Bodznick Co-Authors Book on Cerebellar Sense of Self

bodznickIn human beings, the cerebellum occupies only 10 percent of the brain volume, yet has approximately 69 billion neurons; that is 80 percent of the nerve cells in the brain.

In the book Evolution of the Cerebellar Sense of Self, published by Oxford University Press in January, co-authors David Bodznick and John Montgomery use an evolutionary perspective to explain cerebellar research to a wide audience. Bodznick is professor of biology, professor of neuroscience and behavior at Wesleyan, and Montgomery is professor of biology and marine science at the University of Auckland in New Zealand.

The cerebellum first arose in jawed vertebrates such as sharks, and early vertebrates also have an additional cerebellum-like structure in the hindbrain. Shark cerebellum-like structures function as so-called adaptive filters to discriminate ‘self’ from ‘other’ in sensory inputs.

According to Bodznick, “it is likely that the true cerebellum evolved from these cerebellum-like precursors, and that their adaptive filter functionality was adopted for motor control; paving the way for the athleticism and movement finesse that we see in all swimming, running, climbing and flying vertebrates,” he said.

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