CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...
