“…While Yu et al (1996b) found clear indications that transport via the CSF played a role in the effects of paraventricular hypothalamic OT, icv manipulations turned out to be much less effective than direct bulbar administration (Yu et al, 1996a). Inside the olfactory bulb, both mitral and granule cells appear to be involved in the induction of short-and long -term potentiation (Fang et al, 2008;Osako et al, 2000Osako et al, , 2001Yu et al, 1996b). The mitral cells project directly to the supraoptic nucleus Yang, 1989, 1990;Meddle et al, 2007Meddle et al, , 2000 in addition to the more extensively explored projections to anterior olfactory nucleus, piriform cortex and medial and cortical amygdaloid nucei (Ghosh et al, 2011;Kang et al, 2011a,b;Miyamichi et al, 2011;Nagayama et al, 2010;Shipley, 1985;Sosulski et al, 2011).…”
