OXT and Anxiety: The amygdala plays a crucial role in fear- and anxiety-related processes (see, e.g., Phelps and LeDoux, 2005; Mihov et al., 2013; however, see also LeDoux and Pine, 2016; Gothard, 2020; Zhou et al., 2021), and both OXT and 5-HT effects on the amygdala have been repeatedly documented (Cools et al., 2005; Fisher and Hariri, 2013; Kanat et al., 2015; Raab et al., 2016; Xin et al., 2020; Kreuder et al., 2020).
