Procurement Mechanism(s):

The present proposal addresses this need via the application of an animal model to determine:

  1. The long-term effects of radiation exposure on cognitive neurobehavioral function and the dopamine neurotransmitter system; and
  2. The effectiveness of flaxseed dietary supplementation to mitigate the neurobehavioral and neurochemical effects of radiation exposure.
  3. To determine DAergic and inflammatory protein levels in radiation-induced, neurobehaviorally impaired Fischer and Lewis rats and in radio-protectant-treated flaxseed rats.
  4. To assess functional changes in dopaminergic neurotransmission following head-only proton radiation using well-characterized dopamine receptor-mediated behaviors (i.e., DA agonist-induced yawning and hypothermia)
