Mad Cow Disease (medically known as bovine spongiform encephalopathy, or BSE), is an incurable and fatal brain disease. It affects cows of and kind, and possibly some other animals including goats and sheep (Nemours). When humans are infected it is known as Creutzfeldt-Jakob Disease or CJD, and has much the same effect as it does on animals. How it is transferred from animal to animal, and animal to human is still not yet well understood. The theory that is most currently probable is that the disease is transferred by an abnormal protein known as a prion protein and then consumed (CDC). This disease causes tiny holes in the brain that when looked at under a microscope the brain appears to be spongy (NINDS). These holes are causes by the abnormal protein that were consumed. Below is a picture of two human brains; QuickTime and a TIFF (Uncompressed) decompressor are needed to see this picture. the left side is the brain of a person who died from Mad Cow Disease, and the brain on the right is from a healthy deceased person (NINDS). You can see the obvious shrikage of the brain itself, and how the solid parts look as if they are not as dense as the healthy 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
