| This is a section of a mouse cerebellum (from the Latin “little brain”). Located at the lower back of the brain, the cerebellum receives and sends information to other organs. Accordingly, this information processing center contains more than 50% of the total neurons in the brain. To accommodate such a large number of cells in a small space, the outer region of the cerebellum is thrown into folds, or lobules. In this photomicrograph, every red dot indicates one single cell that is undergoing cell division. Conditions such as schizophrenia, autism, mood disorders, dementia, and attention deficit hyperactivity disorder (ADHD) are all thought to be disorders of cerebellar function. |
