Fig. 2From: Abnormal alterations of regional spontaneous neuronal activity and functional connectivity in insomnia patients with difficulty falling asleep: a resting-state fMRI studyCortical areas of increased/decreased ALFF in ID patients compared with HC. The red color shows increased spontaneous functional activity in the right amygdala and the left insula in ID patients. The bule color shows decreased spontaneous functional activity in the right superior parietal lobule in insomnia patients. SPL, superior parietal lobule; L, left; R, rightBack to article page
