Single-unit and multiunit recordings in primates have already established that decision making involves at least two general stages of neural processing: representation evidence from early sensory areas accumulation to a threshold decision-related regions. However, the relay information areas, such process is instigated, not well understood. Using cued paradigm single-trial analysis electroencephalography (EEG), we previously reported on temporally specific components related perceptual making. Here, use derived our previous EEG inform fMRI data collected for same behavioral task ascertain cortical origins each these components. We demonstrate cascade events associated with takes place highly distributed network. Of particular importance an activation lateral occipital complex implicating persistence as mechanism by which object human brain instigated.
