Fetal facial expressions are useful parameters for assessing brain function and development in the latter half of pregnancy. Previous investigations have studied subjective assessment of fetal facial expressions using four-dimensional ultrasound. Artificial intelligence (AI) can enable the objective assessment of fetal facial expressions. Artificial intelligence recognition of fetal facial expressions may open the door to the new scientific field, such as “AI science of fetal brain”, and fetal neurobehavioral science using AI is at the dawn of a new era. Our knowledge of fetal neurobehavior and neurodevelopment will be advanced through AI recognition of fetal facial expressions. Artificial intelligence may be an important modality in current and future research on fetal facial expressions and may assist in the evaluation of fetal brain function.
