Article Synopsis
- Astronauts on missions like Mars will face exposure to high-energy HZE particles, which can affect brain function and cognitive abilities.
- Research using rats showed that different types of radiation exposure (head-only, body-only, or whole-body) did not consistently impact behavior or neurochemistry.
- The findings imply that body radiation can influence the brain, indicating a need to reassess the risks associated with HZE particles on cognitive performance.

Exposure to the types of radiation encountered outside the magnetic field of the earth can disrupt cognitive performance. Exploratory class missions to other planets will include both male and female astronauts. Because estrogen can function as a neuroprotectant, it is possible that female astronauts may be less affected by exposure to space radiation than male astronauts.

Article Synopsis
- Astronauts on exploratory missions are exposed to heavy particles that can affect cognitive performance, particularly noting that lower linear energy transfer (LET) particles require a smaller dose to impact cognition.
- Research has identified that exposure to low LET helium (He) particles could contribute significantly to the total radiation dose astronauts face.
- Findings indicate that even low doses of He particles (as low as 0.01-0.025 cGy) can cause changes in neuronal function and cognitive performance, suggesting a higher risk of cognitive deficits for astronauts than previously understood.
