Before revision:  Our model suggests that the receptor distribution is tuned to maximize the amount of information about the olfactory environment , in accordance with the efficient coding hypothesis. The optimal receptor distribution depends on natural odor statistics, implying that a change in environment should lead to changes in receptor abundances.
After revision:  Our model suggests that the receptor distribution is tuned to maximize the amount of information about the olfactory environment . This adaptation occurs before olfactory signals are decorrelated, leading to a new regime of efficient coding in which the optimal receptor distribution depends on natural odor statistics, implying that a change in environment should lead to changes in receptor abundances.
