Researchers discovered that axes within a multidimensional space, now known as the “face space” can combine in different ways to create every possible face. In other words, there is no Jennifer Aniston neuron. Senior author Doris Tsao, a professor of biology and biological engineering at the California Institute of Technology reported: “We’ve discovered that this code is extremely simple. We can now reconstruct a face that a monkey is seeing by monitoring the electrical activity of only 205 neurons in the monkey’s brain. One can imagine applications in forensics where one could reconstruct the face of a criminal by analyzing a witness’s brain activity.” More tomorrow.
