As opposed to creating a miniature black hole out of thin air and assuming it's perfectly feasible. Btw, I haven't watched a single episode of Star Trek in my life.

If you are that desperate for a pseudo-realistic explanation, here it is: the Sly Splicer's claw, when using the plasmid, is crawling with microscopic organisms which spread throughout the corpse, revitalizing the dead flesh. Once the organisms reach the brain, they reactivate what's left of the lower brain functions, giving life to the body. Since the cortex (higher brain functions, e.g. thinking, counting, and talking) is the first part of the brain to decay, the target resurrects as a mindless zombie.
