By means of a condenser discharge electric shock paradigm, "dark" (compacted) granule neurons were momentarily produced in the hippocampal dentate gyri of rats, which were sacrificed either immediately or following survival periods ranging from 1h to 30 days. Except for the morphological changes related to the formation, recovery or death of the "dark"(More)
Calretinin-containing neurons in the hippocampal formation, including the subiculum, presubiculum, parasubiculum, and entorhinal cortex, were visualized with immunocytochemistry. Calretinin immunoreactivity was present exclusively in non-principal cells. The largest immunoreactive cell population was found in the outer half of the molecular layer of the(More)
In this paper we introduce a new technique for data-dependent triangulation which is suitable for implementation on a GPU. Our solution is based on a new parallel version of the well known Lawson's optimization process and is fully compatible with restrictions of the GPU hardware. We test and compare the quality of our solution in an image reconstruction(More)
A new weight-drop head-injury apparatus is described that can produce a momentary depression of predetermined depth at a predetermined site of the elastic calvaria of scalped young adult rats. In Wistar rats weighing about 200 g, a 0.75-mm deep calvaria depression immediately caused ultrastructural (neurofilament) compaction in many long axon segments,(More)
—Agglutinative languages, such as Hungarian, use inflection to modify the meaning of words. Inflection is a string transformation which describe how can a word converted into its inflected form. The transformation can be described by a transformational string. The words can be classified by their transformational string, so inflection is considered as a(More)
