A critical review of chronic stress effects on spatial learning and memory
The purpose of this review is to evaluate the effects of chronic stress on hippocampal-dependent function, based primarily upon studies using young, adult male rodents and spatial navigation tasks. Despite this restriction, variability amongst the findings was evident and how or even whether chronic stress influenced spatial ability depended upon the type of task, the […]
Memory of visual and topographical features suggests spatial learning in nautilus (Nautilus pompilius L.)
Previous studies demonstrate that soft-bodied (coleoid) cephalopods are adept at learning and remembering features of their environment, but little is known about their primitive relative, nautilus. Nautilus makes nightly migrations from deep to shallow water along coral reef slopes, covering large areas of varied substrate. Memory of its surroundings may be advantageous, but the nautilus […]
Socio-Spatial Relationships in Dairy Cows
Farm animals may serve as models for evaluating social networks in a controlled environment. We used an automated system to track, at fine temporal and spatial resolution (once per minute, ±50 cm) every individual in six herds of dairy cows (Bos taurus). We then analysed the data using social network analyses. Relationships were based on […]
Measuring chronic social tension in groups of growing pigs using inter-individual distances
Abstract Chronic social stress in pigs compromises immune function, reduces ADG, increases activity and skin lesions and affects feeding behaviour but to different extents in individuals and contemporary groups housed in the same way. Assessing the animals’ perception of chronic social stress is difficult. A large inter-individual distance has been suggested to indicate acute stress […]
Effects of stressors in adolescence on learning and memory in rodent models
This article is part of a Special Issue “Puberty and Adolescence”. Learning and memory is affected by a myriad of factors, including exposure to stressors and the corresponding rise in circulating glucocorticoids. Nevertheless, the effects of stressors depend on the sex, species, the type of stressor used, the duration of exposure, as well as the […]
