witness's memory. "Of course, if memory is activated the same number of cells as when seeing the face is still a question," Le Chang said.

Scientists intend to expand the study from anarchy to facial expressions and other objects.
