GLUT2-Expressing Neurons as Glucose Sensors in the Brain: Electrophysiological Analysis

Brain glucose sensing plays an essential role in the regulation of energy homeostasis. Recent publications report that neurons expressing glucose transporter GLUT2 act as glucose sensors in different regions of the brain and contribute to the control of glucose homeostasis and feeding behavior. In this chapter we describe the methods used to explore glucose sensing in genetically tagged GLUT2-expressing neurons with slice electrophysiology.
