A fundamental problem in neuroscience is the elucidation of the cellular
and molecular mechanisms underlying the development and function of the
nervous system. The complexity of organization, the heteroge- neity of
cell types and their interactions, and the difficulty of controlling
experimental variables in intact organisms make this a formidable task.
Because of the ability that it affords to analyze smaller components of
the nervous system (even single cells in some cases) and to better
control experimental variables, cell culture has become an increasingly
valuable tool for neuroscientists. Many aspects of neural development,
such as proliferation, differentiation, synaptogenesis, and myelination,
occur in culture with time courses remarkably similar to those in vivo.
Thus, in vitro methods often provide excellent model systems for
investigating neurobiological questions. Ross Harrison described the
first culture of neural tissue in 1907 and used morphological methods to
analyze the cultures. Since that time the technique has been
progressively modified and used to address an ever widening range of
developmental questions. In recent years a con- vergence of new or
improved cell culture, biochemical, electrophysiol- ogical, and
immunological methods has occurred and been brought to bear on
neurobiological questions. This volume is intended not to be
comprehensive but rather to highlight some of the latest findings, with
a review of previous important work as well, in which combinations of
these methods are used.
