Braiiiinz: a dissection. Just in time for Halloween! (Warning, photos of actual brains)

TMS Biology teacher Heather Parker joined Fred Kral's Psychology class to lead a sheep brain dissection lab.

Did you know, the sheep brain and human brain are very similar in overall structure (as are all mammalian brains). However, a sheep's brain is about about one-tenth of the weight of an adult human brain. A major difference is that the relative size of the frontal lobe—an indicator of species intelligence—is much smaller in sheep than humans.

Though the sheep has generally been regarded as an unintelligent animal, it is increasingly recognized that sheep are able to perform some advanced tasks, such as remembering the faces of other sheep and humans for two years or longer.
