Case 4

Brain Workouts

In this module, you will complete a  directed case. This type of case study is designed to enhance your understanding of fundamental concepts, principles, and facts. The case consists of a short, dramatic scenario accompanied by a set of “directed” questions. Some of the answers to the questions can be found in the textbook or the lectures, while other questions may require you to do additional research. 

Objectives

1. Connect neuronal structures and actions involved in synaptic formation and maintenance.

2. Explain what neurotrophins are and how they affect neurons.

3. Contrast two ideas concerning what is helpful for brain functioning and memory.

PSB3002 –– Module 4 – Development of the Brain Case Study Worksheet – Brain Workouts All questions must be answered to earn full credit. Partial work is graded with the posted rubric. Kindly consider using a different color for your answers to help with grading workflow. This case study has 8 required questions including 1 drawing. Name: Part I – Back from Break 1. What is brain plasticity? 2. What is the term that refers to the formation of new neurons? 3. What term refers to the genetically programmed death of neurons in the brain? Is this genetically programmed neuronal death only found in the brains of people with Alzheimer’s disease? Part II – Last Semester’s Notes 1. Explain what dendritic spines, sprouting, branching, and arborization are and how these concepts relate to synapses. Then, draw a picture that you could share with Anthony and Darrell that demonstrates these concepts and that will help them understand. Be sure to label the neurons’ other relevant structures, as well. Paste drawing here. 2. Anthony is correct that there are chemicals in the brain that help neurons survive, help promote neural growth, and are involved in neurogenesis. What are these chemicals called? What are two main ones that you’ve learned about? Do all neurons receive these chemicals? Why or why not? 3. Darrell’s father used the phrase, “use it or lose it.” What neuronal activities are related to this idea? 4. Darrell’s dad insists that there are scientific research findings supporting his claim that playing brain games helps one’s brain and keeps memory from declining, whereas Anthony’s dad insists that there are scientific research results supporting his claim that physical exercise helps one’s brain and slows memory decline. Based on what you’ve learned about synapses and about the chemicals that promote neural survival and growth, is one of the dads correct? Is neither correct? Are both correct? Give evidence to support your answer. 5. Which of these two “brain workouts” do you believe would be the most beneficial for you as you experience adulthood and aging? Why? Which of these brain workouts do you believe would be the most beneficial for you in terms of learning material in your current college classes? Why?
