Destruction of the paraventricular nucleus (PVN) with electrolytic lesions has been shown to produce hyperphagia (overeating) in rats. Injections of local anesthetic into the PVN may also stimulate eating. Likewise, injections of NE into the PVN also produce feeding in rats. What does this information suggest about the effect of NE on the firing rate of neurons in the PVN? A general principle relating changes in the rate of neural firing to changes in the rate of a specific behavior (such as feeding) can be derived from this information. What is this principle?

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
