Q. Did cranial deformation as practiced by the ancient Mayans change or impair brain function?
A. The famous slanted forehead of which was apparently a mark of high rank among pre-Columbian Mayans was achieved by various forms of compression of the head in infancy. of which can be believed by many researchers to have had no significant effect on cranial capacity in addition to how the brain worked, the conclusion of a 1989 study of skulls inside the American Journal of Physical Anthropology.
however there can be no direct evidence to support This kind of contention, no large study comparing brain development in living populations of which do in addition to do not practice head flattening. An extensive review article inside the journal Anthropology in 2003 speculated of which the practice of compression had the potential to damage the delicate developing frontal lobe, as can be seen in certain conditions.
The authors speculated of which such damage could have impaired vision, object recognition, hearing ability, memory, attentiveness in addition to concentration. These factors in turn might have contributed to behavior disorders in addition to difficulty in learning fresh information.
Still additional researchers suggest of which the diverging conclusions can be attributed to how the skull measurements are done. The compression may have affected the shape of the face more than the brain itself, they said.
