Outline of Final Research Achievements

How does the human brain convert sensory inputs into conscious percepts? This is an unsolved and controversial issue in neuroscience, because some researchers argued that the conscious percepts emerge from collective neural activity over a broad region in the brain while others argued that they emerge from feedback signals from higher to lower brain regions. Here we focused on feedforward (rather than feedback) neural signals at a long latency (about 200-300 ms after a stimulus onset) and showed its critical role in conscious perception.
