Unit 2 Discussion 1

Role of the Brain in Addiction

Read the Discussion Participation Scoring Guide to learn how the instructor will evaluate your discussion participation throughout this course.

Select two models of addiction from the chart appearing on pages 24–25 in the Lewis text. Compare how each model addresses the brain changes (neurological effects) associated with using a substance (or gambling) to excess. (Note that the media pieces and optional articles may be helpful to aid your understanding of the role of the brain in addiction.) Consider the relative emphasis that each model places upon the role of physiological brain functions or changes to explain addiction. Make an educated prediction regarding how well the model can adapt to emerging developments in the neuroscience of addiction.
