Mora-Gallegos, A., Fornaguera, J. 2019. The effects of environmental enrichment and social isolation and their reversion on anxiety and fear conditioning. Behavioural Processes 158, 59-69.

Animal models of fear and anxiety provide important insight into anxiety-related symptoms in humans. Environmental physical conditions and social contact influence behavior and brain plasticity particularly at early developmental stages and have long lasting effects...

Yao, L., Li, Y., Qian, Z. et al. 2019. Loss of control over mild aversive events produces significant helplessness in mice. Behavioural Brain Research 376, 112173.

This article is about the importance of giving mice control over what happens to them. Most of the pathophysiology of depression are still unknown because of its numerous disease states of distinct etiology and pathogenesis...

Papadakakis, A., Sidiropoulou, K., Panagis, G. 2019. Music exposure attenuates anxiety- and depression-like behaviors and increases hippocampal spine density in male rats. Behavioural Brain Research 372, 112023.

Epidemiological and clinical studies suggest that early-life stress (ELS) may lead to the development of mental disorders in adulthood. Maternal separation (MS) is a valid animal model of ELS that produces detrimental effects on brain...

Estrada, C., Cuenca, L., Cano-Fernandez, L. et al. 2019. Voluntary exercise reduces plasma cortisol levels and improves transitory memory impairment in young and aged Octodon degus. Behavioural Brain Research 373, 112066.

Sleep deprivation (SD) has been reported to induce transient cognitive impairment in functional domains commonly affected in dementia, including memory. Indeed, sleep disturbance has been proposed as an early marker for Alzheimer’s disease (AD). SD...

Liang, F., Yang, S., Zhang, Y. et al. 2019. Social housing promotes cognitive function through enhancing synaptic plasticity in APP/PS1 mice. Behavioural Brain Research 368, 111910.

Previous studies have shown that loneliness increases the risk of AD (Alzheimer’s disease) onset, while active and frequent social housing delays the onset of cognitive impairment. The mechanism of how this occurs remains unclear. In...

Faggionato Kimura, L., Mattaraia, V. G. M., Picolo, G. 2019. Distinct environmental enrichment protocols reduce anxiety but differentially modulate pain sensitivity in rats. Behavioural Brain Research 364, 442-446.

Environmental enrichment (EE) can alter anxiety as well as perception of nociceptive stimuli, suggesting a relationship between well-being and analgesia. Considering that, we aimed to evaluate the influence of different EE types on anxiety and...

Brudzynski, S. M. 2019. Emission of 22 kHz vocalizations in rats as an evolutionary equivalent of human crying: Relationship to depression. Behavioural Brain Research 363, 1-12.

There is no clear relationship between crying and depression based on human neuropsychiatric observations. This situation originates from lack of suitable animal models of human crying. In the present article, an attempt will be made...

Sparling, J. E., Baker, S. L., Bielajew, C. 2018. Effects of combined pre- and post-natal enrichment on anxiety-like, social, and cognitive behaviours in juvenile and adult rat offspring. Behavioural Brain Research 353, 40-50.

The pre- and post-natal periods are characterized by unrivalled growth and are sensitive to environmental changes. A correctly stimulating early environment is essential for developing natural behaviors and maintaining affective wellness. Five litters of rat...

Gurney, L. 2019. In-vivo imaging at NIBSC and how we use it to promote the 3Rs. Animal Technology and Welfare 18(2), 143-144. (IAT Congress 2018 Poster Presentation)

In-vivo imaging is a revolutionary technology offering a powerful tool for constructing studies involving mice. In the Biological Services Department (BSD) at NIBSC, the IVIS® Spectrum In Vivo System model is used to perform our...

Zvarev, C., Baker, S., Patel, D. 2019. Animal handling in containment. Animal Technology and Welfare 18(2), 140-142. (IAT Congress 2018 Poster Presentation)

As Animal Technologists we are constantly looking at refining and enriching the environmental conditions of all our animals to give them both physical exercise and mental stimulation regardless of their size. However, animals can still...
