Abstract
The complex organization of brain regions during development requires a three-dimensional approach to facilitate the visualization and quantification of dynamic changes taking place throughout this important period. Using the tissue clearing method combined with immunohistochemistry, three-dimensional (3D) lightsheet microscopy and a multiresolution registration technique, we provide the first 3D atlases of the main cholinergic (CH) and catecholaminergic (CA) systems in the mouse brain from embryonic day 12 (E12) to post-natal day 8 (P8). We report that in several brain structures, there is a logarithmic scale increase of choline acetyltransferase and tyrosine hydroxylase positive neurons from E18 to P8. In addition, a detailed voxel-wise analysis revealed abrupt modifications in the developmental trajectory of many brain structures during the transition from E18 to P0. Our atlases will not only facilitate developmental studies aimed at quantitatively determining the fate of CH or CA neurons in utero but also be used as an anatomical reference to quantify other neuronal populations present in the annotated regions. In the future, these maps will be a reliable tool to study developmental malformations associated with neurological and psychiatric disorders.

Abstract
The third trimester of pregnancy represents a sensitive phase for infant brain plasticity when a series of fast-developing cellular events (synaptogenesis, neuronal migration, and myelination) regulates the development of neural circuits. Throughout this dynamic period of growth and development, the human brain is susceptible to stress. Preterm infants are born with an immature brain and are, while admitted to the neonatal intensive care unit, precociously exposed to stressful procedures. Postnatal stress may contribute to altered programming of the brain, including key systems such as the hypothalamic-pituitary-adrenal axis and the autonomic nervous system. These neurobiological systems are promising markers for the etiology of several affective and social psychopathologies. As preterm birth interferes with early development of stress-regulatory systems, early interventions might strengthen resilience factors and might help reduce the detrimental effects of chronic stress exposure. Here we will review the impact of stress following premature birth on the programming of neurobiological systems and discuss possible stress-related neural circuits and pathways involved in resilience and vulnerability. Finally, we discuss opportunities for early intervention and future studies.

Abstract
All mammals must suckle and swallow at birth, and subsequently chew and swallow solid foods, for optimal growth and health. These initially innate behaviors depend critically upon coordinated development of the mouth, tongue, pharynx, and larynx as well as the cranial nerves that control these structures. Disrupted suckling, feeding, and swallowing from birth onward-perinatal dysphagia-is often associated with several neurodevelopmental disorders that subsequently alter complex behaviors. Apparently, a broad range of neurodevelopmental pathologic mechanisms also target oropharyngeal and cranial nerve differentiation. These aberrant mechanisms, including altered patterning, progenitor specification, and neurite growth, prefigure dysphagia and may then compromise circuits for additional behavioral capacities. Thus, perinatal dysphagia may be an early indicator of disrupted genetic and developmental programs that compromise neural circuits and yield a broad range of behavioral deficits in neurodevelopmental disorders.

Abstract
The extracellular matrix protein Reelin is an important orchestrator of neuronal migration during the development of the central nervous system. While its role and mechanism of action have been extensively studied and reviewed in the formation of dorsal laminar brain structures like the cerebral cortex, hippocampus, and cerebellum, its functions during the neuronal migration events that result in the nuclear organization of the ventral central nervous system are less well understood. In an attempt to delineate an underlying pattern of Reelin action in the formation of neuronal cell clusters, this review highlights the role of Reelin signaling in the migration of neuronal populations that originate in the ventral brain stem and the spinal cord.

