Organization of efferent peripheral synapses at mechanosensory neurons in spiders

The Journal of Comparative Neurology, 2000
The mechanosensory neurons of arachnids receive diverse synaptic inputs in the periphery. The function of most of these synapses, however, is unknown. We have carried out detailed electron microscopic investigations of the peripheral synapses at sensory neurons in the compound slit sense organ VS-3 of the spider Cupiennius salei.

Efferent neurons to the macula lagena in the embryonic chick

Hearing Research, 1995
The lipophilic dye, DiI, was placed into the macula lagena of paraformaldehyde-fixed embryonic chicks. Retrogradely labeled cells were found bilaterally in the pontine reticular formation (RF) between the dorsal facial nucleus and the abducens nerve root.

Anatomy and Neurophysiology of the Subthalamic Efferent Neurons

1984
The subthalamic nucleus, part of the so-called basal ganglia, is a well-defined nucleus surroxmded by fibers, the internal capsule, the ansa and fasciculus lenticularis, and in the rat the cerebral peduncle (Fig. 1). In primates its vascular or experimental lesioning gives rise to a specific motor syndrome characterized by involuntary, large, violent ...

The Localization of Vestibular Efferent Neurons in the Kitten with Horseradish Peroxidase

Acta Oto-Laryngologica, 1974
The location of efferent vestibular neurons in the brainstem of newborn kittens was determined by means of horseradish peroxidase used as a tracer of retrograde protein transport. Two to three milligrams of horseradish peroxidase were injected into the vestibule of 8 kittens.

The sensory-efferent function of capsaicin-sensitive sensory neurons

General Pharmacology: The Vascular System, 1988
Capsaicin-sensitive sensory neurons convey to the central nervous system signals (chemical and physical) arising from viscera and the skin which activate a variety of visceromotor and neuroendocrine reflexes integrated at various levels (intramurally in peripheral organs, at level of prevertebral ganglia, spinal and supraspinal level). Much evidence is

Ultrastructure of Contralaterally Projecting Vestibular Efferent Neurons in the Cat

Archives of Otolaryngology - Head and Neck Surgery, 1988
Numerous reports have demonstrated that primary vestibular afferent axons terminate in the vicinity of centrally located vestibular efferent (VE) neurons. The goal of this study was to morphologically demonstrate contact of primary vestibular afferents directly on the soma of contralaterally projecting VE neurons, as well as develop a quantitative ...

Morphology and immunohistochemistry of efferent neurons of the goldfish corpus cerebelli

Journal of Comparative Neurology, 2005
AbstractIn teleosts, cerebellar efferent neurons, known as eurydendroid cells, are dispersed within the cerebellar cortex rather than coalescing into deep cerebellar nuclei. To clarify their morphology, eurydendroid cells were labeled retrogradely by biotinylated dextran amine injection into the base of the corpus cerebelli.

Location of efferent and afferent neurons innervating the ovary in the hen

Journal of the Autonomic Nervous System, 1994
Efferent and afferent neurons were labeled by injections of horseradish peroxidase into the ovary of the hen. Sympathetic postganglionic neurons were located in the paravertebral ganglia T2-LS2 (28% of total number of labeled neurons) and prevertebral ganglia (36%).

Paraventricular nucleus efferents influence area postrema neurons

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1996
Extracellular single-unit recordings were obtained from area postrema neurons (AP), and peristimulus histograms were used to determine the effects of paraventricular nucleus (PVN) stimulation on these cells from anesthetized Sprague-Dawley rats. Of 91 AP cells tested, 30.8% responded to PVN stimulation with a short-latency (28.2 +/- 3.3 ms, mean ...

Neurons of the median neuroblast lineage of the grasshopper: A population study of the efferent DUM neurons

Journal of Comparative Neurology, 1995
AbstractA group of lineally related neurons in the grasshopper was studied to determine the number of efferent neurons in the group and their morphological types. The neurons arise from the median neuroblast of the third thoracic neuromere and comprise what is commonly known as the DUM or dorsal unpaired median group.
