Answer:
One good side of having a mobilephone (or giving one to a kid) is that you will have much more contact. If the person with the phone is in danger, they can call their family and/or the police. Without a phone, this may be much harder to do. A downside of a kid having a mobile phone is that they may be exposed to many things on the internet, especially with social media. They could see thing they do not wish to see, they may be bullied, or they may experience jelousy when seeing other people on social media. In my opinion, phones are a very good resource for schoolwork, watching occasional videos, seeing the news, and staying in contact with family and friends, but this is only up to a certain point.

The phrase "Neuroscientists have suggested" contributes to the meaning of the passage by showing how the advice or input of scientists can shape the way in which data is understood or applied.
The word "suggested" tells us that neuroscientists are putting forward into consideration the way in which data is understood. But this is not compulsory and what they consider is not a "law", that is why they "suggest" and not "oblige". That means that they advise.
