STDP is known as a learning rule that represents Hebb's law because of its credibility and the simplicity of its mechanism confirmed by detailed experiments. Researchers who value physiological plausibility are challenging to carry out learning by STDP without adopting backpropagation. In this paper, we will introduce 6 of these challenging papers and consider how STDP contributes to learning.
