Week 2: Neurotransmitters and Receptor Theory

Receptors and neurotransmitters are like a lock-and-key system. Just as it takes the right key to open a specific lock, it takes the right neurotransmitter to bind to a specific receptor. Not surprisingly, as it concerns psychopharmacology, the pharmacotherapeutics that are prescribed must trigger the release of certain neurotransmitters that bind to the correct receptors in order to elicit a favorable response for the patient. The mechanism of this binding and the response that follows reflects receptor theory and lies at the foundation of pharmacology.

This week, you will continue your examination of neuroanatomy and neuroscience as you engage with you colleagues in a Discussion. You will also explore the potential impacts of foundational neuroscience on the prescription of pharmacotherapeutics.

Learning Objectives

Students will:
  • Analyze the agonist-to-antagonist spectrum of action of psychopharmacologic agents
  • Compare the actions of g couple proteins to ion gated channels
  • Analyze the role of epigenetics in pharmacologic action
  • Analyze the impact of foundational neuroscience on the prescription of medications

Pathopharmacology: Disorders of the Nervous System: Exploring the Human Brain

Dr. Norbert Myslinski reviews the structure and function of the human brain. Using human brains, he examines and illustrates the development of the brain and areas impacted by disorders associated with the brain. (15m)

Introduction to Advanced Pharmacology

In this media presentation, Dr. Terry Buttaro, associate professor of practice at Simmons School of Nursing and Health Sciences, discusses the importance of pharmacology for the advanced practice nurse. (6m)


Discussion: Foundational Neuroscience

For this Discussion, review the Learning Resources and reflect on the concepts of foundational neuroscience as they might apply to your role as the psychiatric mental health nurse practitioner in prescribing medications for patients. 

By Day 3 of Week 2

Post a response to each of the following:

  1. Explain the agonist-to-antagonist spectrum of action of psychopharmacologic agents, including how partial and inverse agonist functionality may impact the efficacy of psychopharmacologic treatments.
  2. Compare and contrast the actions of g couple proteins and ion gated channels.
  3. Explain how the role of epigenetics may contribute to pharmacologic action.
  4. Explain how this information may impact the way you prescribe medications to patients. Include a specific example of a situation or case with a patient in which the psychiatric mental health nurse practitioner must be aware of the medication’s action.

Read a selection of your colleagues’ responses.

By Day 6 of Week 2

Respond to at least two of your colleagues on two different days in one of the following ways:

  • If your colleagues’ posts influenced your understanding of these concepts, be sure to share how and why. Include additional insights you gained.
  • If you think your colleagues might have misunderstood these concepts, offer your alternative perspective and be sure to provide an explanation for them. Include resources to support your perspective.

Note: For this Discussion, you are required to complete your initial post before you will be able to view and respond to your colleagues’ postings. Begin by clicking on the “Post to Discussion Question” link and then select “Create Thread” to complete your initial post. Remember, once you click on Submit, you cannot delete or edit your own posts, and you cannot post anonymously. Please check your post carefully before clicking on Submit!
