Returning to home cage serves as an effective reward for maze learning in rats

This study examined the effectiveness in rats of ‘returning to home cage' as a reward for learning a Lashley III maze. Rats could return to their home cage directly (Direct HC group) or they could be removed manually by an...

Effects of combined pre- and post-natal enrichment on anxiety-like, social, and cognitive behaviours in juvenile and adult rat offspring

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 progeny were co-housed through gestation...

Emission of 22 kHz vocalizations in rats as an evolutionary equivalent of human crying: Relationship to depression

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 to answer the question whether...

Distinct environmental enrichment protocols reduce anxiety but differentially modulate pain sensitivity in rats

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 peripheral pain sensitivity of male...

Music exposure attenuates anxiety- and depression-like behaviors and increases hippocampal spine density in male rats

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 and behavior of experimental animals....

Using subcuticular stitching in rats to replace skin closure clips as a refinement

Skin closure clips are widely used within the University of Edinburgh to close incision sites for various procedures in both rats and mice. In rats the skin closure clips very often come out as a result of cage mates biting...

The effects of cage color and light intensity on rat affect during heterospecific play

Environmental enrichment provides physiological and emotional benefits to laboratory rodents. Red tinted shelters are a common enrichment found in laboratories that provide rodents with a hiding space shielded from bright light. Red tinting alters the light's spectral make-up which reduces...

Report of the Enrichment; Awareness and Uptake Workshop 2018 on 26th June at College Court, Leicester

The point of the session was to have a collaborative discussion about environmental enrichment. The organisers wanted to know people's experiences with enrichment, the barriers they have faced, if they have overcome any, and also to share some of their...

Humanely ending the life of animals: Research priorities to identify alternatives to carbon dioxide
