Summary of CSF parameters from grating detection studies performed on different rat strains. Dashes indicate the parameter cannot be estimated because grating frequencies below fpeak were not tested. Brown-Norway data of this study were combined for light-adapted and 0-log unit dark-adapted experiments since the display luminance in both cases is 37 cd/m2.
