Функціональна асиметрія нервової системи безхребетних на прикладі просторової орієнтації твердокрилих триби tentyriini

Author(s): K. O. Moroz / Language(s): Ukrainian Issue: 2/2010

The functional asymmetry of the nervous system of insects was studied on an example of two taxonomically and ecologically closed darkling beetles: Anatolica eremita (Steven, 1829) and Tentiria nomas taurica (Pallas, 1781). Species-specificity of motor-spatial asymmetry is revealed for imago of these species. Spatial differentiation of specimens’ movement for “right-handers”, “left-handers” and “ambidexters” with different degree of the sign display was investigated. Fluctuations and distributing of values of the asymmetry ratio for both species of the darkling beetles were determined. Influence of the first priority of the locomotion direction on further orientational manifestations was analysed.

Author(s): N. A. Sitnik / Language(s): Russian Issue: 1/2010

Regularities of growth and dynamics of balance constituents of the energy budget of the flat oyster larvae in development are investigated. It is shown, that the linear growth in early ontogenesis is described by the exponential equation with high accuracy. Parameters of the functions connecting length, height and weight of larvae are defined. The quantitative characteristic of the energy balance elements of oysters larvae is given. It is shown, that during development from a veliger stage to a pediveliger the energy expenditures for growth, metabolism and nutriment assimilation increase more than 10 times. Net efficiency of larvae growth (coefficient К2) varies within 61.6–62.8 % during development, and the magnitude of a specific daily ration of oyster larvae equals 32–35 % of the energy equivalent of body weight.

Особенности расчета коэффициента синхронизации нейронных сетей

Author(s): S. О. Kochubey / Language(s): Russian Issue: 2/2009

The peculiarities of calculation of the synchronization coefficient in the brain neuronal network are discussed. The synchronization analysis is based on the cross-correlation of the action potential time for any pairs of neurons. The limitation of the method is a way of choosing the duration of time interval. It is used for transformation of the sequence of action potential chain to the binary numerical format with the following cross-correlation value calculation. Using optimization principle, which helps to define the network degree of synchronization exactly, we developed a method of the “optimal” time interval value determination.

Author(s): G. A. Zadorozhnaya,V. Lyashenko,A. I. Rudenko,O. Z. Melnikova,T. G. Chaus / Language(s): Ukrainian Issue: 1/2009

The dynamics of spectral composition of electric activity in the trophotropic and ergotropic areas of the rat hypothalamus during long time stress (21 week) and action of the left directed vortical impulsive magnetic field (MF) were investigated. It was discovered that effects of vortical MF influence depend both on the initial state of studied cerebral structure and the period of influence. Under physiological condition the MP influence leads to synchronization in spectral composition of electrohypotalamogramme (EGtG) that was expressed by theta-rhythm increasing. The formation of diphasic EGtG as a successive replacement of the desynchronization by synchronization of electric activity due to high-frequency components was observed under the combined influence of stress and MF.
