Fetuses show various facial expressions, such as blinking, yawning, sucking, mouthing, tongue expulsion, scowling, and smiling, assessed by four-dimensional ultrasound from the early second trimester of pregnancy. Moreover, some fetuses demonstrate emotion-like behaviors as noted in infants, children, and adults. Selective fetal responses to stimuli indicate a high degree of brain development, which is reflected in the facial reactions. The fetal face with its movements and expressions can mirror the fetal brain function and development during different stages of the fetus in utero. The fetal face might represent the key to opening the box containing the secrets of fetal brain function and development. Four-dimensional ultrasound may be an important modality in current and future research on fetal facial expressions and assist in the evaluation of the fetal brain function.
通过妊娠中期早期的四维超声评估发现，胎儿会表现出各种面部表情，如眨眼、打哈欠、吸吮、张嘴、伸舌、皱眉和微笑。此外，一些胎儿会表现出类似婴儿、儿童和成人的情感行为。胎儿对刺激的选择性反应表明其大脑发育程度较高，这在面部反应中有所体现。胎儿的面部动作和表情能够反映其在子宫内不同阶段的大脑功能和发育情况。胎儿的面部可能是打开包含胎儿脑功能和发育秘密之盒的钥匙。四维超声可能是当前及未来胎儿面部表情研究中的一项重要手段，并有助于评估胎儿脑功能。
