Population data for BF stimulation effects on orientation and contrast parameters of MUA and SUA. MUA sites are plotted as filled circles, SUA as open circles (a) contrast sensitivity is increased by BF stim (decreased C50 values) (b) values for both tuning height (TH) and (c) baseline-subtracted peak firing rate (Rmax) are increased (d) the Orientation selectivity index (OSI) is significantly decreased while (e) there is no systematic effect on tuning width (TW).
