Using NADPH-diaphorase histochemistry, distribution of reactive neurons in the forebrain structures and motor cortex of rats was studied. Some reactive (NO-generating) neurons are associated with microvessels and, thus, can be involved in the regulation of regional blood flow.
We studied manifestations of increased neuronal activity in the limbic structures of the rat brain related to realizations of operant reflexes by the animals. After rats had performed repeated operant foodprocuring movements, the mean numbers of Fos-immunoreactive neurons within sections of the central and basolateral amygdalar nuclei, insular cortex,(More)
We estimated in rats the expression of early gene c-fos (marker of neuronal activation) and NADPH-diaphorase activity (NO-synthase marker) in the limbic structures of the basal forebrain and in the hypothalamus. Estimations were performed in the norm, in the state of starvation, and after realization of long-lasting (repeated 4 to 12 times per minute for 30(More)
The expression of early c-fos gene (marker of neuronal activation) and NADPH-diaphorase reactivity (NADPH-dr) was studied in various hypothalamic structures of rats in the norm, in the state of starvation, and after realization of long-lasting (repeated 4 to 12 times per minute for 30 min) motivated stereotyped food-procuring forelimb movements. In rats in(More)
After stimulation of GABA-ergic synaptic connections in a culture of hippocampal neurons by a series of depolarizing current pulses (5-45 sec-1, 5-20 stimuli), an inhibitory postsynaptic current (IPSC) consisting of a phasic component and an asynchronous component develops in the postsynaptic neuron. In experiments with simultaneous recording from two(More)
