Final Question for my EPQ

I have decided to focus my project on specifically bi/multilingual children’s brain as I have realised, from the sources online, that focusing on the whole concept of bi/multilingual brain is broad and it has many factors which affects it. Given the complexity of the brain, I have understood that being bilingual is an evolving process and the age of acquisition of a language is another factor which affects this process. This, in particular, is the reason why I decided to focus on individuals who learn two or more languages from an early age.

I started this project with the intention of focusing on the whole journey of being bi/multilingual and how the brain develops throughout time. However, this is a really long and complex development and also there isn't enough reliable, peer-reviewed researches which track the whole journey. I decided to focus on the sub-topic I am most interested in, the developing brain of a child, and do more in depth research on this. Therefore my question changed from "Is there a difference between the Bi/Multilingual and Monolingual Brain?" to "Is there a difference between the Bi/Multilingual and Monolingual Brain in children?". 

I also plan to include some of the social sides of this practice and how external environmental factors, such as upbringing and childhood, can affect how the person views languages.
