Mutual interactions among cholinergic, noradrenergic and serotonergic neurons studied by iontophoresis of these transmitters in rat brainstem nuclei. During waking, presynaptic nicotinic facilitation of excitatory locus coeruleus noradrenergic inputs to the dorsal raphe enhances serotonergic firing. Since the alpha-2 receptor is inhibitory, this would be expected to result in an increase in locus coeruleus activity, with increased noradrenergic reactivity. The silence of noradrenergic neurons probably suppresses some relay nuclei facilitation. Therefore, reinforcement induced by probe trial experience might depend on noradrenergic activation. Hypotheses about the pathophysiology of depression have traditionally focused on the serotoninergic and noradrenergic systems. The noradrenergic innervation density of the monkey paraventricular nucleus is not altered by early social deprivation. Implications for theories of dorsal noradrenergic bundle function based on selective attention and arousal. Effects of lesions to ascending noradrenergic neurons on per formance of a 5-choice serial reaction task in rats. The experimental and theoretical results suggested that the serotoninergic system mediates positive reinforcement and the noradrenergic system mediates negative reinforcement. Prepubertal ovarian function is finely regulated by direct adrenergic influences: role of a noradrenergic innervation. Thirdly, whether aspects of personality or temperament would be associated with preference for either a noradrenergic or serotonergic selective agent. Galanin-mediated anxiolytic effect in rat central amygdala is not a result of corelease from noradrenergic terminals. Corticotropin-releasing factor activates noradrenergic neurons of the locus ceruleus. Corticotropin-releasing factor activates noradrenergic neurons of the locus coeruleus. More recently, many conflicting studies have appeared in the literature regarding noradrenergic function in depression. These have focused on the noradrenergic and serotonergic systems. |
