Abstract
Our recent researches demonstrate shifts in brain activity of rats, both at behavioral and biochemical levels, induced by one of modeled impacts of interplanetary spaceflight, i.e. space radiation. Thus emerges a question, whether such shifts occur in molecular underlying processes of brain function. We have investigated the gene expression for proteins of SNARE (soluble NSF attachment receptor), responsible for fusion of transport vesicles with terminal membranes. Our result is an evidence of changes in some SNARE elements after irradiation and an indirect evidence of a link between nature of such changes and animal nervous system typology. Thus, in order, impairments of brain activity after model irradiation compared to such of an interplanetary flight are observed at every level of nervous system structure.
