Information rates (A) and information per spike (B) for the original and two stimulus variants. The six points (±estimate of extrapolation error) at each condition are, from left to right, computed for movie 1 presented to H1 neuron 1 (60 stimulus repeats), movie 2 to neuron 1 (60 repeats), movie 3 to neuron 2 (78 repeats), movie 4 to neuron 2 (78 repeats), movie 3 to neuron 3 (320 repeats), and movie 3 to neuron 4 (320 repeats).
