    Sheep Brain Dissection

    Dissection of sheep brain

    Above: Posterior view of a sheep brain

    Sheep brain dissection images. The dark-colored top of the cortex is called “gray matter.” The inner, lighter layer is called “white matter.” Gray matter gets its color from the dark nuclei of the brain’s cell bodies.The axon of each brain cell reaches out through the brain to make connections with other brain cells. It is through these connections that billions of brain cells relay information to billions of other brain cells creating a communication network that makes thought possible.

    Above: Difference in size and appearance between a human brain and a sheep brain. A slice of the cerebral cortex of the sheep brain is taken to reveal the pattern of gray matter and white matter.
