This new volume documents the transition from the development of electrochemical monitoring of brain function, now more than 40 years old, to fundamental neuroscience. This includes the links of molecular neuroscience to biobehavior, to a molecular understanding of neurologically-linked diseases and to the investigation of neuroactive molecules made possible by new detection methodology. This work should be of interest to a broad audience, especially those who are engaged in neuroscience research, for example in drug discovery, but are not familiar with electrochemical methodology.
