Arm immobilization induces a local decrease in cortical SWA. Inflated cortical maps showing (left side) the ratio of the sum of currents during the first 100 milliseconds of the left arm SEPs before and after 12 hours of arm immobilization and (right side) subsequent NREM sleep of the first sleep cycle relative to cortical SWA of NREM sleep of the first sleep cycle following a normal day. The white outline circumscribes the statistically significant region (SnPM suprathreshold cluster test, corrected for multiple comparisons, p<0.05) of decreased cortical SWA in the frontal and parietal cortices following arm immobilization. Both the SEP and SWA ratios are on the same scale.
