#1. What is the difference between stimulation of the right vagus versus the left vagus? How are they connected to the heart? What would you expect to see upon left vagus stimulation?

Overview of Lab Protocol

You will directly record live arterial blood pressure and the rate and relative depth of respiration of the anesthetized rat. Sections of small diameter polyethylene tubing (i.e., cannulas) will be inserted into the left jugular vein (for injecting drugs) and into the right carotid artery (for directly recording the BP). A force-displacement transducer will record the rhythmical chest movements associated with inhalation and exhalation. All data will be recorded via LabScribe.

#2 Suggest at least one additional treatment or related experiment you could do with this preparation. What would you do, what would it test, what might you expect to happen?