Abstract
OBJECTIVE Velopharyngeal hypotonia seems to be an important factor in velopharyngeal dysfunction in 22q11.2 deletion syndrome, but the etiology is not understood. Because TBX1 maps within the typical 22q11.2 deletion and Tbx1-deficient mice phenocopy many findings in patients with the 22q11.2 deletion syndrome, TBX1 is considered the major candidate gene in the etiology of these defects. Tbx1 heterozygosity in mice results in abnormal vocalization 7 days postnatally, suggestive of velopharyngeal dysfunction. Previous case-control studies on muscle specimens from patients and mice revealed no evidence for a myogenic cause of velopharyngeal dysfunction. Velopharyngeal muscles are innervated by cranial nerves that receive signals from the nucleus ambiguus in the brainstem. In this study, a possible neurogenic cause underlying velopharyngeal dysfunction in Tbx1 heterozygous mice was explored by determining the size of the nucleus ambiguus in Tbx1 heterozygous and wild type mice. METHODS The cranial motor nuclei in the brainstems of postnatal day 7 wild type (n=4) and Tbx1 heterozygous (n=4) mice were visualized by in situ hybridization on transverse sections to detect Islet-1 mRNA, a transcription factor known to be expressed in motor neurons. The volumes of the nucleus ambiguus were calculated. RESULTS No substantial histological differences were noted between the nucleus ambiguus of the two groups. Tbx1 mutant mice had mean nucleus ambiguus volumes of 4.6 million μm(3) (standard error of the mean 0.9 million μm(3)) and wild type mice had mean volumes of 3.4 million μm(3) (standard error of the mean 0.6 million μm(3)). Neither the difference nor the variance between the means were statistically significant (t-test p=0.30, Levene's test p=0.47, respectively). CONCLUSIONS Based on the histology, there is no difference or variability between the volumes of the nucleus ambiguus of Tbx1 heterozygous and wild type mice. The etiology of velopharyngeal hypotonia and variable speech in children with 22q11.2 deletion syndrome warrants further investigation.

Abstract
We present a biobehavioral model that explains the neurobiological mechanisms through which measures of vagal regulation of the heart (e.g., respiratory sinus arrhythmia) are related to infant self-regulatory and social engagement skills. The model describes the sequential development of the neural structures that provide a newborn infant with the ability to regulate physiological state in response to a dynamically changing postpartum environment. Initially, the newborn uses primitive brainstem-visceral circuits via ingestive behaviors as the primary mechanism to regulate physiological state. However, as cortical regulation of the brainstem improves during the first year of life, reciprocal social behavior displaces feeding as the primary regulator of physiological state. The model emphasizes two sequential phases in neurophysiological development as the fetus transitions to postpartum biological and social challenges: 1) the development of the myelinated vagal system during the last trimester, and 2) the development of cortical regulation of the brainstem areas regulating the vagus during the first year postpartum.

Abstract
The embryonic and fetal development of the nuclear components and pathways of vagal sensorimotor circuits in the human has been studied using Nissl staining and carbocyanine dye tracing techniques. Eight fetal brains ranging from 8 to 28 weeks of development had DiI (1,1'-dioctadecyl-3,3,3',3' tetramethylindocarbocyanine perchlorate) inserted into either the thoracic vagus nerve at the level of the sternal angle (two specimens of 8 and 9 weeks of gestation) or into vagal rootlets at the surface of the medulla (at all other ages), while a further five were used for study of cytoarchitectural development. The first central labeling resulting from peripheral application of DiI to the thoracic vagus nerve was seen at 8 weeks. By 9 weeks, labeled bipolar cells at the ventricular surface around the sulcus limitans (sl) were seen after DiI application to the thoracic vagus nerve. Subnuclear organization as revealed by both Nissl staining and carbocyanine dye tracing was found to be advanced at a relatively early fetal age, with afferent segregation in the medial Sol apparent at 13 weeks and subnuclear organization of efferent magnocellular divisions of dorsal motor nucleus of vagus nerve noticeable at the same stage. The results of the present study also confirm that vagal afferents are distributed to the dorsomedial subnuclei of the human nucleus of the solitary tract, with particular concentrations of afferent axons in the gelatinosus subnucleus. These vagal afferents appeared to have a restricted zone of termination from quite early in development (13 weeks) suggesting that there is no initial exuberance in the termination field of vagal afferents in the developing human nucleus of the solitary tract. On the other hand, the first suggestion of afferents invading 10N from the medial Sol was not seen until 20 weeks and was not well developed until 24 weeks, suggesting that direct monosynaptic connections between the sensory and effector components of the vagal sensorimotor complex do not develop until this age.

Abstract
The architecture and musculotopic organization of the facial motor nucleus in the Cebus apella monkey (a New World primate) were investigated using histological techniques and a multiple labelling strategy, in which horseradish peroxidase-conjugated neuroanatomical tracers (CTB-HRP and WGA-HRP) and fluorescent tracers were injected into individual facial muscles. The facial motor nucleus was formed by multipolar motoneurons and had an ovoid shape, with its rostrocaudal axis measuring on average 1875 micro m. We divided the nucleus into four different subnuclei: medial, intermediate, dorsal and lateral. Retrograde labelling patterns revealed that individual muscles were innervated by longitudinal functional columns of motoneurons. The columns of the orbicularis oculi, zygomaticus, orbicularis oris, auricularis superior, buccinator and platysma muscles were located in the dorsal, intermediate, lateral, medial, lateral and intermediate subnuclei, respectively. However, the motoneuron columns of the levator labii superioris alaeque nasi muscle and frontalis muscle could not be associated with a specific subnucleus. The present results confirm previous studies regarding the musculotopic organization of the facial motor nucleus. However, we observed some particularities in terms of the relative size of each column in C. apella, which might be related to the functional and behavioral importance of each muscle in the particular context of this primate.

