Bookstein's schizophrenia data. 13 landmarks
in 2 dimensions, 28 individuals.
The first 14 individuals are controls. The last fourteen cases
were diagnosed with schizophrenia.
The landmarks were taken in the near midline from MR images of the brain:
(1) splenium, posteriormost point on corpus callosum; (2) genu,
anteriormost point on corpus callosum; (3) top of corpus callosum,
uppermost point on arch of callosum (all three to an
approximate registration on the diameter of the callosum);
(4) top of head, a point relaxed from a standard landmark
along the apparent margin of the dura; (5) tentorium of
cerebellum at dura; (6) top of cerebellum; (7) tip of
fourth ventricle; (8) bottom of cerebellum;
(9) top of pons, anterior margin; (10) bottom of pons,
anterior margin; (11) optic chiasm; (12) frontal pole,
extension of a line from landmark 1 through landmark 2 until it
intersects the dura; (13) superior colliculus.
