Task Description: Long-term exploratory class missions will increase the risk that astronauts will be exposed to significant doses of protons resulting from solar flares. Evaluating these risks requires knowledge of the potential effects of proton irradiation on a variety of endpoints, including central nervous system (CNS) functioning. However, the effects of exposure to protons on CNS function and on behavior have not been the subject of significant amounts of research. Limited research has produced equivocal results about the consequences of exposure to protons on neurochemical and behavioral endpoints, with some data suggesting an effect of exposure to protons on these endpoints and other data indicating no effect following exposure. The objectives of the experiments detailed in this proposal are to describe and evaluate the effects of exposure to protons on CNS function and behavior and to characterize the role of individual differences, such as gender and age, in modulating the effects of exposure on neurocognitive endpoints.

Task Progress & Bibliography Information FY2013 
Task Progress: The key findings are:

1. Exposure to 4He particles produces deficits in cognitive performance at doses of 0.1 to 0.5 cGy. These results are consistent with previous observations which indicate that as particle linear energy decreases, there is a concomitant decrease in the dose needed to disrupt cognitive performance.

2. Ovariectomized female rats given implants of estradiol in sesame oil or sesame oil alone (vehicle) prior to exposure to 12C particles. In contrast to the results obtained following exposure to 56Fe particles, there were no differences in cognitive performance as a function of hormonal status at the time of irradiation. The reasons for the differences in the effects of estradiol following exposure to different HZE particles remain to be established.

3. Preliminary data suggest that oxidative stress may play a role in mediating the changes in the disruption of autophagy and in the phosphorylation of tau protein following exposure to HZE particles. Because the hyperphosphorylation of tau protein gives rise to the development of neurofibrillary tangles, this data may link exposure to HZE particles to the development of neurodegenerative diseases, such as Alzheimer’s Disease. Rats that were maintained on antioxidant berry diets (strawberry or blueberry) did not show the changes in autophagy and the development of neurofibrillary tangles. These results indicate: (1) a causal relationship between radiation-induced oxidative stress and neurochemical changes in the central nervous system; and (2) that antioxidant diets may be able to function to reduce the possibility of nervous system dysfunction of exploratory class missions.

Task Progress & Bibliography Information FY2012 
Task Progress: The key findings are:

1. Protons (1000 MeV/n) produce deficits in cognitive performance. The dose of protons needed to produce a performance decrement is greater than that of 16O particles. These results are in general agreement with the results of a previous experiment in which rats were exposed to 1000 MeV/n protons at the NSRL.

2. Rats were given head-only, body-only, or whole-body exposures to 16O particles (1000 MeV/n). The effects of head-only exposures to 16O particles are similar to the results of previous studies showing that exposure to these particles produces a U-shaped function for the disruption of neurocognitive performance. The results also suggest that exposures involving the body may influence the responsiveness of the organism to the disruptive effects of exposure to HZE particles on neurocognitive performance.

3. Preliminary data suggest that oxidative stress may play a role in mediating the changes in the disruption of autophagy and in the phosphorylation of tau protein following exposure to HZE particles. Because the hyperphosphorylation of tau protein gives rise to the development of neurofibrillary tangles, this data may link exposure to HZE particles to the development of neurodegenerative diseases, such as Alzheimer’s Disease.

Task Progress & Bibliography Information FY2011 
Task Progress: The key findings are:

1. Age may be a risk factor for the behavioral effects of exposure to heavy particles and the effects are not necessarily linear. However it is possible that exposure to low LET particles such as 16O, in contrast to high LET 56Fe particles, may not produce an age-dependent performance decrement.

2. Exposure to gamma rays, 137Cs, does not produce significant changes in cognitive performance.

3. Exposure to 16O particles disrupts autophagy, the process by which the nervous system remove toxic proteins. It is possible that the disruption of this process contributes to the development of deficits in cognitive performance.

Task Description: Long-term exploratory class missions will increase the risk that astronauts will be exposed to significant doses of protons resulting from solar flares. Evaluating these risks requires knowledge of the potential effects of proton irradiation on a variety of endpoints, including central nervous system (CNS) functioning. However, the effects of exposure to protons on CNS function and on behavior have not been the subject of significant amounts of research. Limited research has produced equivocal results about the consequences of exposure to protons on neurochemical and behavioral endpoints, with some data suggesting an effect of exposure to protons on these endpoints and other data indicating no effect following exposure. The objectives of the experiments detailed in this proposal are to describe and evaluate the effects of exposure to protons on CNS function and behavior and to characterize the role of individual differences, such as gender and age, in modulating the effects of exposure on neurocognitive endpoints.

Task Progress & Bibliography Information FY2010 
Task Progress: The key findings are:

1. The neurobehavioral effects of exposure to different heavy particles from both acute and late degenerative effects of irradiation on CNS function may differ as a function of particle energy, fluence and the specific endpoint under consideration

2. Age may be a risk factor for the behavioral effects of exposure to heavy particles and the effects are not necessarily linear

3. Estrogen may not function as a neuroprotectant for exposure to HZE particles. The pattern of HZE effects on cognitive performance in ovariectomized female rats with/without estrogen replacement may vary as a function of the specific task.

4. Genes that directly or indirectly interact in the regulation of growth and differentiation of neurons were changed following irradiation; genes that regulate apoptosis were up-regulated whereas genes that modulate cellular proliferation were down-regulated, possibly to eliminate damaged cells and to stop cell proliferation to prevent DNA damage caused by radiation to new cells. These changes in gene expression may result from HZE particle-induced oxidative stress.

Present Experiments: Two sets of experiments are ongoing.

1. Rats were exposed to two energies of 48Ti (1100 and 500 MeV/n) particles to continue our studies of the role of differences in LET in determining the relative biological effectiveness of particles in disrupting neurocognitive performance.

2. Rats that had been previously exposed to 16O (1000MeV/n) particles were tested to continue the evaluation of the interaction between exposure to HZE particles and age on neurocognitive performance was evaluated by retesting rats at intervals up to 15 months following irradiation.
