Wilshere has noticed a distinct change in the environment of the England camp since he returned to the international fold under Hodgson, who was appointed to replace Fabio Capello in May.
He said: "It's totally different from before. For one, the manager has changed and all the staff have changed, too, so it's a totally different atmosphere. It's a nice atmosphere.
"There are more English people around and we get on really well and are more relaxed.
"We have some good young players now and some with experience, so it's important we have got a good blend and it worked well (against Brazil)."
