Summary: Previous work has shown that lesion of the pre-Bötzinger Complex (pre-BötzC) of rats with SP-SAP (Cat. #IT-07) results in hypoventilation and an abnormal breathing pattern. The authors used 1 or 10 µl of 50 pM SP-SAP bilaterally injected into the pre-BötzC area to further investigate this system in goats. The results show transient changes in respiratory rhythm and respiratory muscle activation patterns, indicating that SP receptor-expressing neurons in the pre-BötzC are involved in the regulation of respiration.
