The lipophilic dye, DiI, was placed into the macula lagena of paraformaldehyde-fixed embryonic chicks. Retrogradely labeled cells were found bilaterally in the pontine reticular formation (RF) between the dorsal facial nucleus and the abducens nerve root. This location is similar to that of the dorsomedial group of efferent cells that project to the basilar papilla. No lagenar efferent neurons, however, were found near the superior olivary nucleus where the ventrolateral group of cochlear efferents is located. Whether efferent neurons in the pontine RF send collaterals to both the basilar papilla and to the macula lagena has yet to be determined.
将亲脂性染料DiI注入经多聚甲醛固定的胚胎小鸡的听斑。在双侧脑桥网状结构（RF）中，位于面神经背核与展神经根之间发现了逆行标记的细胞。该位置与投射至基底乳头的传出细胞背内侧组的位置相似。然而，在耳蜗传出神经腹外侧组所在的上橄榄核附近未发现听斑传出神经元。脑桥RF中的传出神经元是否向基底乳头和听斑都发出侧支，还有待确定。
