The Seba library treats Subgenual Prefrontal Cortex in 3 passages, across 2 authors (including Barrett, Lisa Feldman, Khalsa, Sahib S.).
Nature Experience Reduces Rumination and Subgenual Prefrontal Cortex Activation. Proceedings of the National Academy of Sciences 112 (28): 8567–8572.
Barrett cites Bratman et al.’s finding that nature exposure directly attenuates subgenual prefrontal cortex activation alongside rumination, positioning the region as a neural substrate of self-referential negative thought amenable to environmental intervention.

Inflammation causes mood changes through alterations in subgenual cingulate activity and mesolimbic connectivity. Biol Psychiatry 66:407–414.
Khalsa’s roadmap invokes Harrison et al.’s evidence that systemic inflammation modulates subgenual cingulate activity and mesolimbic connectivity, linking the structure to interoceptive mood dysregulation.

Inflammation causes mood changes through alterations in subgenual cingulate activity and mesolimbic connectivity. Biol Psychiatry 66:407–414.
This parallel citation reinforces that subgenual cingulate activity serves as a critical pathway through which inflammatory signals translate into affective and motivational changes.
