Behavioural characterisation of chronic unpredictable stress based on ethologically relevant paradigms in rats
The chronic unpredictable stress (CUS) paradigm is extensively used in preclinical research. However, CUS exhibits translational inconsistencies, some of them resulting from the use of adult rodents, despite the evidence ...
Effects of environmental enrichment and social isolation on sucrose consumption and preference: Associations with depressive-like behavior and ventral striatum dopamine
Little attention has been directed towards environmental control of sensitivity to natural reward and its possible relationship with other motivated behaviors, besides the well-known effects of environmental enrichment and ...
A detailed analysis of open-field habituation and behavioral and neurochemical antidepressant-like effects in postweaning enriched rats
Our previous work has shown that male Sprague–Dawley rats reared in social isolation, standard housing and environmental enrichment differ in their spontaneous open-field activity and in some neurobehavioral depressive-like ...
Age-dependent effects of environmental enrichment on spatial memory and neurochemistry
Although aging and environmental stimulation are well-known to affect cognitive abilities, the question of whether aging effects can be distinguished in already-mature adult rats has not been fully addressed. In the ...
Factor analysis of Forced Swimming test, Sucrose Preference test and Open Field test on enriched, social and isolated reared rats
Developmental and social factors are known to play a crucial role in the pathogenesis of affective disorders. Although it has been demonstrated that early life aversive experiences can be a risk factor in the development ...
The effect of chronic fluoxetine on social isolation-induced changes on sucrose consumption, immobility behavior, and on serotonin and dopamine function in hippocampus and ventral striatum
This study examined the effect of fluoxetine, a selective serotonin (5-HT) reuptake inhibitor, on isolation-induced changes on sucrose consumption and preference, spontaneous open-field activity, forced swimming behavior, ...
Differential effect of environment enrichment and social isolation on depressive-like behavior, spontaneous activity and serotonin and norepinephrine concentration in prefrontal cortex and ventral striatum
Dawley rats were reared from weaning in either social isolation, standard laboratory conditions, or environmental enrichment. Open-field activity was assessed at postnatal days 37, 65, 93 and 107 and 1 h before the last ...
Sub-chronic administration of St. John’s wort reverses anxiety- and depressive-like behaviors induced by two different protocols of chronic stress
La administración sub-crónica de hierba de San Juan revierte las conductas de ansiedad y depresión inducidas por dos protocolos distintos de estrés crónico
Introduction. St. John’s wort (Hypericum perforatum, HP) is one of the most used herbal medicines. Here we investigated the putative antidepressive- and anxiolytic-like effects of HP, by using a well-validated rat model ...
