TL;DR: The data suggest that declarative memory, and the ability to transitively infer established rules, also remained intact in the irradiated rats, and cognitive performance studies that use naïve rodents, thus requiring task rule acquisition as well as task performance, are likely to overestimate the risk of 56Fe-induced cognitive deficits.

TL;DR: While radiation-induced changes in synaptic plasticity in the PrL cortex may be associated with cognitive impairment, they are most likely not the sole determinant of the incidence and severity of such impairments.

TL;DR: The notion that “mission-relevant” doses of HZE particles can impair certain aspects of attentional set-shifting performance in retired breeder rats is supported, but there may be some ion-specific changes in the specific cognitive domains impaired.

TL;DR: Protracted low dose and low dose rate neutron exposures impairs executive functions in a high percentage of rats that were normally rested, however further detriments in performance become evident when the rats are subjected to sleep fragmentation.

TL;DR: Assessment of the effect that exposure to 5–20 cGy 1 GeV/n 48Ti had on the spatial memory performance of socially mature male Wistar rats further support the notion that the LET dependency of neurocognitive impairment may differ from that of cell killing.
