Can you simply talk about the relationship between the brain's reaction speed and neural circuits from a biological point of view?

The brain's reaction speed is related to subjective and objective factors:

The objective factor is the release rate of neurotransmitters (serotonin, dopamine, etc.). ), affecting the transmission of "electrical signal-chemical signal-electrical signal" between neurons, and people with innate advantages in this respect are extremely agile;

Subjective factor is the accumulation of brain knowledge base. The richer the knowledge stored in all aspects, the more information you can get when you think, and you often need answers sent back quickly, so you think this person is quick.
