Distribution and characterization of doublecortin-expressing cells and fibers in the brain of the adult pigeon (Columba livia)
TLDR
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.
Stress-induced core temperature changes in pigeons (Columba livia)
TLDR
The present data indicated that stress-induced changes in Tc may be a consistent and reliable physiological parameter of stress but that they may also show stressor type-, direction- and species-specific attributes.
Defensive behaviors and prosencephalic neurogenesis in pigeons (Columba livia) are affected by environmental enrichment in adulthood
TLDR
Enriched environment data suggest that enrichment favored behavioral inhibition and neurogenesis in the adult pigeons through different, parallel mechanisms.
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)
TLDR
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.
The mesencephalic GCt–ICo complex and tonic immobility in pigeons (Columba livia): a c-Fos study
TLDR
The data suggest that inescapable threatening stimuli such as TI may recruit neurons in discrete areas of ICo–GCt complex, deep tectal layer and in ascending auditory circuits that may control the expression of defensive behaviors in pigeons.
Antidepressant and pro-neurogenic effects of agmatine in a mouse model of stress induced by chronic exposure to corticosterone
TLDR
The results suggest that the increase in hippocampal proliferation induced by agmatine may contribute, at least in part, to the antidepressant‐like response of this compound in this mouse model of stress induced by chronic exposure to corticosterone.
Expression of aggressiveness modulates mesencephalic c-fos activation during a social interaction test in Japanese quail (Coturnix japonica)
TLDR
Findings suggest that mesencephalic activation is involved when males are actively expressing aggressive behaviors, regardless of both the environmental stimuli provided during the birds' rearing and the potentially stressful stimuli during the SI trial.
Sexually dimorphic responses of rats to fluoxetine in the forced swimming test are unrelated to the function of the serotonin transporter in the brain
TLDR
Responses of rats responded to the chronic treatment with fluoxetine in a sexually dimorphic fashion during the rFST despite the functioning of SERT in their brains remaining equally unchanged, suggesting that sexuallyDimorphic responses to fluoxettine in rF ST may be unrelated to the function of Sert in rat brains.
Intrathecally injected tramadol reduces articular incapacitation and edema in a rat model of lipopolysaccharide (LPS)-induced reactive arthritis.
TLDR
Spinal NKCC1 cotransporter and peptidergic peripheral afferents seem to be important for the analgesic and antiedematogenic effects of tramadol, as well as μ-opioid receptor.
Combining Animal Welfare With Experimental Rigor to Improve Reproducibility in Behavioral Neuroscience
TLDR
This research attacked the mode of reinforcement learning using a probabilistic approach and found that simple and efficient methods such as reinforcement learning and reinforcement learning can be implemented and improve the quality of human interaction with animals.
