Distribution and characterization of doublecortin-expressing cells and fibers in the brain of the adult pigeon (Columba livia)
The VZ in the brain of adult pigeons seems to have rapidly dividing cells as putative progenitors of newborn neurons populating the forebrain, suggesting that the morphological turnover of forebrain circuits is an important mechanism for brain plasticity in avian species during adulthood.
Influence of enrichment on behavioral and neurogenic effects of antidepressants in Wistar rats submitted to repeated forced swim test
Antidepressants or enrichment counteracted the high immobility in rFST and hippocampal neurogenesis were investigated in rats under enriched conditions.
Distribution of serotonin 5-HT1A-binding sites in the brainstem and the hypothalamus, and their roles in 5-HT-induced sleep and ingestive behaviors in rock pigeons (Columba livia)
5-HT1ARs are concentrated in the brainstem 5-HTergic areas and throughout the periventricular hypothalamus, preoptic nuclei and circumventricular organs, which are related to drinking and sleep regulation, but modestly affected c-Fos expression in 5- HTergic neurons.
Behavioral profile and Fos activation of serotonergic and non-serotonergic raphe neurons after central injections of serotonin in the pigeon (Columba livia)
The data indicate that hyperdipsic and hypnogenic effects of ICV 5-HT in pigeons may result from the inhibition of a tonic activity of serotonergic neurons, which is possibly relevant to the control of postprandial behaviors, and that these relationships are shared functional traits of theserotonergic circuits in amniotes.
Serotonergic control of ingestive and post-ingestive behaviors in pigeons (Columba livia): The role of 5-HT1A receptor-mediated central mechanisms
The data indicate that an ongoing, tonic and inhibitory influence of central 5-HT circuits may participate in the control of feeding, drinking and rest behaviors in pigeons during the wake, nibbling diurnal state and suggest that they may represent a conserved, plesiomorphic functional trait of the amniotes brain.
Behavioral and metabolic effects of central injections of orexins/hypocretins in pigeons (Columba livia)
The data substantiate the lack of orexigenic effects of ORXs in avian species, and suggest that an important role in vigilance control may represent a conserved functional attribute of Orexinergic circuits in vertebrates.
Behavioural and electroencephalographic effects of systemic injections of 8-OH-DPAT in the pigeon (Columba livia)
While 5-HT(1a) receptor-mediated mechanisms play crucial roles in ingestive and sleep/waking behaviours in mammals and birds, their action upon these states shows substantial inter-taxon variance.
