Zusammenfassung First paragraph (this article has no abstract) Many types of contrast sensitive neurons have been shown to maximize the mutual information between their response and the distribution of contrasts in natural images: The contrast response functions (CRF) of the fly large monopolar cell [1], cat X- and Y-retinal ganglion cells (RGC) and LGN neurons, cat V1 neurons, and macaque retinal and LGN M-cells [2,3] can be predicted from the respective contrast distributions using histogram equalization/infomax principles. However, macaque P-RGC, -LGN and V1 neurons are less sensitive to contrast than optimal information transmission would predict.
