Axons of sacral preganglionic neurons in the cat: II. Axon collaterals
The data lead to the conclusion that sacral preganglionic neurons have multiple functions within the spinal cord in addition to serving their target organ.
Identification of penile inputs to the rat gracile nucleus.
Results indicate that neurons in the gracile nucleus are likely part of the pathway that provides low-threshold penile inputs to MRF, a region known to play an important role in mating processes.
Localization of neurons projecting into the extrinsic penile smooth musculature of the pig: an experimental study on the retractor penis muscle.
The aim of this study was to locate in male pigs the sensory and autonomic ganglia innervating the retractor penis muscle (RPM), which was taken as an experimental model of the genital smooth
The basic neural circuitry for sexual behavior
The results show that the distribution pattern of anterogradely labeled fibers in the lumbosacral cord matched precisely the location of certain motoneuronal cell groups.
Excitatory synaptic currents in lumbosacral parasympathetic preganglionic neurons evoked by stimulation of the dorsal commissure.
Results indicate that PGN receive monosynaptic and polysynaptic glutamatergic excitatory inputs from neurons and/or axonal pathways in the DCM, and type 1 EPSCs in some PGN responded in an all-or-none manner and presumably represented unitary synaptic responses; whereas Type 2 EPSCs always exhibited a graded stimulus intensity-response relationship.
Peripheral ganglia supplying the genital smooth musculature in the female pig: an experimental study
The aim of the present study was to locate the sensory and autonomic ganglia innervating the female genital musculature in pigs and labelled cells were found in ipsilateral dorsal root ganglia Sl–S4, in bilateral sympathetic paravertebral ganglia and in the left and right caudal mesenteric ganglion.

A clear role of genital afferents in modulating the micturition reflex is demonstrated and the DNP is suggested as a potential target for functional restoration of bladder control using electrical stimulation.
Neural control of the lower urinary tract.
This article summarizes anatomical, neurophysiological, pharmacological, and brain imaging studies in humans and animals that have provided insights into the neural circuitry and neurotransmitter
Excitability changes in sacral afferents innervating the urethra, perineum and hindlimb skin of the cat during micturition
It is concluded that control of transmission from urethral afferents by the micturition circuitry is different to that by sensory transmission from hindlimb and perineal regions during mictsurition.


Organization of afferent and efferent pathways in the pudendal nerve of the female cat
Application of horseradish peroxidase to the pudendal nerve in the female cat labelled lumbosacral afferent and efferent neurons and their processes and its relationship with sacral autonomic pathways is discussed.
The distribution of visceral primary afferents from the pelvic nerve to Lissauer's tract and the spinal gray matter and its relationship to the sacral parasympathetic nucleus
The widespread rostrocaudal extent of the pelvic primary afferent projection is consistent with the necessity for the integration of somatic and autonomatic elements from various levels of the lumbo‐sacral‐coccygeal spinal cord in the performance of pelvic visceral functions.
Physiological characterization of spinohypothalamic tract neurons in the lumbar enlargement of rats.
Findings indicate that relatively precise information about the location of innocuous and noxious stimuli is conveyed directly to the hypothalamus by SHT neurons.
Characterization of neuronal responses to noxious visceral and somatic stimuli in the medial lumbosacral spinal cord of the rat.
The cutaneous receptive fields, long ascending projections, and responses to colorectal distension (20-100 mmHg) and tail movement of 252 neurons in spinal segments L6-S1 were characterized in
Visceral and somatic afferent convergence onto neurons near the central canal in the sacral spinal cord of the cat.
In the sacral spinal cord many cells near the CC receive primary afferent inputs converging from a wide range of receptor types in somatic and visceral structures, capable of integrating afferent information from somatic structures on both sides of the body with information originating in pelvic viscera and midline regions such as the genitals.
Origin and central projections of rat dorsal penile nerve: Possible direct projection to autonomic and somatic neurons by primary afferents of nonmuscle origin
Cell number, size, and somatotopic arrangement within the spinal ganglia of the cells of origin of the rat dorsal penile nerve (DPN), and their spinal cord projections, were studied by loading the
Central distribution of afferent pathways from the uterus of the cat
Ovariectomy did not change significantly the number, sizes, or segmental distribution of uterine afferent neurons, but double dye labeling experiments indicate that, a small percentage of lumbar neurons innervating the uterusine cervix also innervate the uterine horn.
The spinothalamic tract: An examination of the cells of origin of the dorsolateral and ventral spinothalamic pathways in cats
The locations of Spinothalamic neurons and the funicular trajectories of their axons were studied in cats by retrograde transport of horseradish peroxidase (HRP) to confirm the uniformity of the injection sites, transport and tissue processing.
