Journal ArticleDOI
Hippocampal synaptic plasticity and spatial learning are impaired in a rat model of sleep fragmentation
Jaime L. Tartar,Christopher P. Ward,Christopher P. Ward,James T. McKenna,Mahesh M. Thakkar,Elda Arrigoni,Robert W. McCarley,Ritchie E. Brown,Robert E. Strecker +8 more
TL;DR: The results suggest that sleep fragmentation negatively impacts spatial learning, and loss of N‐methyl‐d‐aspartate receptor‐dependent LTP in the hippocampal CA1 region may be one mechanism involved in this deficit.
Journal ArticleDOI
Environmental enrichment: effects on spatial memory and hippocampal CREB immunoreactivity.
Beverly M. Williams,Yuan Luo,Christopher P. Ward,Kacy J. Redd,Russell Gibson,Stan A. Kuczaj,John G. McCoy +6 more
TL;DR: Results indicate that environmental enrichment (particularly during the earlier period) improved performance on the Morris water maze and tended to increase immunoreactivity to CREB in the hippocampus and the importance of the developmental period for enrichment.
Journal ArticleDOI
Sleep fragmentation elevates behavioral, electrographic and neurochemical measures of sleepiness.
James T. McKenna,Jaime L. Tartar,Christopher P. Ward,Mahesh M. Thakkar,Joshua Cordeira,Robert W. McCarley,Robert E. Strecker +6 more
TL;DR: Findings imply an elevation of the homeostatic sleep drive following either 6 or 24 h of SI, and BF AD levels appear to correlate more with sleepiness than with the cumulative amount of prior wakefulness, since total NREM sleep time declined only slightly.
Journal ArticleDOI
Experimental sleep fragmentation and sleep deprivation in rats increases exploration in an open field test of anxiety while increasing plasma corticosterone levels
Jaime L. Tartar,Christopher P. Ward,Christopher P. Ward,Joshua Cordeira,Steven L. Legare,Amy J. Blanchette,Robert W. McCarley,Robert E. Strecker +7 more
TL;DR: Plasma corticosterone levels of sleep disturbed and exercise control rats were elevated compared to cage controls, suggesting that the increased exploration observed in the sleep disturbed rats was not due to a hypothalamic-pituitary-adrenal (HPA) stress response.
Journal ArticleDOI
Academic stress differentially influences perceived stress, salivary cortisol, and immunoglobulin-A in undergraduate students
TL;DR: Investigating biochemical and self-report measures of stress, immune functioning, and academic pressures before and during a midterm examination period provides new insight into the complex relationship between examination stress, cortisol, and immune functioning.
