Table 2.

Mean number of cortical regions detected with either hypertrophy (increased) or atrophy + hypertrophy (Decreased + Increased) in the remaining non-operated 131 brain regions of the 28 epileptic subjects.

	Average normative values (LifeSpan)	Personalized normative values (GeoNorm)
Decreased + Increased	14 ± 6 (0.03% ± 0.015)	9 ± 4 (0.024% ± 0.01)
Increased	10 ± 6 (0.028% ± 0.015)	6 ± 4 (0.016% ± 0.01)

Percentages represent proportion of the total of cortical regions with abnormalities.
