Funding Status: Planned-Funded - Task expected to be within budget
Procurement Mechanism(s):
Solicited
Aims:
This project “integrates” transdisciplinary approach with multiple research arms that use simulated galactic cosmic ray fields as the core feature with experimental design and conceptualization to assess interaction and time order-effects of radiation exposure (RE), isolation & confinement stress (ICS), and SM (sensorimotor responses to simulated microgravity). This project will use standardized handling and behavioral tests, assess brain physiology (including Blood-Brain-Barrier patency and function), molecular signaling, biomarker changes, and lead to computational modeling to characterize and predict changes in operationally-relevant “Brain Performance Pathways”. For purposes of this solicitation, NASA defines “Brain Performance Pathways” as the neural circuitry and associated molecular, cellular and physiological processes that underlie specific behaviors or sets of behaviors expressed in animal models that are translatable to humans.

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 - 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?

RiskRisk of Adverse Cognitive or Behavioral Conditions and Psychiatric Disorders
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.
