and unzip or open that bag up and bring out 
your lead wires, run the animal, then place the 
leads in and sew it up again. So far this is 
looking very promising. I'd be interested in 
other people's experiences with this approach. 
Dr. Mortimer: I think that's fine. I think 
there's a lot of alternate techniques that are 
certainly going to be appropriate, and the more 
you have, the more options an investigator will 
have. For us, if we want to run them contin- 
uously, we need to take the data off daily and 
I think this doesn't lend itself too well to doing 
that repeated surgery. It is a tedious operation, 
and using the spring connector has been the 
way out for us on this. The reason we're forced 
to use it is the method of injecting this elec- 
trode. If we put a connector on it that we can 
handle, we can't get it in through our hypo- 
dermic needle when we try to pull it back 
through.
