When preparing this volume we were well aware that it is not possible to cover all relevant neurochemical
techniques in a single book of this length, but we have done our best to gather a group of techniques that
will have wide general interest and are applicable to many analytical problems currently faced by neurochemists
and other neuroscientists. There are also some techniques, e.g., neuroimaging methods such as
magnetic resonance imaging/spectroscopy (MRI/MRS) and positron emission tomography (PET), which
are used extensively in the neurosciences but could take up an entire volume in their own right. These are
better covered in volumes of this handbook focusing on applications of such techniques. However, we feel
that the current volume covers some very interesting techniques and that the chapters, written as they are by
active investigators, provide useful details about theory, instrumentation, potential problems, applications,
and relevant references that will be of considerable interest to both novice and seasoned investigators
