Cím:Ascending and descending projections of the lateral vestibular nucleus in the rat / Tímea Bácskai, G. Székely, Clara Matesz
Dátum:2002
ISSN:0236-5383
Megjegyzések:The tracer neurobiotin was injected into the lateral vestibular nucleus in rat and the efferent fiber connections of the nucleus were studied. The labeled fibers reached the diencephalon rostrally and the sacral segments of the spinal cord caudally. In the diencephalon, the ventral posteromedial and the gustatory nuclei received the most numerous labeled fibers. In the mesencephalon, the inferior colliculus, the interstitial nucleus of Cajal, the nucleus of Darkschewitch, the periaqueductal gray matter and the red nucleus received large numbers of labeled fibers. In the rhombencephalon, commissural and internuclear connections originated from the lateral vestibular nucleus to all other vestibular nuclei. The medioventral (motor) part of the reticular formation was richly supplied, whereas fewer fibers were seen in the lateral (vegetative) part. In the spinal cord, the descending fibers were densely packed in the anterior funiculus and in the ventral part of the lateral funiculus. Collaterals invaded the entire gray matter from lamina IX up to lamina III; the fibers and terminals were most numerous in laminae VII and VIII. Collateral projections were rich in the cervical and lumbosacral segments, whereas they were relatively poor in the thoracic segments of the spinal cord. It was concluded that the fiber projection in the rostral direction was primarily aimed at sensory-motor centers; in the rhombencephalon and spinal cord, fibers projected onto structures subserving various motor functions.

Cím:Peripheral reinnervation patterns and dorsal root ganglion topography in skin-grafted frogs : a behavioral and histological examination / Baker R. E., Matesz K., Corner M. A., Székely G.
Dátum:1981
ISSN:0378-5866
Megjegyzések:Behavioral responses to mechanical stimulation of the skin were observed in unoperated, 180 degrees skin-rotated and sham-grafted Rana pipiens frogs before and after crushing various cutaneous nerve bundles. In the two control groups, wiping responses directed towards the animal's dorsum were mediated solely via dorsomedial (DM) and dorsolateral (DL) nerve trunks. In skin-rotated frogs, DM and DL nerve trunks were responsible for almost all of the misdirected responses elicited from dorsal cutaneous areas. Six frogs (2 sham- and 4 skin-rotated) possessed some areas of plical skin from which responses could only have been mediated via more ventrally located nerve trunks. However, such dorsal expansions of ventral receptive fields never included the midline skin areas from which misdirected responses had been elicited in the intact animal. The topographic arrangement of cells within the DRG appears to be weakly polarized in cobalt-stained sections, but with large individual variations in size and observed number of neuronal profiles. For the skin-rotated group the ratio of cobalt-filled profiles in the dorsal as compared with the ventral half of the ganglion was 1.6, which did not differ significantly from the control value of 1.9. Taken as a whole, the results of the present study indicate that selective (re)innervation of displaced skin by the original nerve fibers cannot explain the origin of misdirected responses in Rana pipiens.

Cím:Quantitative morphological analysis of the motoneurons innervating muscles involved in tongue movements of the frogRana esculenta / Birinyi András, Székely György, Csapó Krisztina, Matesz Klára
Dátum:2004
ISSN:0021-9967
Megjegyzések:We give an account of an effort to make quantitative morphological distinctions between motoneurons of the frog innervating functionally different groups of muscles involved in the movements of the tongue. The protractor, retractor, and inner muscles of the tongue were considered on the basis of their major action during the prey-catching behavior of the frog. Motoneurons were selectively labeled with cobalt lysin through the nerves of the individual muscles, and dendritic trees of successfully labeled neurons were reconstructed. Each motoneuron was characterized by 15 quantitative morphological parameters describing the size of the soma and dendritic tree and 12 orientation variables related to the shape and orientation of the dendritic field. The variables were subjected to multivariate discriminant analysis to find correlations between form and function of these motoneurons. According to the morphological parameters, the motoneurons were classified into three functionally different groups weighted by the shape of the perikaryon, mean diameter of stem dendrites, and mean length of dendritic segments. The most important orientation variables in the separation of three groups were the ellipses describing the shape of dendritic arborization in the horizontal, frontal, and sagittal planes of the brainstem. These findings indicate that characteristic geometry of the dendritic tree may have a preference for one array of fibers over another.

