UC Berkeley neuroscience research on conscious perception

Overview

Neuroscientists at the University of California, Berkeley, led by Janis Hesse and Doris Tsao, have conducted research into how the brain processes sensory information and distinguishes between conscious and unconscious perception.

Initial studies involving macaques and humans suggested that the brain may switch between conscious and unconscious processing approximately 15 times per second to prevent cognitive overload. Subsequent research utilized binocular flash suppression and Neuropixels probes to observe neural activity in the inferotemporal and prefrontal cortices of monkeys. This work revealed that specific neuron populations rapidly alternate between representing perceived and suppressed images in intervals of roughly 60 milliseconds. The findings, published in the journal Science, indicate that consciousness is tied to fine-scale temporal neural activity rather than just the location of specific neurons.
