Prenatal hypoxia is a state of reduced oxygen supply to fetal tissue that can lead to organ damage with long-term consequences. Brain damage can lead to mental retardation, cerebral palsy, epilepsy and behavioral disorders. For this reason, a large amount of research has been done on animal models, especially rats. In the neonatal rat, the stage of brain development matches the stage of brain development in the human fetus from the 23rd to the 34th week of pregnancy, when problems with hypoxia most often occur. Disadvantage of previously used invasive models of hypoxia is a difficulty to conclude whether the observed changes are the result of hypoxia or the operation itself. Therefore, the aim of this study was to develop a non-invasive model and to determine possible changes in locomotion, anxiety-like, exploratory and social behavior, and learning in young rats exposed to hypoxia in the normobaric chamber on the first postnatal day. In this study, young rats underwent the battery of behavioral tests: open field, hole board, T-maze and social choice, from the 33rd to the 34th postnatal day. The level of locomotion, anxiety-like and exploratory behavior did not differ between the groups. Compared to the control group, the hypoxia-exposed group had a significantly smaller number of correct choices in the T-maze. In addition males from the experimental group displayed prolonged research time of the conspecific in the social choice test. The findings suggest that the exposure of neonatal rats to hypoxia reduces the ability of spatial learning and increases the sociability in males.
