Figure 4. — PVN neural responses and prosocial behaviour in the IEG test. (a) Males in the testosterone (T) group exhibited significantly greater levels of PVN OT-Fos colocalization than males in the saline group. (b) The amount of PVN VP-Fos colocalization did not significantly differ between saline and T groups. (c) Males in the saline group exhibited no change in prosocial behaviour over time during the IEG test. (d) Males in the T group exhibited a significant increase in prosocial behaviour over time in the IEG test. An asterisk indicates statistical significance (p < 0.05). (Online version in colour.)