Cím:Mesencephalic projections of the cochlear nucleus in the frog, Rana esculenta / Kulik A., Matesz C., Székely G.
Dátum:1994
ISSN:0236-5383
Megjegyzések:The lectin Phaseolus vulgaris leucoagglutinin was injected into chochlear nucleus in order to study the trajectory and projections of the auditory pathway in the frog. A strong contralateral and a weak ipsilateral fiber bundle representing the lemniscus lateralis could be followed to the torus semicircularis. The following areas of termination could be discerned in the mesencephalon: (1) Each of the five subnuclei of the torus semicircularis received fibers from the cochlear nucleus, the largest number of fibers terminated in the principal nucleus. (2) Nuclei of the mesencephalic tegmentum were supplied by fibers from the cochlear nucleus on both sides. (3) The nucleus isthmi was innervated by a few small caliber fibers, and (4) the nucleus visceralis secundarius was richly supplied by large caliber fibers. Two ill-defined neuron groups in the mesencephalic tegmentum, the nucleus reticularis isthmi (5) and (6) the nucleus profundus mesencaphali were conspicuously outlined by the terminals of auditory fibers. Their positions suggested homology to the mammalian nucleus of the lemniscus lateralis. (7) A few fibers and boutons were labelled in the fifth and sixth layers of the optic tectum. Retrogradely labelled cells were found in the nucleus laminaris of the torus semicircularis and in the nuclei of mesencephalic tegmentum. Our results indicate that the frog auditory pathway is more complex at the level of the secondary fiber projections than has been previously recognized. The retrogradely labelled neurons suggest a descending control of the cochlear nucleus from higher structures of the auditory pathway.

Cím:Fine structure of dorsal root terminals in the dorsal horn of the frog spinal cord / G. Lévai, C. Matesz, G. Székely
Dátum:1982
ISSN:0001-5288
Megjegyzések:Dorsal root fibers were labelled with cobalt and their terminals were identified in an oval-shaped area and in its lateral extension of the dorsal horn. These areas receive mainly cutaneous afferents. A number of labelled terminals exhibited either an electron lucent and swollen, or an electron dense and shrunken form of degeneration. The majority of the labelled terminals could be classified into three groups. Type A terminals were small, less than 2 microns in diameter, and lightly stained. Type B terminals were larger and neurofilaments and an electron dense material resulted in a dark staining of the bouton. Type C terminals contained medium size granulated vesicles. The type A and type B terminals were frequently found in postsynaptic positions. The presynaptic profiles contained spheric or elliptic vesicles, or they exhibited the structural characters of presynaptic dendrites. Preterminal dorsal root fibers, identified on account of their cobalt label, were also found in postsynaptic positions to the same kinds of presynaptic profiles. It is concluded that cobalt labelling is sufficiently selective for a reliable identification of dorsal root terminals. No correlation was found between the different forms of degeneration and the different types of terminal boutons. The possible functional significance of the postsynaptic relation of dorsal root fibers and terminals to a variety of presynaptic profiles is discussed.

Cím:Organization of the ambiguus nucleus in the frog (Rana esculenta) / Clara Matesz, George Székely
Dátum:1996
ISSN:0021-9967
Megjegyzések:The common root of the glossopharyngeal, vagal, and accessory nerves and the individual branches of the vagus complex were labeled with cobalt, and the organization of the ambiguus nucleus was studied. The cell column labeled through the common root extended from the upper part of the medulla to the rostral spinal cord over a distance of about 3,500 microns. The labeling of individual branches revealed four subdivisions. 1) The pharyngomotor subdivision occupied the rostral 800 microns of the cell column. It gave origin to the innervation of the pharyngeal muscles. 2) The visceromotor subdivision, consisting of small and medium-sized cells labeled by way of the visceral branches of the vagus, was found in the rostrocaudal extent of the medulla. 3) the laryngomotor subdivision extended in the obex region over a distance of more than 1,000 microns. It supplied the sphincter muscles of the larynx. The dilator laryngeal muscle was represented in the rostral part of the visceromotor subdivision. 4) The accessory nerve subdivision was located in the lower medulla and the rostral spinal cord. From the results, the following conclusions are drawn. 1) The basic organization of the frog ambiguus nucleus is comparable to that of the rat, differences in nuclear organization reflecting differences in peripheral structures. 2) The cytoarchitectonic structure of the four subdivisions innervating different peripheral targets characteristically differ from each other. 3) On the basis of its characteristic neuronal morphology, the accessory nerve nucleus is regarded as an independent structure.

