Images of GABAergic neurons in proximity to CVNs.

<p>a. In this confocal image, CVNs in the NA are labeled with rhodamine and are surrounded by smaller GABAergic cell bodies and terminals labeled with GFP. b. The 800 µm thick transverse medullary slice preparation from P3–P6 mice has all the necessary circuitry for respiratory rhythm generation including the preBötC, respiratory hypoglossal motorneurons and intact hypoglossal nerve rootlets, and the NA.
