Well, last weekend I dissected a preserved sheep brain. The previous week a colleage (a Science teacher with whom I co-teach the elective “Frontiers in Science”) brought me a fresh-from-the-butcher sheep brain, and we spent 20 minutes exploring it. The brain was soft and squishy. Having been partially frozen, as it melted it became almost like goop. Wish I had my camera, as it was easy to pick up or point out individual parts.
The preserved brain I dissected over the weekend was quite firm, making it easy to cut and hold, yet because it was preserved the brain seemed more like a plastic model. On May 3rd the “Frontiers in Science” class will dissect sheep brains, and the brains we will provide will be half from the butcher and half preserved brains.
My next goal is to further study individual brain parts, and for this I am hoping to borrow a microscope from school.
