Example Sentences:
(1) In epileptic hippocampi, (n = 21) reactive synaptogenesis of mossy fibers into the inner molecular layer of the granule cell dendrites was demonstrated at the light microscopic and electron microscopic levels.
(2) The developmental pattern of hippocampal mossy fiber (dentate granule cell axon) innervation to the pyramidal cell layer was examined with anterograde transport methods.
(3) The decrease in cerebellar cGMP content elicited by haloperidol can be differentiated from that elicited by diazepam; perhaps haloperidol reduces the mossy fiber input to the cerebellum.
(4) The role of intracellular calcium in an APV-insensitive form of long-term potentiation (LTP) has been studied at the hippocampal mossy fiber synapse.
(5) A study of seizure activity and neuronal cell death produced by intracerebroventricular kainic acid had suggested that seizures conveyed by the hippocampal mossy fibers are more damaging to CA3 pyramidal cells than seizures conveyed by other pathways.
(6) These results demonstrate that serotonergic fiber input from DR can suppress the efficacy of mossy and climbing fiber synaptic action on PC, or decrease the responsiveness of PC itself to afferent synaptic action.
(7) In the rat, neonatal irradiation produces a destruction of dentate granule cells and prevents the development of the mossy fibre-CA3 pyramidal cell synapse.
(8) These lesions destroyed mossy terminals and their parent axons and thus initiated a retrograde reaction in basilar pontine projection neurons which manifested itself in the form of morphologic alterations observed in somata, dendrites, and a class of axonal boutons.
(9) Short-term changes in synaptic efficacy were studied at the mossy fiber (MF) to CA3 (MF-CA3) synapse in the in vitro hippocampus.
(10) To facilitate improvement of investigations on the distribution of mossy fibers in the hippocampal formation, a method is described using Timm's stained preparations after methacrylate embedding with the hydrophilic resin, Quetol 523M.
(11) The quantitative and topographical differences in the origin of mossy fibers suggest that these lobules may subserve slightly different functions.
(12) A highly positive correlation was found, in both species, between the synaptic surface and the number of agranular vesicles per unit volume of mossy fiber endings, while no correlation was found between the synaptic surface and numerical densities of coated and dense core vesicles.
(13) The distribution of mossy fiber terminals originating from the lower thoracic-higher lumbar spinal cord was compared to the distribution of zebrin I bands.
(14) Taurine localization to cerebellar mossy fibers and to fibers in the molecular layer of the dentate gyrus may be more consistent with a proposed neuromodulator role of taurine.
(15) The orthograde and retrograde HRP studies suggested that the mossy fibre response is mediated by the pontine grey whereas the climbing fibre response is conveyed indirectly to the inferior olive which sends the climbing fibres to the cerebellar cortex.
(16) The effect of dietary zinc deficiency on the mossy fiber zinc content of the rat hippocampus was investigated using PIXE (Particle Induced X-Ray Emission) spectroscopy.
(17) These results are consistent with the hypothesis that the floccular H-zone Purkinje cells adaptively control the optokinetic eye movement through modification of the visual mossy fiber responsiveness under the influence of the retinal error signals conveyed by the visual climbing pathway.
(18) The responses of Purkinje cells and presumed mossy fibers to natural stimulation of the horizontal semicircular canals were recorded in the nodulus and uvula of rabbit vestibulocerebellum.
(19) Feeding a zinc-deficient diet for 28 days did not cause a decrease in the mossy fiber zinc level, however, feeding the zinc-deficient diet for 90 days reduced the maximum mossy fiber zinc level by about 30%.
(20) The electron-microscopic examination of hippocampal tissues from rats that had been perfused with fixative during the seizure revealed that the large dense-core vesicles increased in number and accumulated on the presynaptic membranes of mossy fiber boutons; some of these vesicles appeared to be fused with the membranes, and omega-shaped exocytotic profiles were frequently seen.
