Table 1.

Demographic information and mean fiber bundle lengths.

N = 73 participants (25 males, 48 females)
Variable	Mean	SD	Min	Max
Demographics^a
Age at MRI (years)	63.56	8.59	51	85
Education^b (years)	15.38	2.53	11	20
Mean Fiber Bundle Length (mm)
Frontal Lobe	33.21	2.85	27.7	40.21
Insula	28.07	6.44	16.19	47.26
Temporal Lobe	27.41	2.96	21.06	35.58
Parietal Lobe	31.37	3.32	22.22	41.46
Occipital Lobe	34.46	5.11	21.42	48.74

Demographics were calculated after one outlier was removed prior to analysis (see text).

Education was measured as highest year of school completed.
