Short Title: HZE Behavior and Neural Circuitry
Responsible HRP Element: Space Radiation

Funding Status: Active - Currently funded and in progress
Procurement Mechanism(s):
Solicited
Aims:

Aim 1: The impact of HZE particles on other tests in the cognitive domain. Using the “flexible battery” of tests offered by the touchscreen operant platform, we will identify a behavioral framework for the HZE particle-induced improvement in pattern separation.


Aim 2: The impact of HZE particles on behaviors in the affective/social domain.


Aim 3: Indices of neural network perturbation underlying HZE particle exposure induced improved pattern separation

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?
GapCNS - 6: How can new knowledge and data from molecular, cellular, tissue and animal models of late CNS risks or clinical human data be used to estimate late CNS risks to astronauts from GCR and SPE?

RiskRisk of Adverse Cognitive or Behavioral Conditions and Psychiatric Disorders
GapCBS-BMed3: We need to identify and quantify the key threats to and promoters of mission relevant behavioral health and performance during autonomous, long duration and/or long distance exploration missions.
