Delineating each addition to the 63 chapters covering new
developments, techniques, and knowledge in neuroscience would
require excessive space. Generally speaking, the progression of
the chapters has remained the same, with relevant additions made
to each to deal with new developments. Most of these additions,
as already noted, fall into the molecular arena. A new chapter,
"Genes and Behavior," is presented in part 1 and provides the
foundation for genetic topics in subsequent chapters. The "Genes
and Behavior" overview describes very cogently the multiple
avenues for exploration of the genetic determinants of behavior,
including single gene allele determinants of normal variations
in behavior, as well as the effects of mutations, deletions, and
other defects in manifest behaviors. This introduction does an
exceptional job of setting the stage for the remainder of the
text. The broad scope of this text is exemplified in the
introduction as it overviews genetic findings in worms,
Drosophila, and mice, bridgin
