Algorithm can recreate faces based on brain activity

The code used by the brain to recognise faces may finally have been cracked by a mind-reading computer. Scientists programmed an algorithm that is able to recreate images of faces shown to monkeys in astonishing detail by measuring brain activity. The findings seem to solve one of the most difficult problems in neuroscience - and researchers say the explanation is surprisingly simple. The discovery could lead to software in the future that allows machines to probe further into our minds. Researchers have made a computer algorithm that is able to accurately recreate faces seen by macaque monkeys by measuring their brain activity.
