A method to create dynamic models of microwave transistor systems is described. In systems with inertia, exhibiting regular and complicated dynamics, evolution of the auto-oscillation process depends both on the connection of inertial chain and on the type of dynamic characteristics of the nonlinear amplification element. These systems may be used in(More)
By means of in vivo microdialysis combined with HPLC analysis, we have shown that local infusions of 1 mM N-nitro-L-arginine (NO-synthase inhibitors) in the rat striatum reduced, and infusions of 100 microM apomorphine (agonists of the dopamine receptors) increased the level of citrulline (a NO co-product) in extracellular space of this structure. The(More)
The creation of an accounting set of binary orthogonal chaotic sequences is numerically investigated on the basis of a base sequence with use of a time delay about the characteristic period of the chaotic function. A method of formation of a base chaotic binary sequence is offered using a temporary realization of chaotic function.
In vivo intracerebral microdialysis/HPLC studies on Sprague-Dawley rats showed that simultaneous presentation of food and a tone previously combined with a pain stimulus was accompanied by transient elevation of the glutamate level in the extracellular space of the nucleus accumbens, the extent of this increase being proportional to the latent period of(More)
By means of in vivo microdialysis combined with HPLC analysis, we have shown that extracellular levels of citrulline (NO co-product) and arginine (NO precursor) increase in the rat n. accumbens during acquisition and expression of a classical fear response. The conditioned rise of citrulline and arginine levels gradually decreased in the course of(More)
