Aims:
1) identify the high-LET radiations that have the greatest impact on the ability of animals to recall imprinted memories and to learn new memory skills;
2) use PET imaging to identify the regions of the brain that are functionally inactivated when brain function is inhibited by Hze radiation
3) establish the relative importance of radiation-induced cell death and signal malfunction in the inhibition of brain function after exposure to radiations with low, medium and high-LETs;
4) develop a blood-based assay that can be used to monitor the astronauts for early signs of radiation-induced memory function deficit.
