We have investigated with light and electron microscope immunocytochemistry the aminergic and peptidergic innervation of Onuf's nucleus in adult baboons. This nucleus, located in the ventrolateral part of the sacral spinal cord (S2 and S3), is considered to control urethral and anal sphincters and penile muscles. By comparison of intact and transected spinal cords, we have found that serotoninergic innervation has two origins: first, supraspinal, innervating the whole nucleus, with a possible… 

Immunohistochemical examination of intraspinal serotonin neurons and fibers in the chicken lumbar spinal cord and coexistence with Leu-enkephalin

Intraspinal serotonin-positive cells and fibers were examined in the chicken lumbar spinal cord following removal of descending serotonin fibers by spinal transection and co-localization of Leu-enkephalin immunoreactivity was examined using a double immunofluorescence labeling technique.

Distribution of dopamine immunoreactivity in the rat, cat, and monkey spinal cord

It is concluded that DA is widely distributed within the spinal cord, with few differences between species, emphasizing that DA plays an important role as one of the monoamines that influences sensory input as well as autonomic and motor output at the spinal level.

Serotonin 5‐HT2A and 5‐HT5A receptors are expressed by different motoneuron populations in rat Onuf's nucleus

Comparisons show a preferential localization of 5‐HT2A and 5‐ HT5A receptors to motoneurons controlling the striated muscles located at the penile crus and sphincter muscles, respectively, suggesting a specific serotoninergic control on different pelvic functions.

Anatomical study of serotonergic innervation and 5-HT1A receptor in the human spinal cord

A preliminary mapping of serotonergic processes and serotonin-lA (5-HT1A) receptors in thoracic and lumbar segments of the human spinal cord is performed and pave the way for local specific therapies involving cellular and/or pharmacological tools targeting theserotonergic system.

Catecholaminergic projections onto spinal neurons destined to the pelvis including the penis in rat

In adult male rats, the catecholaminergic innervation of spinal neurons controlling lower urogenital tissues and regulating penile erection is evidenced by combining retrograde tracing techniques and immunohistochemistry against synthetic enzymes of noradrenaline and adrenaline.

Expression Pattern of 5-HT (Serotonin) Receptors during Normal Development of the Human Spinal Cord and Ganglia and in Fetus with Cervical Spina Bifida

A human-species specific sr expression pattern is indicated, and the importance of sr1 in neuronal differentiation, and sr2 and sr3 in the control of the roof plate morphogenesis in normal and disturbed development is indicated.



Immunohistochemical distribution of substance P, serotonin, and methionine enkephalin in sexually dimorphic nuclei of the rat lumbar spinal cord

The division of this motor column into a medial part composed of ischiocavernosus motoneurons surrounded by enkephalin‐ and serotonin‐like immunoreactivity and a lateral part that contains neurons that project to the sphincter urethrae muscle is suggested.

A developmental study of substance‐P, somatostatin, enkephalin, and serotonin immunoreactive elements in the spinal cord of the North American opossum

Evidence for SOM immunoreactivity was found within all areas of the spinal gray matter expected from studies of the adult opossum, and demonstration of SOM‐, ENK‐, and 5‐HT‐like immunoreactivities in neuronal somata ofThe spinal cord was age dependent.

The primate serotonergic system: a review of human and animal studies and a report on Macaca fascicularis.

The serotonin-producing neurons of M fascicularis were analyzed, using immunocytochemistry, radioautography, and measurements of synaptosomal serotonin reuptake and supernatant tryptophan hydroxylase activity to provide evidence for the presence of serotonin fibers in all cortical and subcortical regions.
