RESUMO
The aim of this research was to study the effect of 12-minute clinical death on innate and acquired behavior, biogenic amine concentration, and the composition and quantity of neural populations in specific brain regions of white rats. The study shows that in animals during the postresuscitation period with formal restoration of neurological status, there are changes in emotional reactivity, orientation-exploration reactions, impairment of learning and memory, decrease in exercise tolerance and pain sensitivity. These processes are accompanied by alterations in serotonin and norepinephrine levels in the frontal cerebral cortex, dopamine and serotonin levels in the striatum, certain biochemical indices in blood plasma and neural loss in the CA1 sector of the hippocampus and lateral portions of the cerebellum.

El propósito de este estudio fue examinar el efecto de una muerte clínica de 12 minutos de duración sobre el comportamiento innato y adquirido, la concentración amino biogénica, y la composición y cantidad de las poblaciones neuronales en regiones específicas en ratas blancas. El estudio muestra que durante el período con restauración formal del estatus neurológico, hay cambios en los animales en la reactividad emocional, las reacciones de orientación-exploración, trastornos de aprendizaje y memoria, reducción de la tolerancia al ejercicio y la sensibilidad al dolor. Estos procesos se acompañan de alteraciones en los niveles de serotonina y no repinefrina en la corteza cerebral frontal, en los niveles de dopamina y serotonina en el cuerpo estriado, ciertos índices bioquímicos en el plasma sanguíneo y pérdida neuronal en el sector CA1 del hipocampo y en porciones laterales del cerebelo (AU)
