Not a big deal, I don't think, in terms of what it might mean; but a big deal, of course, in terms of the effort involved.
We're doing it ("he" is doing it, really, though we're all involved) to learn things - mostly because it's been a year or so since he had one, but also because there've been some falls we haven't been sure of. So far we learned that Madge talks nonstop when she's stressed. We've also learned that Coco can count backwards from nineteen quite accurately and silently. There are nineteen leads attached to his head. While they were being put on, we were trying to keep the mood light by chatting. Every once in a while he'd pipe up with how many were on or how many were left. And each time he was right on the nose.
To top things off, today would be a great day to be outside since it's the first real snow all winter (and it's not likely to last). But the recording device is a bit unwieldy and I think Coco doesn't want to be seen. I have a picture which I can send to you, but, again, I'm not sure he wants it publicized. So feel free to email me if you want to see a little guy with a bunch of wires sticking out of his scalp.
