The rearing environment of layer chicks can differ greatly in degree complexity. With the industry moving towards cage-free housing systems, greater demands are placed on birds’ cognitive abilities order for them to find resources such as food, water and nest-boxes. Because early environmental complexity influence cognition, we aimed at increasing our knowledge how two different environments af...

Abstract Introduction Increased attention to sleep-related stimuli (i.e., “sleep-related attentional bias”) may contribute the persistence of insomnia symptoms. Despite high prevalence disorder in older adults, studies investigating this phenomenon population are lacking. Additionally, it is unclear whether bias occurs only for visual or more broadly, such as auditory stimuli. This study examin...

Much evidence shows that the hippocampus and striatum play roles as important neural substrates for spatial/place and cued/response learning, respectively. This experiment was conducted to investigate the engagement of the striatum in cued/response learning. The engagement of the striatum was assessed after either place or cue training by determining levels of cAMP response element-binding prot...
