The development of anticipation in the fetus: A longitudinal account of human fetal mouth movements in reaction to and anticipation of touch

Research suggests that fetuses open or close their mouth in relation to directed movements but it is unclear whether mouth opening anticipates the touch or is a reaction to touch, as there has been no analysis so far of (1) the facial area of touch and (2) the sequential ordering of touch and mouth movements. If there is prenatal development of the anticipation of touch we would expect the frequency of fetal mouth opening immediately preceding the arriving hand at the mouth area to increase with fetal age. Fifteen healthy fetuses, eight girls and seven boys, underwent four additional 4-D scans at 24, 28, 32, and 36 weeks gestation. Changes in the frequency of touch for different facial regi…
