Introduction to Neuroscience 2: Lecture 15: appetite

In this lecture, we learn about brain and hormonal mechanisms that regulate appetite and feeding. We learn about the two competing feelings, hunger and satiety. I then discuss the role of the hypothalamus in regulating these feelings, with focus on four hormones: ghrelin, leptin, PYY, and orexin. I present the two types of neurons found in the arcuate nucleus and how the counterbalance each other to regulate satiety and hunger. We also learn how the body creates these hormones and how they affect activity in the arcuate. Then we discuss clinical conditions related to feeding, and finish with a discussion of role of genetics and obesity.
