L-glutamate appears to be a major excitatory neurotransmitter in the hypothalamus. Its action is mediated via ionotropic and metabotropic glutamate receptors (mGluR). Eight mGluRs have already been cloned. In the present study the hypothalamic distribution of mGluR1a has been investigated by immunocytochemistry using monoclonal antibodies recently produced(More)
In the septal complex, both parvalbumin and calbindin neurons cocontain GABA. In the same area, a large number of GABA-GABA synaptic connections can be observed. In order to further characterize their neurochemical nature, as well as the extrinsic and/or intrinsic origin of these GABA terminals, the following experiments were performed: (1) correlated(More)
Using a combination of electron microscopic autoradiography and immunocytochemistry, the connections between serotoninergic axons and somatostatin neurons of the anterior periventricular nucleus of the rat hypothalamus were examined. The serotoninergic elements were identified after selective uptake of tritiated serotonin and the somatostatin neurons with(More)
The authors have examined the importance of the autopsy from several aspects of view as the primary cause of death, comparison between clinical and pathological diagnosis, recognition of clinically unknown diseases, as well as new anatomical constellations, epidemiological data, assessment of effectiveness of modern imaging technics, authenticity of(More)
