Effects of exercise on spatial memory deficits induced by nucleus basalis magnocellularis lesions
Introduction: Previous studies have shown that exercise enhances cognitive and functional capacities in patients with Alzheimer's disease (AD). In this study, we investigated the effect of long-term (60 days) and short- term (10 days) exercise on the spatial memory deficits in an animal model of AD. Methods: Fifty male rats were divided into 5 groups 1) intact, 2) sham, 3) sham-Alzheimer 4) ...
متن کاملFunctional and neurochemical cortical cholinergic impairment following neurotoxic lesions of the nucleus basalis magnocellularis in the rat.
The effect of kainic and quinolinic acid on cortical cholinergic function was examined following injections of these agents into the nucleus basalis magnocellularis (nbm) or into the frontoparietal cortex. The release of cortical 3H-acetylcholine (3H-ACh), high affinity choline uptake (HACU) and acetylcholinesterase was measured 7 days following injections of saline (control), kainic acid (4.7 ...

15 صفحه اولCortical muscarinic receptor function following quinolinic acid-induced lesion of the nucleus basalis magnocellularis.
Phosphatidylinositol metabolism, linked to muscarinic receptor activation, was studied in rat cortical slices after a unilateral quinolinic acid lesion to the nucleus basalis magnocellularis (nbM) or the cortex itself. The incorporation of [3H]inositol into inositol phosphate was measured in the presence of LiCl, followed by anion exchange chromatography to separate inositol phosphates. Carbach...
