Adaptation is a key component of efficient coding in sensory neurons. However. it remains unclear how neurons can provide a stable representation of external stimuli given their history-dependent responses. Here we show that a stable representation is maintained if efficiency is optimized by a population of neurons rather than by neurons individually. https://www.aitsglobal.com/product-category/%d7%97%d7%92%d7%99%d7%9d/
