This week we had a discussion about how the LH and VMH in your brain affects your hunger and how much or little a person eats. To understand these to subjects, we did an online experiment about stimulating and destroying both the LH and VMH in a rats brain, and then watching them to see how much they ate and then gained weight. When the LH is destroyed in the hypothalamus, you are going to eat less, and when it is stimulated you are going to eat more. When the VMH is destroyed you cannot stop eating, and when it is stimulated you are going to eat way less. It's amazing to me how these two parts in the hypothalamus work together and regulate someone's hunger. I found an article on this subject.....

This article really hit on all the points we went over in class, and sums it all into about a page which I liked. A great study tool!

I was also intrigued by how a simple stimulation or destruction of certain areas the hypothalamus could cause such dramatic changes in the eating habits of a rat. It's just amazing how the brain works. How everything we think, do, or plan to do all starts with the brain. The brain is constantly at work 24/7.
