  1. SF denotes spatial frequency; SNR refers to signal-to-noise ratio. Eccentricity is the distance from the central fixation to the stimulus center. Acquisition of structural data is indicated by sMRI (structural magnetic resonance imaging). Parameters in Experiment 4 were optimized to enhance ERPs (event-related potentials).
