Using Cultured Mammalian Neurons to Study Cellular Processes and Neurodegeneration: A Suite of Undergraduate Lab Exercises.

ABSTRACT

Cell culture is a powerful tool for exploring cellular function. Culturing primary neurons has revealed how neurons communicate in learning and memory (Kandel, 2006) and provided insights into the mechanisms of neurodegenerative diseases such as Parkinson's and Alzheimer's disease (Alberio et al., 2012; Trinchese, et al., 2004). Here we describe a series of four modular laboratory exercises to integrate this neuroscience technique in undergraduate teaching laboratories. First, we describe the modular approach. Then we provide educators with simple techniques for culturing rat primary neurons, performing immunohistochemistry to label cellular components, and illustrating neurodegeneration caused by reactive oxygen species. We describe teaching exercises that culminate in student-generated research projects. Finally, we describe potential barriers students may face when integrating modern cell culture experiments into teaching laboratories.
