And this layer, as the name indicates, contains neurons — not only the photoreceptors but also bipolar neurons and ganglion neurons.

这一层，顾名思义，包含神经元——不仅是光感受器，还有双极神经元和神经节神经元。

Bipolar neurons have synapses at both ends, forming a kind of bridge — on one end it synapses with a photoreceptor, and at the other, it synapses with a ganglionic neuron, which goes on to form the optic nerve.

双极神经元在两端都有突触，形成一种桥——在一端与感光器突触，在另一端与神经节神经元突触，神经节神经元再形成视神经。
