| Popis: | Morphometric studies of human forebrain formations composed of densely branched cells — the entorhinal cortex, the basolateral amygdala, the nucleus accumbens, the striatum, and the dorsal thalamus — were performed using nine parameters, with statistical analysis of the resulting data; measurements addressed the major projection-type densely branched and sparsely branched reticular neurons (scattered reticular and marginal reticular cells of the dorsal thalamus) stained by the Golgi method and with NADPH-diaphorase. Scattered reticular cells in the various formations showed no differences in any of the nine measures, while there were significant differences (in 5–7 measures, apart from one comparison, where there were differences in two measures) in their major projection-type densely branched cells. Scattered reticular and main projection-type densely branched neurons in each formation differed in terms of 7–9 measures. In endbrain formations, scattered reticular neurons contained NADPH-diaphorase; in the dorsal thalamus, only intermediate marginal reticular neurons were NADPH-diaphorase-positive. Thus, these human formations contained a common system of ancient integrative NADPH-diaphorase-containing reticular cells. Our results, along with published data, show these to be projection-type cells with projections to layers V and VI of the neocortex, which suggests that they have modulatory influences on its descending systems. |
