Premature births-a week in an incubator

Where would I find studies on prematurity and psychological and physical growth into adulthood. Amongst other things, I wanted to find out if it is true that premature babies are more sensative to touch as the result of having their nerves closer to the skin? What could be some psychological results of not making contact with a mother for a week? If you have some info I would appreciate it.

Also, an Alta Vista search on “premature+birth” returned many sites, including a whole category of “premature birth - effects”.
