That is actually me in the teacher mode - Earthgirl and I had just dissected the sheep brain during Science Club, another activity offered through our large homeschool group, so I was pretty well up on finding the hippocampus - it's tiny!
This was an extra brain left over from Science Club - offered to SG gratis as a Thank You for judging the high school portion of Science Fair. I brought it home from Science Club in my lunchbag, and delivered it SG after Sunday School in a little gift bag. SG and I - we are not the squeamish types.
Speaking of hippocampus, I found this article interesting - I think I need to go take a walk!
