Abstract
Intermittent hypoxia (IH), a characteristic of sleep apnea, was modeled in Fischer Brown Norway rats (10Â h/day for 7Â days) followed by cognitive testing in an attentional set-shifting task. The ability to shift attention from one sensory modality (e.g., odor) to another (e.g., digging medium) was impaired, a finding that could not be attributed to deficits in attention, discrimination, learning, or motor performance. Instead, the deficit is likely to reflect impaired allocation of attentional resources of the working memory system.
