The functional architecture of temporal frequency preference of human visual system is not well characterized. We collected fMRI data with visual stimuli varying flicker frequency from 1 to 40 Hz. Using model fit and K-means clustering on frequency tuning curve we were able to show evidence for a temporal frequency specific architecture of visual system.
