The role of hypoxia in the integrity of the genetic apparatus and the formation of memory in drosophila in the paradigm of conditioned reflex suppression of courtship

Abstract

M.E. Lobashev and V.В. Savvateev in 1959 obtained unique data on the expansion of the adaptive capabilities of the organism when training the properties of higher nervous activity by the formation of conditioned food reflexes to stimuli that exhaust the nervous system. Apparently, the formation of a conditioned connection help to overcoming stressful effects, adaptation to restrictive conditions, and changes in the functioning of the nervous system. To test this assumption, the influence of stressful influences hypoxia on learning and memory of Drosophila in the paradigm of conditioned reflex suppression of courtship was studied. The results were obtained on the enhancement of the ability to learn under hypoxic exposure. These experimental conditions did not affect memory formation. The effect of hypoxia on chromosomes through the formation of double-stranded breaks was revealed. The data are discussed in light of the relationship between neuroplasticity processes and mechanisms of adaptation to stressors.
