Stress induces supersensitivity of a cholinergic system in rats.
Cholinergic system supersensitivity may be involved in the pathophysiology of depressive disorders (Janowsky et al. 1972; Dilsaver and Greden 1984; Dilsaver 1986). Associations between stressful events and onset of depressive (Lloyd 1980) and manic (Kennedy et al. 1983) episodes are documented. Janowsky et al. (1983) proposed that stress increases the sensitivity of central cholinergic mechanis...
متن کاملCold stress and cholinergic supersensitivity.
To the Editor: In the rat (adult male Sprague-Dawley) chronic forced swim stress (Dilsaver et al. 1986) and chronic inescapable footshock (Dilsaver and Alessi 1987) induce marked supersensitivity to the hypothermic effects of the muscarinic cholinergic agonist oxotremorine. These observations are consistent with a report that immobilization of 10 min duration activates the septohippocampal musc...

متن کاملDissociation of cholinergic supersensitivity from receptor number in ciliary muscle.
Ciliary ganglionectomy in the cynomolgus monkey produced loss of the accommodative response to electrical stimulation of the Edinger-Westphal nucleus and to topical eserine, concurrent with enhanced responsiveness to topical and systemic pilocarpine. This supersensitivity produced by parasympathetic denervation was not associated with an increase in muscarinic receptor number or affinity measur...
متن کاملKisspeptin-13 ameliorates memory impairment induced by streptozotocin in male rats via cholinergic system
Introduction: Kisspeptin-13 (KP-13) is a novel endogenous factor, increases synaptic transmission and is involved in several behavioral functions such as anxiety, locomotion, epilepsy and avoidance learning. However, the role of this peptide on cognition has not been well clarified yet. Here we studied the effect of kisspeptin-13 pretreatment on spatial learning and also interaction with cholin...
