Psychological stress produces detectable activation patterns in functional MRI scans
Multiple functional neuroimaging studies demonstrate that psychological stress elicits reliable and detectable activation patterns across various brain regions, including the prefrontal cortex, insula, and amygdala.
The claim asserts that psychological stress produces detectable activation patterns in functional MRI scans. Multiple papers in the provided set directly use fMRI to measure and identify distinct neural activation, connectivity, and hemodynamic changes induced by psychological stressors. Therefore, the claim is strongly supported by the literature.

The study utilizes functional MRI to demonstrate that psychological stress tasks produce detectable patterns of neural activation in brain areas such as the cingulate and prefrontal cortices.
