Psychology- Neurotransmitter systems and their repercussions in behavioral addiction

Resources: Make sure you read chapters 3 and 4 of your text, Biological Basis of Behavior (2013). How does chemicals which are foreign to your body, such as alcohol, have an effect? How does your body produce its own chemicals (neurotransmitters)? Any type of chemical whether it is natural or synthetic can have a physical effect and/or a psychological effect. These chapters explore these aspects of human behavior. In section 3.4, there is a wonderful table of drugs and their effects that I encourage you to read. This week you will have 2 options to choose from for your assignment: Option A: Evaluate one of the neurotransmitters covered in this week’s readings. Explain the role it plays in modulating responses to a drug of abuse. For example, you could choose the acetylcholine receptor system and discuss the role this neurotransmitter plays in addiction to nicotine. In addition to your evaluation of the specific neurotransmitter and its associated receptor system, provide correlation to the involved neuroanatomical structures, the contribution of genetics and environment to the development of dependence, tolerance, and addiction to this substance, as well as clinical treatment interventions. Option B: Evaluate one of the neurotransmitters covered in this week’s readings. Explain the role it plays in a neurological or psychological disorder of your choice. For example, you could choose the dopaminergic system and discuss the role this neurotransmitter has in the development of schizophrenia. In addition to your evaluation of the specific neurotransmitter and its associated receptor system, provide a correlation to the involved neuroanatomical structures, as well as the contribution of genetics and environment to the development and clinical management of this disorder.
