Instructions: Answer the following questions in complete sentences.

1. Describe the process of neural transmission, including the roles of the axon, dendrites, synapse, and neurotransmitters. Be sure to include a description of the action potential.

2. Compare and contrast the functions of the sympathetic and parasympathetic nervous systems. Provide examples of how each system affects the body.

3. Explain the contributions of at least three different brain imaging techniques (e.g., EEG, fMRI, PET scan) to our understanding of brain function. Discuss the strengths and limitations of each technique.

4. Discuss the relationship between genetics and behavior, providing examples of how genes can influence psychological traits and predispositions.
