Could you help me with this sentence, please?
"There are prominent differences between neonatal and adult brain, and the understanding of how are neural networks forming in the childhood could give us the insights into how are this networks processing information in the adulthood."
1) Should I use "the brain", just "brain" or maybe "brains", when I'm comparing neonates and adults?
2) Should I use a continuous form in the second part of the sentence? Is it possible to say "how do they form...", "how do they process ..." instead?
