摘要
The retina adapts to average light intensity but also to the range of light intensities (contrast). A study by Baccus and Meister, in this issue of Neuron, identifies three ways that ganglion cells and interneurons adapt to high contrast: shorten integration time, reduce gain, and depolarize. Only the depolarization decays, over tens of seconds.
