Figure 6. Some MGB neurons can discriminate between two very close frequencies.

Example of sustained responses recorded from a neuron in the MGD, exhibiting high levels of SSA when tested at two closely spaced Δfs (0.10, first and second rows; 0.04, third row). This neuron had a reduced but still high degree of adaptation for the smallest Δf tested (0.04), revealing its ability to discriminate between two very close frequencies. Details of dot rasters and PSTHs are the same as in figure 4.
