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。

We spent most of our time exploring the inner layer, which consists of the retina and its three kinds of neurons: photoreceptors, bipolar cells, and ganglion neurons.

我们花了大部分时间探索内层，它由视网膜和它的三种神经元组成：光感受器、双极细胞和神经节神经元。
