Oxidative metabolism in fetal rat brain during maternal halothane anesthesia.

The present study examines the effects of maternally administered halothane on fetal brain metabolism as determined by direct tissue analysis. Term pregnant rats were paralyzed, ventilated, and administered halothane in concentrations of 0.4, 1, or 2%. For comparison of fetal response to anesthetic agents, other maternal rats were administered pentobarbital (50 or 200 mg/kg). Dams receiving 0.4...

The impact of COVID-19 during pregnancy on fetal brain development

The development of the brain as the most complex structure of the human body is a long process that begins in the third week of pregnancy and continues until adulthood and even until the end of life (1). Human brain myelination begins one to two months before birth in the visual system and eventually lasts until the age of two in other sensory systems and then the motor systems (4). Processes a...

Fetal habituation correlates with functional brain development.

In this study, we divided 26 fetuses at 32-37 weeks of gestation into three groups using combined criteria of gestational age and behavioral indicators. We investigated fetal habituation to vibroacoustic stimulation (VAS). Fetuses showed habituation from at least 32 weeks of gestation. Furthermore, fetuses less developed from behavioral standpoint took significantly more trials to achieve habit...
