Schematics depict how sex differences in LC dendritic morphology could affect emotional arousal. LC neurons of female rats have longer and more complex dendrites than neurons of males. Thus, the probability that LC dendrites will contact limbic afferents that terminate in the peri-LC is greater in females compared to males. This would be predicted to result in a greater magnitude of arousal in response to emotion-related stimuli.
