▪ Abstract The development of the sympathetic nervous system can be divided into three
overlapping stages. First, the precursors of sympathetic neurons arise from undifferentiated …

Introduction Despite the fact that important advances in research on neuroendocrine
neoplasms (NENs) have been made, consistent data about their pathogenetic mechanism …

Neuroendocrine tumors of the thymus (TNET) are exceedingly rare neoplasms. Their
histomorphology is identical to neuroendocrine tumors elsewhere in the body (in particular …

The nature of neural plasticity and the factors that influence it vary throughout life. Adult
neurons undergo extensive and continual adaptation in response to demands that are quite …

Systematic studies of the autonomic nervous system of human subjects and development of
well-defined animal models have begun to substantially improve our understanding of the …

Descriptive studies have delineated a developmental change in neurotransmitter phenotype
from noradrenergic to cholinergic in the sympathetic innervation of sweat glands in rodent …

The capacity of self-organized systems to adapt is embodied in the functional organization of
intrinsic control mechanisms. Evolution in functional complexity of heart rate variability …

Many cholinergic parasympathetic and enteric neurons require neurturin signaling through
GDNF family receptor GFRα2 for target innervation. Since a distinct minority of sympathetic …

Target-derived factors modulate many aspects of peripheral neuron development including
neuronal growth, survival, and maturation. Less is known about how initial target contact …

Functional integrity of the regenerated tissues requires not only structural integrity but also
vascularization and innervation. We previously demonstrated that the three-dimensional …
