[Individual anatomical variability of the head of the caudate nucleus and of the putamen in man].

Individual variabilities in form, size and position of the nucleus caudatus head and the putamen have been studied in the horizontal section cutting across the inferior edge of the interventricular foramen (Monro) and the posterior commissure of the cerebrum in 70 mature persons died from various diseases not connected with disorders in the brain. Variability in length, width and position of these strial structures have been estimated taking into account the size of the intercommissural lines. The investigation has demonstrated that with an increasing distance between the anterior and posterior commissures of the cerebrum, the length and width of the nucleus caudatus head and those of the putamen increase; these nuclei are observed to be pushed off the median line and approach towards the level of the anterior cerebral commissure.
