C. What happens to baroreflex function during descending activation of the parabrachial nucleus? Please include what neurotransmitters are released in the medulla and how these might contribute to associated changes in reflex gain changes in response to parabrachial activation? D. How does a change in inhibitory inputs (afferents or receptors) in the hypothalamus of individuals with cardiovascular disease contribute to a change in resting blood pressure and respiratory rate? Please provide how some of the brain regions identified in "a." above may be altered (greater excitation/inhibition). .
