The markers of impairments of the nervous system were evaluated in rats at various time points after a sodium thiopental injection at the LD50 using biochemical and immunohistochemical methods. The thiopental coma state was associated with a decrease in the levels of superoxide dismutase 6 h after the injection, glucose-6-phosphate dehydrogenase 24 and 72 h… (More)
We performed immunohistochemical analysis of the expression of caspases 3, 9 and bcl-2 protein in rat brain at various terms after administration of LD50 of sodium thiopental. Expression of the specified apoptosis markers was found in the sensorimotor cortex and hippocampus (dentate gyrus and CA2 region).
This review summarizes studies directed to seeking the neuroanatomical basis of associative learning (conditioned olfactory proboscis-extension feeding reflex) in honeybees. Data on the structure of the bee brain are presented. Parallel pathways involved in responses to conditioned and unconditioned stimuli are demonstrated. The contributions of various… (More)
The review summarizes current concepts on the role of several covalent post-translational chromatin modifications during memory formation in vertebrates and invertebrates. It describes a sequence of intracellular events from activation of receptors and signal pathways up to changes in the functional state of genome.
A review. Works related to research into the neuroanatomical basis of associative learning in the honeybee (proboscis extension reflex) are summarized. Data on the brain organization of the honeybee are presented. The parallel neural pathways of conditioned and unconditioned stimuli are shown. Contribution of different brain structures and identified… (More)
