Intensity-based cluster analyses of the LC structure. A Cluster analyses on MRI signal intensity within the LC mask revealed two distinct clusters along the LC structure, one covering the middle-to-caudal LC (orange, cluster 1) and the other covering the middle-to-rostral LC (green, cluster 2). B Box plots of MRI signal intensity within clusters 1 and 2, represented by hemisphere. Paired t test analyses showed that MRI signal intensity in cluster 1 is significantly lower than that in cluster 2. *p < .05, **p < .001
