Rod bipolar cells in the mammalian retina receive synaptic input from many noisy rod photoreceptors. When photons are scarce, linear addition of inputs would swamp signals with noise. A nonlinearity at the synapse optimizes the signal to noise ratio.
哺乳动物视网膜中的视杆双极细胞接收来自许多有噪声的视杆光感受器的突触输入。当光子稀缺时，输入的线性叠加会使信号被噪声淹没。突触处的非线性优化了信噪比。