Cím:The dorsomedial nuclear group of cranial nerve in the frog / Clara Matesz, G. Székely
Dátum:1977
ISSN:0001-5288
Megjegyzések:The dorsomedial motor nuclei were demonstrated by the cobalt-labeling technique applied to the so-called somatic motor cranial nerves. The motoneurons constituting these nuclei are oval-shaped and smaller than the motoneurons in the ventrolateral motor nuclei. They give rise to ventral and dorsal dendrite groups which have extensive arborization areas. A dorsolateral cell group in the rostral three quarters of the oculomotorius nucleus innervates ipsilateral eye muscles (m.obl.inf., m.rect.inf., m.rect.med.) and a ventromedial cell group innervates the contralateral m. rectus superior. Ipsilateral axons originate from ventral dendrites, contralateral axons emerge from the medial aspect of cell bodies, or from dorsal dendrites, and form a "knee" as they turn around the nucleus on their way to join the ipsilateral axons. A few labeled small cells found dorsal and lateral to the main nucleus in the central gray matter are regarded as representing the nucleus of Edinger-Westphal. The trochlearis nucleus is continuous with the ventromedial cell group of the oculomotorius nucleus. The axons originate in dorsal dendrites, run dorsally along the border of the gray matter and pierce the velum medullare on the contralateral side. A compact dendritic bundle of oculomotorius neurons traverse the nucleus, and side branches appear to be in close apposition to the trochlearis neurons. A dorsomedial and a ventrolateral cell group becomes labeled via the abducens nerve. The former supplies the m. rectus lateralis, while the latter corresponds to the accessorius abducens nucleus which innervates the mm. rectractores. Neurons in this latter nucleus are large and multipolar, resembling the neurons in the ventrolateral motor nuclei. Their axons originate from dorsal dendrites and form a "knee" around the dorsomedial aspect of the abducens nucleus. Cobalt applied to the hypoglossus nerve reaches a dorsomedial cell group (the nucleus proper), spinal motoneurons and sympathetic preganglionic neurons. Of the dorsomedial motor cells, the hypoglossus neurons are the largest, and a branch of their ventral dendrites terminates on the contralateral side. Some functional and developmental biological aspects of the morphological findings, such as the crossing axons and the peculiar morphology of the accessory abducens nucleus, are discussed.

Cím:The motor nuclei of the glossopharyngeal-vagal and the accessorius nerves in the rat / Clara Matesz, G. Székely
Dátum:1983
ISSN:0236-5383
Megjegyzések:Retrograde cobalt labeling was performed by incubating the rootlets of cranial nerves IX, X and XI, or the central stumps of the same nerves, in a cobaltic lysine complex solution, and the distribution of efferent neurons sending their axons into these nerves was investigated in serial sections of the medulla and the cervical spinal cord in young rats. The following neuron groups were identified. The inferior salivatory nucleus lies in the dorsal part of the tegmentum at the rostral part of facial nucleus. It consists of a group of medium-sized and a group of small neurons. Their axons make a hair-pin loop at the midline and join the glossopharyngeal nerve. The dorsal motor nucleus of the vagus situates in the dorsomedial part of the tegmentum. Its rostral tip coincides with the first appearance of sensory fibres of the glossopharyngeal nerve, the caudal end extends into the pyramidal decussation. The constituting cells have globular or fusiform perikarya and they are the smallest known efferent neurons. The ambiguous nucleus is in the ventrolateral part of the tegmentum. The rostral tip lies dorsal to the facial nucleus, and the caudal tip extends to the level of the pyramidal decussation. The rostral one third of the ambiguous nucleus is composed of tightly-packed medium sized neurons, while larger neurons are arranged more diffusely in the caudal two thirds. The long dendrites are predominantly oriented in the dorsoventral direction. The dorsally-oriented axons take a ventral bend anywhere between the ambiguous nucleus and dorsal motor nucleus of the vagus. The motoneurons of the accessorius nerve are arranged in a medial, a lateral and a weak ventral cell column. The medial column begins at the caudal aspect of the pyramidal decussation and terminates in C2 spinal cord segment. The lateral and ventral columns begin in C2 segment and extend into C6 segment. The neurons have large polygonal perikarya and characteristic cross-shaped dendritic arborizations. The axons follow a dorsally-arched pathway between the ventral and dorsal horns. The accessorius motoneurons have no positional relation to any of the vagal efferent neurons. It is concluded that the topography and neuronal morphology of accessorius motoneurons do not warrant the designation of a bulbar accessorius nucleus and a bulbar accessorius nerve.

Cím:Organization of the motor centres for the innervation of different muscles of the tongue : a neuromorphological study in the frog / C. Matesz, I. Schmidt, L. Szabó, A. Birinyi, G. Székely
Dátum:1999
Megjegyzések:Cobalt labelling studies on the localization and morphology of the frog's hypoglossal nucleus have revealed three subnuclei. The dorsomedial subnucleus innervates the geniohyoid, hyoglossus, genioglossus and the intrinsic tongue muscles. The ventrolateral subnucleus supplies the sternohyoid, geniohyoid, omohyoid and intrinsic tongue muscles. The intermediate subnucleus innervates the omohyoid, geniohyoid and intrinsic tongue muscles. Neurons innervating protractor, retractor and intrinsic tongue muscles differ in their soma surface area and in their dendritic arborization pattern. It is concluded that there exists a musculotopic organization in the frog's hypoglossal nucleus and that motoneurons subserving different function in tongue movements disclose characteristic morphological differences.
