Is it true that insects have a nervous system?

For the subquestion, yes, they do have a nervous system. You can read about the general gist of it here (caution: pathetic self-promotion): http://bioteaching.com/insect-brains-and-animal-intelligence/ (excuse the screwy picture formatting, it was from the old site design and I’m too lazy to reformat them).
