Personality can be defined along a small number of well established
dimensions, at least half of which are determined by hereditary factors.
Heredity acts on behaviour through its influence on variations in the
structure and function of neural and biochemical systems. This book
explores the biological basis of individual differences in personality
from genes to the structure, chemistry, and function of the brain and
peripheral nervous system. In addition to basic dimensions of normal
personality, the book examines the biology of several types of
psychopathology. The concluding chapter provides a psychobiological
model for personality. This thorough analysis of the pathway from gene
to personality trait will be of interest not only to biologists, but
also to psychologists and psychiatrists.
