Central noradrenaline depletion antagonizes aspects of d-amphetamine-induced hyperactivity in the rat

TL;DR: Central NA depletion via either systemic DSP4 or neonatal 6-OHDA antagonised the amphetamine-induced increase in rearing behaviour, whereas lesions of the dorsal noradrenergic bundle using 6-hydroxydopamine antagonized the increase in locomotor activity.

Selective attention and place navigation in rats treated prenatally with methylazoxymethanol
TL;DR: Female MAM-treated rats failed to demonstrate contextual control of latent inhibition, which confirms earlier findings with male rats, and biochemical analyses indicated considerable increases in catecholamine levels in the cerebral cortex, hippocampus and striatum.

T-maze learning, spontaneous activity and food intake recovery following systemic administration of the noradrenaline neurotoxin, DSP4.
TL;DR: Both the NA-accumulation data and endogenous NA concentrations indicated profound NA, but not 5-hydroxytryptamine (5-HT) and dopamine (DA), depletions in the cortex, hippocampus and cerebellum, seem to confirm the role of the locus coeruleus-noradrenaline (LC-NA) system in an instrumental learning situation.

Role of olfactory bulbectomy and DSP4 treatment in avoidance learning in the rat.
TL;DR: The double dissociation between bulbectomized and D SP4-treated rats is discussed in terms of opponent behavioral processes, influenced by olfactory bulbectomy and DSP4, which may permit insights into experimental investigations of stress, anxiety, and depression.

Impaired selective attention in methylazoxymethanol-induced microencephalic rats.
TL;DR: It is indicated that MAM treatment disrupts attentional processes and that this may account for the learning impairment in microencephalic rats.
