Figure 6A

Photomicrograph showing retrogradely labeled neurons in the lateral part of the periaqueductal gray at the level of the oculomotor nucleus after a large CTb injection site in the rat LC+periLC. Note the anterograde labeling of the dorsal noradrenergic bundle situated ventrolaterally to the periaqueductal gray.
