Olfactory receptor neurons (ORNs) transform scant chemical inputs into significant neural signals. This transformation requires signal amplification. In this issue of Neuron, Ng et al. (2019) identified a mechanism by which the signals evoked by pheromones are amplified in the ORNs that selectively promote courtship behavior in Drosophila.

果蝇嗅觉受体神经元中的信号放大

嗅觉受体神经元（ORN）将很少的化学输入转化为重要的神经信号。这种转换需要信号放大。在本期《神经元》中，Ng等人。（2019）确定了一种机制，通过该机制可将信息素引起的信号在ORN中放大，从而选择性地促进果蝇的求爱行为。
