Until recently, attempts to understand and explain criminal offending have been grounded in theories from sociological, legal, and psychological perspectives. In the preceding twenty years, or so, however, some research in the field has endeavored to look at offending from a psychobiological viewpoint. This research concerns the potential consequences of the effects of neurobiological influences on brain behavior and, consequently, human behavior. This paper discusses briefly some of the specific areas of neural research currently underway, including looking at the potential consequences for behavior, as it correlates with the age-crime curve, of the effects of neurotransmission. It also considers where the field of criminological research may be heading as a result of the insights into neurobiologically induced behavior. (Contains 1 figure.)
