In neurodegenerative diseases, the golgi ribbon of a specific group of neurons is typically broken into isolated elements, a very early event which happens before clinical and other pathological symptoms become evident.
What is the golgi apparatus, and why are we asking. The structure that camillo golgi first observed was a typical mammalian golgi, with individual stacks that are linked to form long connected ribbons arranged around the microtubule organizing center near the nucleus.
