Figure 7. Selected tuning curves from orientation network with random decoder weights (and thus random neuron gains).

Blue curves, before adaptation; red curves, after weak adaptation; yellow curves, after strong adaptation. Some neuron responses are suppressed after adaptation while others are facilitated, and some tuning curves shift laterally after adaptation. Dashed lines indicate adaptor orientation. [$\mu =0.2,\tau =5ms,{\tau }_a=1000ms,\eta =1$, weak stimulus magnitude C = 10, strong stimulus magnitude C = 50, test stimulus magnitude C = 10, 200 neurons].
