Neonatal studies suggest elevated arousal can negatively influence perceptual and cognitive processes during early development. The authors explored this issue during the prenatal period by pharmacologically elevating physiological arousal in bobwhite quail (Colinus virginianus) embryos during exposure to a maternal call, then assessing preference for the familiar call following hatching. Embry...

It has been known that methadone maintenance treatment is the standard treatment of choice for pregnant opiate addicts. However, there are few data on newborn outcomes especially in the cross talk with other addictive agents. The present study was to investigate the effect of prenatal exposure to methadone on methamphetamine (METH)-induced behavioral sensitization as an indicator of drug addict...

It has been well documented in a host of animal studies that the development of an individual is beset by a complex set of environmental influences during the prenatal period. Prenatal stresses, in particular, are known to significantly influence brain development and behavior in the affected fetuses 1) . Considerable experimental and clinical evidence has been collected, and appear to indicate...

Increasingly, the diagnoses of chest lesions in infants are made not by symptoms of respiratory distress but by prenatal imaging. Because the availability and quality of prenatal imaging have increased, so has the frequency of prenatal diagnoses that include symptomatic and asymptomatic lesions. Early prenatal diagnosis of life-threatening lesions, such as congenital diaphragmatic hernia (CDH) ...

We present a case of a female infant that was diagnosed on prenatal ultrasound with an oral mass, and subsequently underwent a planned EXIT procedure to secure the airway. Ultimately the epignathus teratoma was excised at 3 days of age. The number of cases in which neonates have survived epignathus teratomas has increased in the past decade due to improved prenatal imaging and the development o...

Related experiments examined the effects of attenuated prenatal sensory stimulation on subsequent postnatal auditory and visual responsiveness in precocial bobwhite quail chicks {Colinus virginianus). Results revealed that denying quail embryos the prenatal vestibular and tactile stimulation provided by broodmates during incubation alters preand postnatal perceptual functioning. Chicks incubate...

Prenatal stress could have great influence on development of offspring and might alter cognitive function and other physiological processes of children. The current study was conducted to study the effect of physical or psychological prenatal stress on addictive and anxiety-like behavior of male and female offspring during their adolescence period (postnatal day (PND) 40). Adult female rats wer...

BACKGROUND Serotonin influences the development of the hypothalamic-pituitary-adrenal (HPA) system; therefore prenatal exposure to selective serotonin reuptake inhibitor antidepressants (SSRIs) may alter HPA axis development and function. To address this, prenatal exposure to SSRIs and maternal mood were examined in relation to neonatal and infant levels of cortisol and its binding protein, cor...

BACKGROUND Epidemiological studies have linked maternal infection during pregnancy to later development of neuropsychiatric disorders in the offspring. In mice, experimental inflammation during embryonic development impairs behavioral and cognitive performances in adulthood. Synaptic dysfunctions may be at the origin of cognitive impairments, however the link between prenatal inflammation and s...
