Comparative analysis of the probability, direction and magnitude of changes of the mean firing rates for the background and L-glutamate--(Glu) and acetylcholine--(ACh) induced activity of single sensorimotor cortical neurons of unanesthetized rats showed that more significant changes occurred in reaction to the applications of Glu. Increases of Glu-induced(More)
A morphometric investigation of various components of the synapses of neurons of the sensorimotor region of the cerebral cortex of rats with different variants of combined and uncombined repeated microiontophoretic application of glutamate and acetylcholine has been carried out, A substantial dependence of the character and expressivity of the(More)
As a result of acetylcholine iontophoresis with different currents 3-fold increase of transmitter compared with the threshold one for reaction has been shown not to result in change of a type of reaction pattern more than in 80.3% of neurones. Such increase of action force is quite enough for the significant lengthening of the reaction excitatory components(More)
BACKGROUND Multivitamin/mineral products (MVMs) are the dietary supplements most commonly used by US adults. During manufacturing, some ingredients are added in amounts exceeding the label claims to compensate for expected losses during the shelf life. Establishing the health benefits and harms of MVMs requires accurate estimates of nutrient intake from(More)
Numerous studies have demonstrated an important role for cholinergic and glutamatergic signal transduction in the cerebral cortex in the processes of learning and memory. The results of our own studies have shown [1] that repeated combined microapplication of glutamate and acetylcholine induce ultrastructural changes in axodendritic synapses, with increases(More)
A comparative study of the probability, directionality, and intensity of the changes in the baseline and L-glutamate (Gl)- and acetylcholine(ACh)- induced average frequency of the impulse activity (BIA, GIIA, and AChIA, respectively) of individual neurons of the sensorimotor cortex of unanesthetized rats in the course of repeated isolated and combined(More)
Comparative analysis of the probability, direction and magnitude of changes of the mean firing rates for the background and L-glutamate--(Glu) and acetylcholine--(ACh) induced activity of single sensorimotor cortical neurons in the course of repeated separate and paired presentations of Glu and ACh was carried out in unanesthetized rats. A decline of(More)
