A Hierarchical Neuronal Model for Generation and Online Recognition of Birdsongs

Figure 10

Third simulation ‘Differently wired brains’: For simplicity, we only show the causal states of the generation (left column) and recognition (right column), where the format is the same as in Figure 5 with arbitrary units.

The connectivity matrices ('s) at the second level are different in the singing bird (generation) and in the listening bird (recognition). Recognition still works as well as in the first simulation (‘Ideal communication’, Figure 7) because third level ensembles can compensate for this variability by providing different input to the second level (different I vectors).