Abstract
The vagus, the 10th cranial nerve, contains pathways that contribute to the regulation of the internal viscera, including the heart. Vagal efferent fibers do not originate in a common brainstem structure. The Polyvagal Theory is introduced to explain the different functions of the two primary medullary source nuclei of the vagus: the nucleus ambiguus (NA) and the dorsal motor nucleus (DMNX). Although vagal pathways from both nuclei terminate on the sinoatrial node, it is argued that the fibers originating in NA are uniquely responsible for respiratory sinus arrhythmia (RSA). Divergent shifts in RSA and heart rate are explained by independent actions of DMNX and NA. The theory emphasizes a phylogenetic perspective and speculates that mammalian, but not reptilian, brainstem organization is characterized by a ventral vagal complex (including NA) related to processes associated with attention, motion, emotion, and communication. Various clinical disorders, such as sudden infant death syndrome and asthma, may be related to the competition between DMNX and NA.

Abstract
The mammalian upper respiratory tract (URT) serves as the common modality for aspects of respiration, deglutition, and vocalization. Although these actions are dependent on coordinated and specific neuromuscular control, little is known about the development of URT control centers. As such, this study investigated the occurrence of naturally occurring motoneuron cell death (MCD) in the nucleus ambiguus (NA) of a developmental series of rats. Standard histological techniques were used to count motoneurons in the ventrolateral brainstem where the mature NA is found. In addition, the neural tracer, fast DiI, was used to determine whether motoneurons were still migrating into the region of the NA during the period that cell counts were first taken. Furthermore, to elucidate the potential effect of inadvertently counting large interneurons on the assessment of motoneuron numbers, an antibody to gamma-aminobutyric acid (GABA) was used. The results of this study have, for the first time, demonstrated that MCD occurs in a URT-related motor nucleus. Approximately a 50% cell death was observed during the prenatal development of NA, with no further loss seen postnatally. The fast DiI studies showed that by embryonic day 17, NA was fully formed, suggesting that motoneuron migration from the basal plate was complete. In addition, use of the GABA antibody showed a lack of inhibitory interneurons within the NA. The finding of MCD in the NA helps define a critical period in the formation of URT neuromuscular control. As the course of MCD is modifiable by epigenetic signals, insult to the organism during this prenatal period may compromise future URT control.

Abstract
The differentiation of vagal motor neurons and their emerging central relationship with vagal sensory afferents was examined in fetal rats. To identify peripherally projecting sensory and motor neurons, 1,1'-dioctadecyl-3,3,3'3'-tetramethylindocarbocyanine perchlorate (DiI) was inserted into the proximal gut or cervical vagus nerve in fixed preparations. At embryonic day (E) 12, labeled vagal sensory neurons are present in the nodose ganglia and a few sensory axons project into the dorsolateral medulla. Central sensory processes become increasingly prevalent between E13 and E14 but remain restricted to the solitary tract. Vagal motor neurons are first labeled at E13, clustered within a region corresponding to the nucleus ambiguus (NA). Additional motor neurons appear to be migrating toward the NA from the germinal zone of the fourth ventricle. Motor neurons in the dorsal motor nucleus of the vagus (DMV) first project to the gut at E14 and have processes that remain in physical contact with the ventricular zone through E16. Sensory axons emerge from the solitary tract at E15 and project medially through the region of the nucleus of the solitary tract (NST) to end in the ventricular zone. A possible substrate for direct vagovagal, sensorimotor interaction appears at E16, when vagal sensory fibers arborize within the DMV and DMV dendrites extend into the NST. By E18, the vagal nuclei appear remarkably mature. These data suggest specific and discrete targeting of vagal sensory afferents and motor neuron dendrites in fetal rats and define an orderly sequence of developmental events that precedes the establishment of vagal sensorimotor circuits.
