Abstract
To evaluate the development of the convolutional
pattern of the cerebral hemispheres a total of 123
brains of Korean fetuses of gestation ages ranging
from 12 to 44 weeks was studied. The fetuses were
products of artificial ahortions, and were proved to
be normal after complete examination of fetuses and
placentas. The brains were removed as soon as pos .
sible after delivery, and were fixed in 10% formalin
for one week before being examined for this study.
It was quite consistent feature that gyral development
started to appear from 20 weeks gestation age
around the Sylvian fissure. The sequential develop·
mental changes of the individual fissures, sulci and gyri of cerebral hemispheres throughout the
gestational period are tabulated.
It was concluded that the pattern of gyral development
of Korean fetuses is comparable to that of
other countries, and could be used as a parameter of
maturation in the developing brains.
