The ratio of the period of cardiac cycle to the period of vessel autofluctuations is constant in healthy resting humans. This ratio constitutes 1.309 +/- 0.068. The same correlation is observed between the duration of the pneumo-cycle and the period of respiratory arrhythmia. At working and post-constriction hyperemia, there is a resonance in cardiac-respiratory-hemodynamic system that synchronizes the fluctuation processes of its constituent elements and increases the RVG amplitude. The data obtained have been discussed. 相似文献

Experimental data are presented on evaluating the efficiency of auditory perception of the dolphin Tursiops truncatus of tonal signals of different duration and of the fixed energy on the background of Gauss obstacle. The dependence of percepting properties on time characteristics of the signal are stated. A comparative analysis of the efficiency of dolphin auditory system with that of the coordinated filter is carried out. Biological receiving systems are shown to be adaptive. The self-tuning linits of the dolphin auditory system at a given level of the possibility of correct detection are determined. 相似文献

Morphological studies have been made of the neocortical and archicortical structures in the spiny mouse Acomys cahirinus, the only maturely born species from the family Muridae. The data obtained reveal highly developed hippocampus as compared to the neocortex in this mouse, in contrast to relationships found in other mice and rats. 相似文献

Rhynchospio glutaea (Ehlers, 1897), Rhynchospio arenincola Hartman, 1936 and Rhynchospio arenincola asiatica Chlebovitsch, 1959, originally described from Strait of Magellan, California, and South Kurile Islands respectively, appear similar to each other in adult morphology. These species and subspecies have been considered by some authors as subjective synonyms and are here referred to as members of the R. glutaea complex. Sequence data of four gene fragments (2465 bp in total) of the mitochondrial 16S rDNA, nuclear 18S and 28S rDNA, and Histone 3 have shown that R. glutaea complex individuals from the South West Atlantic (Argentina), North East Pacific (British Columbia and Oregon) and North West Pacific (South Korea) were genetically distant and not conspecific. These data also indicate that R. arenincola from North America and R. aff. asiatica from South Korea are more closely related to each other, and both are closer to R. glutaea from South America than to R. nhatrangi from Vietnam: nhatrangi (glutaea (arenincola-aff. asiatica)). Adults of the R. glutaea complex are hermaphrodites and the arrangement of gametes is suggested to be a crucial reproductive character for distinguishing these species. Based on this character, two species of the complex are apparent in the North West Pacific: R. asiatica Chlebovitsch, 1959 stat. nov. from the Kurile Islands (not analysed here) and an unnamed species from the mainland coast of Asia (here referred to as R. aff. asiatica). Adult morphology of R. asiatica stat. nov. is briefly described and illustrated. The lectotype and the type locality of the species on Iturup Is. are established for the first time. An identification key is provided to the 10 currently recognized Rhynchospio species. 相似文献
