From: Responses of the human visual cortex and LGN to achromatic and chromatic temporal modulations: An fMRI study Journal of Vision. 2010;10(13):13. doi:10.1167/10.13.13 Figure Legend: Temporal cone contrast sensitivity functions measured psychophysically on 2 of our 6 subjects (KTM and RFH) for the same stimuli as used in the fMRI experiments (black lines: achromatic stimuli, red lines: L/M-cone opponent stimuli, blue lines: S-cone opponent stimuli). Data points and solid lines show means and SE of data combined across subjects. Data points and dashed lines show the detection thresholds obtained at 16 Hz for L/M-cone opponent and S-cone opponent stimuli, which were achromatic in appearance at this temporal frequency, whereas data points with solid lines show thresholds for detection of color at 16 Hz. (For all other temporal frequencies, chromatic stimuli all appeared colored at detection threshold.)
