Aims:
1. To assess the effects of space radiation across a range of cognitive/behavioral functions in rodents. Performance measures include assessments of general motor function and speed, fine motor control, inhibitory control (impulsivity), timing, short-term memory, spatial working memory, learning and selective attention, motivation, and basic sensory function.
2. To assess the long-term effects of radiation across a range of cognitive/behavioral functions via extended post-exposure testing for potential performance deficits.
3. To assess both the acute and long-term effects of radiation on the neurochemical mechanisms underlying changes in cognitive/behavioral functions by examining the integrity of the neurotransmitter systems known to mediate those neurobehavioral functions found impaired.
