As previously reported (Suo et al., 2006; Yoshida et al., 2014),
ser-3 and
ser-6 were expressed in a number of neurons including the SIA neurons in hermaphrodites.
octr-1 was also expressed in the SIA neurons of hermaphrodites. Furthermore, expression of
ser-3,
ser-6, and
octr-1 in the SIA neurons was similarly observed in males.
