Light during incubation can influence embryonic and postembryonic development of chickens, but the underlying mechanisms are poorly understood. Previous studies have demonstrated that red blue lights had opposite effects on melatonin biosynthesis; light results in highest lowest amplitude daily rhythm. Therefore, this study, we investigated if exposure to monochromatic (632 nm) (463 differently...

Recently in our laboratory we found that DTG (sigma receptor agonist 1,3-di-o-tolyl-guanidine) sub-chronic administration reduced the hyperlocomotor activity and reversed the neuronal hypotrophy in the prefrontal cortex, amygdala and nucleus accumbens, generated in rats with neonatal ventral hippocampus lesion (nVHL). We also observed that DTG reversed some of the behavioral and neuromorphologi...
