Evolution of the Cerebellar Sense of Self

The cerebellum is an intriguing component of the brain. In humans it occupies only 10% of the brain volume, yet has approximately 69 billion neurons; that is 80% of the nerve cells in the brain. The cerebellum first arose in jawed vertebrates such as sharks, and sharks in fact have an additional cerebellum-like structure that works as an adaptive filter. The function of shark cerebellum-like structures is to discriminate ’self’ from ’other’ in sensory inputs. With the evolution of the true cerebellum the adaptive filter functionality was adopted for motor control and paved the way for athleticism and movement finesse that we see in swimming, running, climbing and flying vertebrates.

This book uses an evolutionary perspective to open up the exciting body of work that is cerebellar research to a wide audience. Understanding the brain is of interest to many people, from many different backgrounds, and for many different reasons. Therefore, understanding cerebellum is a significant step towards the wider challenge of understanding the brain.

This book wil be of interest to neuroscientists, neurologists and psychologists, in addition to computer scientists, and engineers concerned with machine/human interactions and robotics.
