Neonatal preference for visual patterns: modification by prenatal anesthetic exposure?
Exposure to anesthetic drugs during gestation has been shown to cause behavioral changes in rats, and exposure during labor and delivery also affects human neonatal behavior. In this preliminary study, nine neonates who had been exposed to anesthetic agents during gestation were tested for visual-pattern preference. These nine infants looked at the stimuli for statistically significantly longer periods compared with 30 non-exposed infants, and had significantly different preferences for some pairs of patterns. The results suggest that prenatal exposure to anesthetic agents may contribute to behavioral alterations in human neonates.
