Neurite complexity can be deduced from neurite attachment point and ending point. Examples of neurons with different levels of neurite complexity are shown. Note that neuron A and neuron B can be distinguished by total neurite length (NL). Neuron B and neuron C can be distinguished by attachment points (AP). Neuron C and neuron D can be distinguished by ending points (EP). In these examples, NLA < NLB = NLC = NLD, APB < APC = APD, and EPC < EPD.
