Cerebellar nuclei neurons integrate sensorimotor information and form the final output of the cerebellum, projecting to premotor brainstem targets. This implies that, in contrast to specialized neurons and interneurons in cortical regions, neurons within the nuclei encode and integrate complex information that is most likely reflected in a large variation of intrinsic membrane properties and in...
Local field-potentials (LFPs) are generated by neuronal ensembles and contain information about the activity of single neurons. Here, the LFPs of the cerebellar granular layer and their changes during long-term synaptic plasticity (LTP and LTD) were recorded in response to punctate facial stimulation in the rat in vivo. The LFP comprised a trigeminal (T) and a cortical (C) wave. T and C, which ...
In spite of the existing reports on behavioural and biochemical changes related to the cerebellum due to noise stress, not much is known about the effect of noise stress on the neuronal changes in the cerebellum. The present study aims at investigating the effects from one week noise exposure on granule cell number and Purkinje cell volume within the neonate rat cerebellum.15-day-old male Wista...
Vesicular glutamate transporter 1 (VGluT1) is one of the best markers for glutamatergic neurons, because it accumulates transmitter glutamate into synaptic vesicles. Differentiation-associated Na(+)-dependent inorganic phosphate cotransporter (DNPI) shows 82% amino acid identity to VGluT1, and is another candidate for vesicular glutamate transporters. Here, we report the immunocytochemical loca...
Although the basic morphological characteristics of neurons in the cerebellar cortex have been documented in several species, virtually nothing is known about the quantitative morphological characteristics of these neurons across different taxa. To that end, the present study investigated cerebellar neuronal morphology among eight different, large-brained mammalian species comprising a broad ph...
GABAergic projection neurons in the cerebellar nuclei (CN) innervate the inferior olive (IO) that in turn is the source of climbing fibers targeting Purkinje neurons in the cerebellar cortex. Anatomical evidence suggests that CN synapses modulate electrical coupling between IO neurons. In vivo studies indicate that they are also involved in controlling synchrony and rhythmicity of IO neurons. H...
The functional partitioning of the cerebellar cortex depends on the projection patterns of its afferent and efferent neurons. However, the entire morphology of individual projection neurons has been demonstrated in only a few classes of neurons in the vertebrate CNS. To investigate the contribution of the projection pattern of individual olivocerebellar axons to the cerebellar functional compar...
the hippocampus showing the granular cell layer of the dentate gyrus (arrows) revealed by DTI contrasts at 160 Hz, which is not discernible at 0 Hz. Corresponding nissl-stained sections indicating the granular cell layer of the dentate gyrus (DG_gr) are shown for anatomical comparison. Bottom panel) Mean ADC in the DG_gr and a region within the CA1 subfield of the hippocampus plotted as a funct...
Infection of newborn rats with Borna disease virus (BDV) leads to persistence in the absence of overt signs of inflammation. BDV persistence, however, causes cerebellar hypoplasia and hippocampal dentate gyrus neuronal cell loss, which are accompanied by diverse neurobehavioral abnormalities. Neurotrophins and their receptors play important roles in the differentiation and survival of hippocamp...
