A rapid switch in neural code may solve debate about face recognition

May 12, 2026

new study published in Nature from the lab of HWNI member Doris Tsao, professor of neuroscience and Pivotal Life Sciences Faculty Scholar, has found that face-selective neurons in the brain initially respond to images of any object, but then rapidly switch to responding specifically to faces once a face is shown. This dynamic change in neuronal tuning may resolve a debate in the field over whether these cells respond specifically to facial features or more broadly to a wider range of visual stimuli. These findings could also provide a new model for AI systems, using a changing code rather than a stable one. Read more about the study from The Transmitter.
