The Swarm

An interesting episode that finds Voyager in a very precarious area of space, from which no ship has made it through safely. The first signs of trouble are when B'Elanna and Tom Paris run into a energy shield that damages their neural pathways. To compound Voyager's problems, the Emergency Medical Hologram a.k.a. The Doctor seems to be unraveling - losing his memory and his skills. This allows the story to get into interesting Doctor territory all the while raising interesting questions about what constitutes humanity and personality.
