| Outline of Final Research Achievements |
We found that a fetus may prepare for feeding after birth in the second half of pregnancy. Moreover, frequencies of complicated facial expressions such as smiling and scowling may increase with advancing gestation due to the development of the fetal brain and central nervous system. First study using KANET suggests that ethnicity should be considered when evaluating fetal behavior, especially during assessment of fetal facial expressions. Scond study suggests that the level of relaxation of pregnant women may affect fetal behavior, particularly the rate of eye blinking. Third study suggests that 4D ultrasound study examining fetal behavior does not need to consider the factor of fetal sex.
During this study period, we disclosed the characteristics of fetal facial expressions in the second half of pregnancy. Moreover, we are the first to document the usefulness of KANET test for evaluating fetal brain and central nervous system in Japan.
