摘要: Publisher Summary This chapter focuses on neuroimaging techniques, explaining their relevance to understanding drug addiction. There are two main divisions in techniques: structural and functional. The former measures features of brain structure such as its size, shape, density. Functional magnetic resonance imaging (fMRI) exploits the fact that property blood changes when oxygen is removed. can be detected using an MRI paradigm known BOLD signal. Structural technique volume shape with reasonable precision. It used investigate potential differences brains certain populations. endorphin system major target for opioid drugs morphine heroin. has long been implicated processes interpersonal bonding, love, and, lacking, pain.
