Eye opening and increased motor activity after the second postnatal week in rats imply an extensive development of motor control and coordination. We show a parallel development change in spontaneous IPSC (sIPSC) kinetics in cerebellar granule neurons. sIPSCs were studied by whole-cell recordings in cerebellar slices, prepared from 7-30 postnatal day old(More)
The functional role of the large heterogeneity in GABAA receptor subunit genes and its role in setting the properties of inhibitory synapses in the CNS is poorly understood. A kinetic comparison between currents elicited by ultra-rapid application with a piezoelectric translator of 1 mM GABA to mammalian cells transfected with cDNAs encoding distinct GABAA(More)
Conflicting results, both decreased and increased, have been reported concerning the function of T-lymphocytes in heroin addicts. We investigated the alterations of T-lymphocyte proliferative responses and immunophenotypic markers on lymphoid cells in heroin addicts and during different periods of heroin withdrawal in addicted subjects. This study has(More)
Details of cerebellar afferent projections from the vestibular nuclei were investigated by the method of retrograde axonal transport of horseradish peroxidase (HRP) in the cat. The distribution of labeled cells in the vestibular nuclei following HRP injections in various parts of the cerebellum indicates that vestibular neurons in the medial and descending(More)
Horseradish peroxidase (HRP) was injected or iontophoretically ejected in various thalamic nuclei in 63 adult cats. In 11 other animals HRP was deposited outside the thalamic territory. The number and distribution of labelled cells within the vestibular nuclear complex (VC) were mapped in each case. To a varying degree all subgroups of VC appear to(More)
Little is known about how amyloid-beta (Abeta) is deposited in relation to the complex ultrastructure of the brain. Here we combined serial section immunoelectron microscopy with 3D reconstruction to elucidate the spatial relationship between Abeta deposits and ultrastructurally identified cellular compartments. The analysis was performed in a transgenic(More)
Details of cerebellar afferent projections from the perihypoglossal nuclei were studied in the cat by means of retrograde axonal transport of horseradish peroxidase (HRP). Labeled cells were observed bilaterally (with a preponderance ipsilaterally) in nuclei intercalatus and praepositus hypoglossi following injections in various folia of the entire vermis,(More)
Injections of horseradish peroxidase into the various parts of the cerebellar cortex and the cerebellar nuclei in the cat result in labelled cells within the reticular formation proper. All the reticular nuclei (with the exception of the reticular formation of the mesencephalon) send fibres to the cerebellum. The highest number of labelled neurons after(More)
