问一句话的含义

谦虚的小公鸡UID: 2961678

It was possible to demonstrate by other methods refined structural differences among neuron types; however, proof was lacking that the quality of the impulse or its condition was influenced by these differences, which seemed instead to influence the developmental patterning of the neural circuits.


这是杨鹏的难句教程中的第11句。有这么几个问题：


1)怎么知道这个which指的究竟是differences，
the quality of the impulse or its condition还是proof？


2)which以后的内容是否也是缺少证据的？杨鹏的书的说法似乎是说是，但我怎么觉得这似乎是个事实一样的东西。


谢谢各位！

1)非限制性定语从句都是就近解释那个名词
2)which是解释differences的，the quality of the impulse or its condition was influenced by theses differences都缺乏证据，后面的定语从句只是个修饰作用而已。。。
