Editorial: Where the rubber meets the road in visual perception: high temporal‐precision brain signals to top‐down and bottom‐up influences on perceptual resolution.

2020 
Analysis of human brain responses from various neuroimaging techniques (EEG, S-EEG, ECoG, or MEG) to visual stimuli in both the time- and the time-frequency domain have provided means for researchers to understand the early stages of visual perception in humans. In the time-domain, event-related potentials (ERPs) have been used as neurocognitive tools to study a wide range of cognitive processing in humans, e.g. attention, vigilance, arousal, since the 1960's (e.g. Haider et al. 1964; Spong et al. 1965; Eason et al. 1969). Importantly, the early neurophysiological studies also drew attention to the importance of carefully characterizing the visual stimulus - to account for non-linear behavior of ERPs especially Steady State Visual Evoked Potentials (van der Tweel & Lunel, 1965; van der Tweel & Spekreijse, 1969).
