The turnover rate of acetylcholine receptors at neuromuscular junctions in mice increases progressively after denervation and, after 15 days, reaches a half-time of 30 z 5 hours. Denervation thus causes the clustered junctional acetylcholine receptors to assume the rapid turnover characteristic of extrajunctional receptors before innervation.
This study compared the relative importance (i.e., proportion of shared variance) of attentional capacity and processing speed accounts of cognitive aging to predict age differences in episodic and working memory performance. Right-handed adults (n = 100), 18 to 88 years of age, completed measures of attentional capacity (divided attention), processing(More)
The performance of 54 patients with complicated mild-severe traumatic brain injury (TBI) was evaluated on the Attention, Executive Functions, and Memory modules of the Neuropsychological Assessment Battery (NAB) and compared with that of 54 demographically matched healthy controls. All three NAB indices demonstrated statistically significant group(More)
