Subject: Why doesn't the human brain cease to function near magnetic fields.

I realized that the human brain is much like a conventional computer, in that 
it uses electrical impulses to convey information through out the body.  An 
apparent incongruacy is that man made electronic ciruits are disrupted by 
magnetic fields (or strong ones at least), and the brain doesn't.  Why does the 
human brain still work in the presence of strong magnetic fields?
