Ontogenesis of learning: I. Variation in the rat's reflexive and learned responses to gustatory stimulation.

abstract：:Brain monoaminergic neurotransmitters, such as dopamine (DA), serotonin (5-HT), and noradrenaline (NA), play crucial roles in neuronal and physiological functions, including social behaviors. Isolation housing may induce behavioral and neurochemical abnormalities in rats, although its influence on neurotransmitter lev...
