Abstract

Investigating affective experiences in animals is inherently challenging. However, the conditioned place preference (CPP) paradigm offers a valuable method for inferring internal states. Understanding the neural and hormonal mechanisms underlying emotions in animals is crucial for elucidating the biological basis of human emotions. CPP assesses an animal's preference for an environment associated with a rewarding or aversive stimulus. While extensively used to study drug effects, the CPP paradigm has been less frequently applied to investigate the effects of natural stimuli. Furthermore, most studies using this paradigm have been conducted with rodents. This study utilizes the CPP paradigm to investigate the rewarding properties of nursing in lactating rabbits, a unique mammalian behavior that occurs once daily. We found that nursing induced CPP in the lactating doe, which we interpret as a positive affective state—an event fulfilling a motivational drive that occurs only every 24 hours. The results of this study provide valuable insights into the affective state of this species and the neurobiological basis of motivation and reward in a natural context.

哺乳对泌乳兔是有益的

研究动物的情感体验本身就是一项挑战。然而，条件位置偏好（CPP）范式为推断内部状态提供了一种有价值的方法。了解动物情绪的神经和激素机制对于阐明人类情绪的生物学基础至关重要。CPP评估动物对与奖励或厌恶刺激相关的环境的偏好。虽然广泛用于研究药物作用，但CPP范式很少用于研究自然刺激的作用。此外，大多数使用这种范式的研究都是在啮齿动物身上进行的。本研究利用CPP范式来研究哺乳兔的奖励特性，哺乳兔是一种独特的哺乳动物行为，每天发生一次。我们发现，哺乳会诱发哺乳期母鹿的CPP，我们将其解释为一种积极的情感状态——一种每24 小时才发生一次的动机驱动事件。这项研究的结果为这个物种的情感状态和自然环境中动机和奖励的神经生物学基础提供了有价值的见解。

期刊介绍： Behavioural Processes is dedicated to the publication of high-quality original research on animal behaviour from any theoretical perspective. It welcomes contributions that consider animal behaviour from behavioural analytic, cognitive, ethological, ecological and evolutionary points of view. This list is not intended to be exhaustive, and papers that integrate theory and methodology across disciplines are particularly welcome.
