Three types of DSTRF variations are shown over time for three example sites that exhibit each of these types more prominently. The DSTRFs have been masked by 95% significance per jackknifing (). (A) The STRF of the three example sites. (B) Example site E1: Gain change of DSTRF, shown as the time-varying magnitude of the DSTRF at three different time points. Although the overall shape of the spectrotemporal receptive field is the same, its magnitude varies across time. E2: Temporal hold property of an DSTRF, seen as the tuning of this site to a fixed spectrotemporal feature but with shifted latency (lag) in consecutive time frames. E3: Shape change property of DSTRF, seen as the change in the spectrotemporal tuning pattern for different instances of the stimulus. (C) From top to bottom, distribution of gain change, temporal hold, and shape change values for sites in HG and STG. Horizontal lines mark quartiles. Temporal hold and shape change show significantly higher values in the STG.
