Neurochemistry is the study of the cellular and subcellular components of the nervous system and the molecules found within it. The nervous system is complex and neurochemistry a diverse field in which there has been much interest recently, for example in the increased awareness of pathological brain conditions such as Alzheimer's disease, depression, and mania. A wide range of techniques are avialable to the neurochemist and this volume contains the core elements of neurochemistry that will be useful to both first time researchers and established investigators in all fields of neuroscience.
