Changes in the behavioral response to a novel environment following lesioning of the central dopaminergic system in rat pups.

abstract：OBJECTIVE:The aim of our study was to test whether ketamine produces an antidepressant effect in animal model of olfactory bulbectomy and assess the role of mammalian target of rapamycin (mTOR) pathway in ketamine's antidepressant effect. METHODS:Bulbectomized (OBX) rats and sham controls were assigned to four subgrou...
