What are the neural mechanisms underlying critical thinking?

I had been thinking about how to improve critical thinking, which seems really critical for doing research. My questions arise:

How can we improve critical thinking particularly?

Maybe the following Ted talk helps “5 tips to improve your critical thinking“

What are the neural mechanisms underlying critical thinking?

Maybe the following podcast episode helps “Some Neuroscience of Critical Thinking Education“

Unfortunately, I am not satisfied!
