Which part of the brain is also called "little brain"?

All vertebrates have a cerebellum, which is known as the "small brain" in Latin. In some animals, such the mormyrid fishes, it may be as big as or even bigger than the cerebrum, despite the fact that it is typically smaller. The cerebellum is a key component of human motor control. Although its movement-related functions are the most well-established, it may also be involved in some cognitive processes like attention and language as well as emotional control processes like regulating fear and pleasure responses. The human cerebellum does not start movement, but it does help with coordination, precision, and correct timing by receiving information from other areas of the brain and from sensory systems in the spinal cord and integrating it to control motor activity.
