The serotoninergic system plays an important role in the ontogeny of the mammalian central nervous system, and changes in serotonin production during development may lead to permanent changes in brain cytoarchitecture and function. The present study investigated the programming effects of neonatal serotonin depletion on behavior and molecular components of the serotoninergic system in adult male and female rats. Subcutaneous para-chlorophenylalanine (pCPA) administration (100 mg kg-1 ) was performed daily on postnatal days 8-16 to deplete brain serotonin content...

Background: Sleep is an important determinant of brain development in preterm infants. Its temporal organization varies with gestational age (GA) and post-menstrual age (PMA) but little is known about how sleep develops in very preterm infants. The objective was to study the correlation between the temporal organization of quiet sleep (QS) and maturation in premature infants without severe complications during their neonatal hospitalization. Methods: Percentage of time spent in QS and average duration of time intervals (ADI) spent in QS were analyzed from a cohort of newborns with no severe complications included in the Digi-NewB prospective, multicentric, observational study in 2017-19...

Perinatal asphyxia (PA) is an obstetric complication occurring when the oxygen supply to the newborn is temporally interrupted. This health problem is associated with high morbimortality in term and preterm neonates. It severely affects the brain structure and function, involving cortical, hippocampal, and striatal loss of neurons. Nearly 25% of PA survivor newborns develop several neurodevelopmental disabilities. Behavioral alterations, as well as the morphological and biochemical pathways involved in PA pathophysiology, have been studied using an animal model that resembles intrauterine asphyxia...

Neonatal intensive care units (NICUs) greatly expand the use of technology. There is a need to accurately diagnose discomfort, pain, and complications, such as sepsis, mainly before they occur. While specific treatments are possible, they are often time-consuming, invasive, or painful, with detrimental effects for the development of the infant. In the last 40 years, heart rate variability (HRV) has emerged as a non-invasive measurement to monitor newborns and infants, but it still is underused. Hence, the present paper aims to review the utility of HRV in neonatology and the instruments available to assess it, showing how HRV could be an innovative tool in the years to come...

Testosterone masculinizes male sexual behavior by providing organizational and activational effects during the perinatal and peripubertal periods and during adulthood, respectively. We revealed that the emission of ultrasonic vocalizations (USVs) and mounting behavior was regulated by different neural circuits. However, the detailed testosterone effects on these two behaviors have not been fully elucidated. Here, we evaluated the time-dependent effects of testosterone on USVs and mounting behavior in mice using a testosterone treatment model, in which females were treated with testosterone to assess the "gain-of-function" and a "loss-of-function" model...

Electroacupuncture (EA) therapy via alternating current stimulation on the scalp over the motor cortex is used for the treatment of brain disorders. Perinatal hypoxia-ischemia (HI), a brain injury in newborns, leads to long-term neurologic complications. Here, we investigated whether EA could promote functional improvements and neurogenesis in a neonatal HI rat model. A neonatal HI rat model was induced by permanent ligation of the left carotid artery in postnatal day 7 pups. EA for neonatal HI rats was performed at 2 Hz (1, 3, or 5 mA; 20 min) from 4-6 weeks after birth...

Prenatal opioid exposure (POE) has shown to be a risk factor for adverse long-term cognitive and behavioral outcomes in offspring. However, the neural mechanisms of these outcomes remain poorly understood. While preclinical and human studies suggest that these outcomes may be due to opioid-mediated changes in the fetal and early postnatal brain, other maternal, social, and environmental factors are also shown to play a role. Recent neuroimaging studies reveal brain alterations in children with POE. Early neuroimaging and novel methodology could provide an in vivo mechanistic understanding of opioid mediated alterations in developing brain...

The time course of changes in functional cortical activity during early development has been extensively studied in the rodent visual system. A key period in this process is the time of eye opening, which marks the onset of patterned visual input and active vision. However, vision differs from other systems in that it receives limited patterned sensory input before eye opening, and it remains unclear how findings from vision relate to other systems. Here, we focus on the development of cortical network activity in the olfactory system-which is crucial for survival at birth-by recording field potential and spiking activity from piriform cortex of unanesthetized rat pups from birth (P0) to P21...

Introduction: Umbilical granuloma (UG) is the most common cause of umbilical mass and it is formed in the first few weeks of life after the umbilical cord separates. Though there are different options of treatment described in the literature, there is no clear consensus on the best option of treatment. In our case, we will describe the complete resolution of granuloma with salt treatment with no adverse effect. Case Presentation: An 18-day-old female infant presented to the outpatient department (OPD) with concerns of swelling over the umbilicus with a yellowish discharge of one-day duration noticed after separation of the umbilical cord...

Introduction: We have reported previously that hydrogen-rich saline (HS) plays a neuroprotective role in hypoxia-ischemia (HI) brain damage in newborn mice. However, the mechanisms for this neuroprotection resulting from HS remain unknown. In this study, we examined the potential for HS to exert effects upon microglial phagocytosis via involvement of the Akt signaling pathway as one of the neuroprotective mechanisms in response to neonatal HI. Methods: The HI brain injury model was performed on postnatal day (PND) 7 (modified Vannucci model)...

The opioid crisis has resulted in an unprecedented number of neonates born with prenatal opioid exposure (POE); however, the long-term effects of POE on offspring behavior and neurodevelopment remain relatively unknown. The advantages and disadvantages of the various preclinical POE models developed over the last several decades are discussed in the context of clinical and translational relevance. Although considerable and important variability exists among preclinical models of POE, the examination of these preclinical models has revealed that opioid exposure during the prenatal period contributes to maladaptive behavioral development as offspring mature including an altered responsiveness to rewarding drugs and increased pain response...

BACKGROUND: During the first period of life, critically ill as well as healthy newborn infants experience recurrent painful procedures. Parents are a valuable but often overlooked resource in procedural pain management in newborns. Interventions to improve parents' knowledge and involvement in infants' pain management are essential to implement in the care of the newborn infant. Neonatal pain research has studied a range of non-pharmacological pain alleviating strategies during painful procedures, yet, regarding combined multisensorial parent-driven non-pharmacological pain management, research is still lacking...

Disrupted-in-schizophrenia 1 (DISC1) gene represents an intracellular hub of developmental processes. When combined with early environmental stressors, such as maternal immune activation, but not in the absence of thereof, whole-brain DISC1 knock-down leads to memory and executive deficits as result of impaired prefrontal-hippocampal communication throughout development. While synaptic dysfunction in neonatal prefrontal cortex (PFC) has been recently identified as one source of abnormal long-range coupling, the contribution of hippocampus (HP) is still unknown...
