Cím:Projection from the nucleus isthmi to the visual and auditory centres in the frog, Rana esculenta / Akos Kulik, Clara Matesz
Dátum:1997
Megjegyzések:The lectin Phaseolus vulgaris leucoagglutinin was injected into the nucleus isthmi (NI) in order to study its anterograde and retrograde projections in the frog. The following areas of termination could be discerned in the brainstem: (1) Each of the five subnuclei of the torus semicircularis (TOS) received fibres from the NI. The projection was the most extensive on the three main subnuclei which disclosed also retrogradely labelled neurones on the side of injections. The subependymal subnuclei contained the least number of labelled fibres. (2) Both hemispheres of the optic tectum (TO) were supplied by fibres from the NI. Labelled fibres were more numerous on the side of injections, and preterminal and terminal fibres covered columnar-like areas in layers 8 and 9. Several retrogradely labelled neurones were found in layer 6. Relatively few labelled fibres were seen on the contralateral side. They formed patch-like areas of termination in layer 9. (3) The anterodorsal (AD) and anteroventral (AV) nuclei were reciprocally inter-connected with the NI. The fibre connections were less extensive on the contralateral side. In the rhombencephalon (4) the cochlear nucleus (CN) and (5) the superior olive (SO) were also reciprocally connected with the NI on both sides, but with much weaker projection on the side contralateral to injections. (6) Only a weak anterograde labelling was observed in the contralateral NI and in the ipsilateral reticular formation.

Cím:Sub-population of capsaicin sensitive primary afferent neurons in thoracic, lumbar and sacral dorsal root ganglion in young rats revealed by stimulated cobalt uptake / Kulik A., Polgár E., Matesz K., Kothalawala S., Szűcs P., Nagy I.
Dátum:1996
ISSN:0236-5383
Megjegyzések:The number of dorsal root ganglion (DRG) neurons, the relative number of capsaicin sensitive DRG cells and the diameter distribution of these neurons were investigated in the thoracic 11, lumbar 5 and sacral 1 DRG ganglia in young rats. The capsaicin sensitivity of DRG cells was shown by the stimulated cobalt uptake technique in in vitro conditions. Cobalt labelled and non-labelled neurons were counted using the dissector method. Our results show that the total number of DRG cells in the Th11, L5 and S1 segments (4200-6500 per ganglion) were not significantly different from each other and about 8% of these cells were capsaicin sensitive in the segments studied. These findings also show that the capsaicin sensitive DRG cells belong to the small diameter DRG cell population. Control experiments on neonatally capsaicin injected animals indicate that the capsaicin stimulated cobalt uptake provides selective and specific staining of capsaicin sensitive DRG neurons.

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:Connections of the torus semicircularis and oliva superior in the frog, Rana esculenta : a Phaseolus vulgaris leucoagglutinin labeling study / Clara Matesz, Á. Kulik
Dátum:1996
ISSN:0236-5383
Megjegyzések:The afferent and efferent connections of the frog principal nucleus (TP) of torus semicircularis (TOS) and superior olive (SO) were examined by employing the anterograde and retrograde transport patterns of Phaseolus vulgaris leucoagglutinin (PHA-L). After injecting the tracer into these nuclei it was found that the TP projected to the ipsilateral posterior and central thalamic nuclei, all subdivisions of the bilateral TDS and the ipsilateral nucleus isthmi (NI). In the rhombencephalon the projection was restricted mainly to the contralateral SO and the cochlear nucleus (CN). Retrogradely labeled cells were found in most of the areas that contained anterogradely labeled terminals. The termination areas of the SO fibers were similar to the projections of fibers of TP origin in the diencephalic and in the mesencephalic auditory centers. A strong projection was followed into the contralateral SO; the CNs received fibers at both sides. Caudally to the SO the reticular formation, the spinal nucleus of the trigeminal nerve, the solitary nucleus and the dorsal column nuclei were supplied by the fibers of the SO origin. Retrogradely labeled cells were found in the TOS, tegmental nuclei, solitary nucleus, dorsal column nuclei and in the spinal nucleus of the trigeminal nerve. Our results indicate that the frog auditory pathway is more complex at the level of the secondary and tertiary fiber projections than has been previously recognized.

Cím:Ascending and descending projections of the lateral vestibular nucleus in the frogRana esculenta / Matesz Clara, Kulik Ákos, Bácskai Timea
Dátum:2002
ISSN:0021-9967
Megjegyzések:The lectin Phaseolus vulgaris leucoagglutinin was injected into the frog lateral vestibular nucleus (LVN) to study its antero- and retrograde projections. The following new observations were made. 1) In the diencephalon, vestibular efferents innervate the thalamus in a manner similar to that of mammalian species. The projections show a preference for the anterior, central, and ventromedial thalamic nuclei. 2) In the mesencephalon, vestibular fibers terminate in the tegmental nuclei and the nucleus of medial longitudinal fascicle. 3) In the rhombencephalon, commissural and internuclear projections interconnect the vestibular nuclei. Some of the termination areas in the reticular formation can be homologized with the mammalian inferior olive and the nucleus prepositus hypoglossi. Another part of the vestibuloreticular projection may transmit vestibular impulses toward the vegetative centers of the brainstem. A relatively weak projection is detected in the spinal nucleus of the trigeminal nerve, dorsal column nuclei, and nucleus of the solitary tract. 4) In the spinal cord, vestibular terminals are most numerous in the ipsilateral ventral horn and in the triangular area of the dorsal horn. 5) The coincidence of retrogradely labeled cells with vestibular receptive areas suggests reciprocal interconnections between these structures and the LVN. 6) In seven places, the LVN projections overlap the receptive areas of proprioceptive fibers, suggesting a convergence of sensory modalities involved in the sense of balance.

Dátum:2002
ISSN:0361-9230
Megjegyzések:The efferent connections of the superior, medial, lateral, and descending vestibular nuclei were studied with anterograde tracing methods in rats. The following areas of termination could be discerned: (1) In the diencephalon, labeled terminals were detected in the thalamus. (2) In the mesencephalon, the red nucleus and motor nuclei involved in eye movements were richly supplied by the vestibular nuclei. (3) In the rhombencephalon, extensive intrinsic connections of all vestibular nuclei were demonstrated. Strong commissural connections were found among the medial, superior, and descending vestibular nuclei. The inferior olive received labeled fibers exclusively from the lateral vestibular nuclei. Individual differences were demonstrated in the termination areas in the reticular formation. (4) In the spinal cord, most of the descending vestibular fibers were found in the ipsilateral anterior funiculus.
