Nucleus basalis magnocellularis and medial septal area lesions differentially impair temporal memory.
Functional dissociations between the medial septal area (MSA) and the nucleus basalis magnocellularis (NBM) were examined using the concepts and experimental procedures developed by scalar timing theory. Rats were tested in variations of a signalled discrete-trial peak-interval schedule of reinforcement in which the response rate functions identified the time when the rats expected reinforcemen...
متن کاملLesions in nucleus basalis magnocellularis and medial septal area of rats produce qualitatively similar memory impairments.
The functional contribution of nucleus basalis magnocellularis (NBM) and the medial septal area (MSA) to memory was evaluated in two different spatial discriminations. Preoperatively, rats were trained to a criterion level of performance in a simultaneous left/right discrimination on the stem of a T-maze (a trial-independent memory) and a discrete-trial, rewarded alternation discrimination on t...
متن کاملDifferential effects on spatial navigation of immunotoxin-induced cholinergic lesions of the medial septal area and nucleus basalis magnocellularis.
The effects on anatomy and behavior of a ribosomal inactivating protein (saporin) coupled to a monoclonal antibody against the low-affinity NGF receptor (NGFr) were examined. In adult rats, NGFr is expressed predominantly in cholinergic neurons of the medial septal area (MSA), diagonal band nuclei, and nucleus basalis magnocellularis (nBM), but also in noncholinergic cerebellar Purkinje cells. ...
متن کاملEffects 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) ...
