||"[Researchers] computed the
thickness of the cortical gray matter for the left hemisphere of
30 subjects (17 male and 13 female, ages 20–37 years old)."
||"[Researchers] find that gyral regions have an average thickness
of 2.7±0.3 mm, versus 2.2±0.3 mm for sulcal regions...Across the 30 subjects, [they] find that approximately 90% of the cortex consistently maps
gyral/sulcal patterns across individuals. That is, a patch of cortex that is clearly gyral
(or sulcal) in one individual has a 90% chance of mapping to a gyral (or sulcal) patch in any
other individual. Note that 100% alignment is not possible because of the fact that the
topology of the folding patterns varies substantially across individuals, and thus no
continuous bijection exists."
