The pelvic ganglion (PG) provides both sympathetic and parasympathetic innervation to the genitalia and other pelvic structures. To determine whether neuronal activity; of the PG, as detected by Fos-like immunoreactivity (Fos-IR), is related to sexual stimulation, male and female rats were tested under a variety of conditions. In males, Fos-IR expression in(More)
The effects of polychlorinated biphenyls (PCBs) on development and reproduction are well documented. However, very little is known about the effects of PCBs on sexual behavior. In this study, we examined the effects of two commercial PCB mixtures, Aroclor 1221 (A1221) and Aroclor 1254 (A1254), on the development of female sexual behavior and of the(More)
After stereotactic lesions in the pallidum in 4 squirrel monkeys, electron microscopic material from the striatum was examined for anterograde and retrograde degenerative changes. In the experiment with pallidum internum lesion, only degenerated striatal fibers were observed, more than likely thalamostriatal fibers that pass through the site of the lesion.(More)
Social networking services (SNSs) have been garnering attention from society due to their recent rapid growth. This study examines whether SNS use can affect the relationship between the Big Five personality model and individual job satisfaction. Based on a sample of 1,452 workers in Korea, the results of this study indicate that the Big Five personality(More)
Stereotactic coagulations of intralaminar thalamic nuclei in 6 squirrel monkeys Saimiri sciureus produced dark degenerations only of type IV synapses in pallidum externum, according to the classification of Hassler and Chung often preserving the slightly asymmetric contact and subsynaptic densities. Other type IV boutons underwent semidark degeneration,(More)
The electron microscopic study of the neuronal structures of the pallidum externum (Pa.e) and internum (Pa.i) in squirrel monkey (Saimiri sciureus) has revealed in both segments a frequent large type of nerve cell and a rare small one, probably an interneuron. With respect to the small cells, only one axosomatic synapse inserts on the slender rim of(More)
