Across-site patterns for six psychophysical measures in two subjects (one subject per column). The measures are from the top absolute detection threshold (T level), maximal comfortable level (C level), modulation detection threshold (MDT), modulation detection threshold in presence of a masker on the electrode immediately basal to the probe (masked MDT), gap-detection threshold (GDT), and slope of the multipulse integration function (MPI slopes). All measures were obtained using an MP 1+2 configuration. The supra-threshold functions were measured at levels corresponding to 50% of the site’s dynamic range. More information about methods used to collect these types of data can be obtained from previous publications from this laboratory. For T levels, C levels and MDTs and masked MDTs, see Garadat et al., 2012 or Zhou and Pfingst, 2012. For GDTs see Garadat and Pfingst, 2011. For MPI slopes see Zhou et al., 2012 or 2014a).
