Cone photoreceptors in teleost fish are organized in precise, crystalline arrays in the epithelial plane of the retina. In zebrafish, four distinct morphological/spectral cone types occupy specific, invariant positions within a regular lattice. The cone lattice is aligned orthogonal and parallel to circumference of the retinal hemisphere: it emerges as(More)
The contents of noradrenaline, dopamine, and serotonin in the frontal cortex and hippocampus of rats demonstrating dominant, balanced, and submissive types of behavior were examined. The serotonin content in submissive males was considerably lower than that in balanced and dominant animals. The content of noradrenaline was lower in dominant individuals and(More)
Correlation between the level of testosterone in blood plasma and serotonin content in hippocampus and frontal cortex was investigated in aggressive and submissive rats of different age groups. Dependence of the testosterone level on behavior type was found. The highest testosterone level was observed in aggressive animals. In submissive males we found(More)
The influence of per os administered kynurenic acid on the glutamate, aspartate, glycine and GABA levels in the rat brain areas depended on the initial level of seizure susceptibility. The highest resistance of investigated parameters to the influence of kynurenic acid was found in the cerebellum of rats with low seizure susceptibility. The considerable(More)
The effects of per orally administered tryptophan on serotonin and GABA levels in different brain areas were found to depend on initial levels of seizure susceptibility. Elimination of difference in the content of investigated mediator between animals with high and low seizure susceptibility was observed. Serotonin level was approximated to the initial one(More)
The influence of kynurenic acid on the catecholamine contents in brain of rats with different seizure susceptibility was studied. In animals with high seizure susceptibility the decrease in norepinephrine content and the increase in the coefficient ratio between dopamine and norepinephrine have been found in the most of the regions investigated. Kynurenic(More)
