While they show an increasing coding fraction for larger populations, the increase is small, less than a factor of 2. +The cells in the next quartile interval show on average only a slightly lower coding fraction for a population size of 1 than the cells in the first quartile interval. Their rise is much faster however, and somewhere between 4 and 8 cells they begin showing a higher coding fraction than the cells in the first quartile. +Cells in the third quartile interval have on average a coding fraction half as large as the cells in the first quartile for a single neuron. With increasing population size, the growth in coding fraction also becomes steeper and between 32 and 64 cells their average coding fraction passes the average coding fraction of the cells in the first quartile interval. +The noisiest cells which make up the fourth quartile interval (largest $\sigma$, red) start with the lowest coding fraction on average for small populations. For a single cell, the coding fraction is on average only about a quarter of the cells in the first quartile interval. The increase of coding fraction with increasing population size is quite slow at first, an effect we have also seen with very noisy cells in our simulations (see figure \ref{cf_limit} b)). For increasing population sizes the coding fraction increase becomes larger. +These results qualitatively do not depend on the choice of separating the cells into quartiles.
