I was thinking that if you could effectively graft human memory neurons and remove them from a persons brain and keep the cells alive while the persons body dies, and then graft them onto the silicon and pass a current through it, would that person be technically reborn inside the computer?

As well if software was designed to emulate the persons former brain function from before would they be the same person as they were with their memories attached?

I graduated with a Biology degree a year and a half ago and I am un able to find a good entry level job to jump start my career. Every where I look I am told I need experience. How am I supposed to get experience if I cant get the job in the first place?!? I am now about to have a baby and the bills are kind of high, I cant afford to quit my current non bio-related job without another job in line and I do not have the time or energy to volunteer. Even the volunteer programs are hard to get into in the local aquariums and such, there are all these criteria, and you have to have so many hours and such!
