Stress-induced aberrations in sensory processing predict worse cognitive outcomes in healthy aging adults


Figure 7. Stress-induced gating changes predict poorer cognitive outcomes. Linear regressions of predicted somatosensory gating ratios in the oscillatory domain (accounting for levels of allostatic load, relative age acceleration and their interaction) on six cognitive domain composites (Z-scores) and global cognitive function. Higher gating ratios (i.e., worse suppression of redundant sensory information, accounting for levels of stress) were predictive of poorer global cognition and poorer performance on learning, memory, attention and processing speed domains (ps < .028). All axes are fixed for each graph. 95% confidence intervals are displayed in gray for each regression line. *p < .05, **p < .005, ***p < .001.
