Ideally, there is only one difference in the treatment of the control and experimental subjects. This treatment is called the independent variable. The independent variable in this week's lab was the application of norepinephrine (NE) to the medial hypothalamus. However, because of the experimental design, there were several differences in the control treatment and the experimental treatment. What was at least one of these differences and how would you redesign the experiment to eliminate this (these) problems?

When the control subject's medial hypothalamus is treated with norepinephrine (NE), it has to be ensured that no other variable is changed. Redesign the experiment such that the eating and sleeping patterns of all the subjects should be similar so that confounding variables can be eliminated.

Explanation:

In case of the control experiment, all the factors are held constant and only the independent variable is changed so as to validate the changes that occur in the experimental subject.
