HDlive Study of Fetal Development and Behavior

Abstract

ABSTRACT We present the latest HDlive studies of fetal development and behavior during pregnancy. Marked changes of embryonic and fetal development and movement with advancing gestation were noted in the first trimester of pregnancy. Various realistic facial expressions (or facial movements) were recognized in the second and third trimesters. In particular, blinking, mouthing, swallowing, yawning, tongue expulsion, and sucking were clearly depicted. Moreover, various extraordinarily realistic features of fetal emotion-like behavior were identified. HDlive observation of fetal behavior and facial expressions may reflect the normal and abnormal neurological development of the fetus. HDlive may become an important modality in future research on fetal neurobehavioral development and assist in evaluation of the fetal brain function.
