Neuroscientist Doris Tsao finds flickering brain signals in monkey vision
University of California Berkeley researcher Doris Tsao shared a preprint study on October 17 about macaque brain activity patterns.
Conscious and unconscious visual patterns
The team recorded neural signals from macaques during a visual perception experiment. Their data showed strong signals for both seen objects and unseen images in front of the animals eyes. Previous research had only found weak signals for content the monkeys did not perceive.
Reconstruction of hidden images
Researchers used only neural activity to rebuild high fidelity images of what the animals saw. They also successfully reconstructed pictures that were present but escaped the monkeys awareness. This discovery surprised the scientist because the signals were unexpectedly strong.
Social media reaction to study
Tsao posted her summary on social media platforms ten days after the initial preprint release. The post quickly gained more than two million views and 11,000 likes from readers. She described the public response to her findings as surreal.
