Efferent Neurons and Vestibular Cross Talk in the Frog
Journal of Neurophysiology, 1997Myers, S. F., H. H. Salem, and J. A. Kaltenbach. Efferent neurons and vestibular cross talk in the frog. J. Neurophysiol. 77: 2061–2070, 1997. A galvanic stimulus (30- to 120-s, 0.3-mA constant current pulse) was used to depolarize the spike-generating region of horizontal and anterior canal afferent neurons.

Efferent neurons and specialization of abdominal segments in grasshoppers
The Journal of Comparative Neurology, 1999A specialized behavior, oviposition, is produced by the eighth and ninth abdominal segments of female grasshoppers. To begin to understand how these segments produce the behavior, which is not displayed by males or pregenital regions of the abdomen in females, the structure and function of efferent neurons in abdominal ganglia of both sexes were ...

Afferent and efferent connections of cat omnipause neurons
Experimental Brain Research, 1980Afferent and efferent connections of behaviorally identified omnipause neurons involved in saccadic eye movements were investigated electrophysiologically in cats anesthetized with ketamine hydrochloride. Pause cells were polysynaptically excited by electrical stimulation of the optic chiasm (mean latency = 8.3 ms), the visual cortex (mean latency = 7 ...

Localization and acetylcholinesterase content of vagal efferent neurons
Brain Research Bulletin, 1982The acetylcholinesterase (AChE) content of rat vagal efferent neurons was studied. Retrograde transport of horseradish peroxidase (HRP) by cut vagal axons provided a means for localizing efferent cell bodies; tissue sections were then processed for the simultaneous visualization of HRP and AChE. A dorsal vagal efferent column contained the dorsal motor

Induced modulations in autonomic efferent neuron activity
American Journal of Physiology-Legacy Content, 1963A study was made of the extent to which autonomic responses follow stimulation of the cerebellar cortex, somatic, and visceral afferent nerves. Activity of units in splanchnic and mesenteric nerves, in postganglionic fibers from the coeliac ganglion, and in vagus nerve branches to the stomach was recorded by microelectrodes.

CHROMATOLYSIS OF EFFERENT NEURONS
Archives of Neurology And Psychiatry, 1933Review of the literature relative to experimental peripheral injury to the nerves reveals many interesting results, interpretations and contentions, particularly concerning the effects produced on the body of the nerve cell. The subsequent changes in the neurocyte are exceedingly variable and present histologic pictures varying from one extreme to the ...

Efferent Connections of Brainstem Neurons
1990In this chapter we describe both immunohistochemically identified and nonidentified brainstem neuronal aggregates and their projections within and outside the brainstem core. We dissociate cholinergic from monoaminergic systems not only because of their chemical distinctness but also because of their dissimilar projection patterns to rostral brain ...

Periventricular efferent neurons in the optic tectum of rainbow trout
Journal of Comparative Neurology, 2006AbstractThe efferent connections and axonal and dendritic morphologies of periventricular neurons were examined in the optic tectum of rainbow trout to classify periventricular efferent neurons in salmonids. Among the target nuclei of tectal efferents, tracer injections to the following four structures labeled periventricular neurons: the area ...

Origin of the primary efferent neurons projecting to the prostate of the dog
Annals of Anatomy - Anatomischer Anzeiger, 2004The retrograde tracing technique of neuronal tracer Fast Blue was used to determine sources of origin of efferent nerve fibers supplying the prostate of the dog. After injection of Fast Blue into the canine prostate retrogradely labelled neurons were found in bilateral L3-S3 sympathetic chain ganglia, bilateral caudal mesenteric ganglion and in ...

Efferent projections of ProTRH neurons in the ventrolateral periaqueductal gray
Brain Research, 2001Our previous study has shown that prothyrotropin-releasing hormone (proTRH) gene expression is increased in the ventrolateral periaqueductal gray (PAG) neurons following precipitated morphine withdrawal and continues to be activated even 24 h after withdrawal.
