Nature experience reduces rumination and subgenual prefrontal cortex activation

What the study found

A nature walk reduced self-reported rumination and subgenual prefrontal activation relative to an urban walk.

Limitations

Short-term exposure; route differences extend beyond vegetation; small sample for neuroimaging.

Neurodesign interpretation

The paper is powerful because it links landscape exposure to a neural process associated with repetitive negative thought. The translation to interiors remains an inference.

Possible design implications

Use access to nature and restorative walking routes as a design opportunity, while avoiding claims that indoor greenery reproduces the same neural effect.

Why it stays in the corpus

Retain as a canonical neural-mechanism paper for nature exposure.
