OXT and Anxiety: For example, among high-anxiety rodent dams, the levels of intracerebral release of OT correlates with maternal aggression toward a virgin intruder (Bosch et al., 2005), and in low-anxiety strains, synthetic OT infusion in the paraventricular nucleus through retrodialysis increases maternal intruder-directed aggression (Bosch and Neumann, 2012).
