Aims:
Research project focused on developing scientifically plausable, heuristic, computational models using Non-Human Primates (NHP) and radiation exposures (both clinical and space relevant,  in combination with other CBS realted spaceflight stressors) in order to assess, characterize and derive and valdiate operationally-relevant  models of performance outcome levels relative to radiation exposures (in combination with other CBS realted spaceflight stressors), dose effects and countermeasures for CBS integrated risk exposures in humans. An important aspect of this effect involves the conceptualization of research that is "reverse translation" in which consideration is given to the specific biological markers with significant operationally-relevant performance consequences are first determined in human models and then applied to an animal model to see if they exist and that they reflect the same performance decrements as evidenced in humans. This approach will facilitate the identification of novel biomarkers linked to different levels of performance (impact by CBS synergistic risks) with the introduction of CBS integrated risk at different stages of mission-relevant performance demands in the animal models. This also offers the potential to identify biomarkers related to the brain performance pathways.

RiskRisk of Acute (In-flight) and Late Central Nervous System Effects from Radiation Exposure
GapCBS-CNS - 1: Are there significant adverse changes in CNS performance in the context and time scale of spaceflight operations? If so, how is significance defined, and which neuropsychological domains are affected? Is there a significant probability that space radiation exposure would result in adverse changes? What are the pathways and mechanisms of change?
GapCBS-CNS - 2: Does space radiation exposure elicit key events in adverse outcome pathways associated with neurological diseases? What are the key events or hallmarks, their time sequence and their associated biomarkers (in-flight or post-flight)?
GapCBS-CNS - 3: How does individual susceptibility including hereditary pre-disposition (e.g. Alzheimer’s, Parkinson’s, apoE allele) and prior CNS injury (e.g. concussion, chronic inflammation or other) alter significant CNS risks? Does individual susceptibility modify possible threshold doses for these risks in a significant way?
GapCBS-CNS - 4: What are the most effective medical or dietary countermeasures to mitigate CNS risks? By what mechanisms are the countermeasures likely to work?
GapCBS-CNS - 5: How can new knowledge and data from molecular, cellular, tissue and animal models of acute CNS adverse changes or clinical human data, including altered motor and cognitive function and behavioral changes be used to estimate acute CNS risks to astronauts from GCR and SPE?
GapCBS-CNS - 8: Are there significant CNS risks from combined space radiation and other physiological or space flight factors, e.g., psychological (isolation and confinement), altered gravity (micro-gravity), stress, sleep deficiency, altered circadian rhythms, hypercapnea, altered immune, endocrine and metabolic function, or other?

GapCBS-BMed2: We need to identify and validate measures to monitor behavioral health and performance during exploration class missions to determine acceptable thresholds for these measures.

GapCBS-SM24: Determine if the individual capacity to produce adaptive change (rate and extent) in sensorimotor function to transitions in gravitational environments can be predicted with preflight tests of sensorimotor adaptability.
GapCBS-SM26: Determine if exposure to long-duration spaceflight leads to neural structural alterations and if this remodeling impacts cognitive and functional performance.
