| Research Abstract |
We studied how the brain orders events in time by applying methods in psychophysics and neuroimaging. We also recorded neural activities from behaving monkeys to elucidate why temporal order judgment is reversed when two successive visual stimuli are delivered just prior to the onset of saccadic eye movements. Results generally agreed with our hypothesis(motion projection hypothesis) that the temporal order of events is determined by combining spatial representations of stimuli in the parietal and prefrontal cortices with representations of" motion" or" changes" in the multisensory perisylvian cortex.
