Abstract

In honey bees, appetitive motivation is primarily driven by the needs of the colony rather than individual needs. The regulation of appetitive behavior is achieved through the coordinated action of neuropeptides, hormones and biogenic amines, which integrate multiple signals to ensure appropriate appetitive responses. Dopamine signalling underpins a food-related wanting system that is sensitive to aversive experiences. The short neuropeptide F (sNPF) enhances appetitive responsiveness, food intake and behavioral and neural responsiveness to food-related odorants. Additionally, it facilitates appetitive learning and memory. On the contrary, tachykinin-related peptides (TRPs) inhibit appetitive responses. Physiological changes during the transition to the foraging state lead to distinct patterns of insulin and adipokinetic hormone (AKH) signaling, different from those seen in solitary insects, indicating that social life had significant consequences on the systems controlling appetitive motivation. Overall, studying the neural bases of appetitive behavior in bees reveals unique aspects that arise from their social lifestyle.

当社会决定食物搜寻--蜜蜂食欲动机的神经信号基础
蜜蜂的食欲动机主要受蜂群需求而非个体需求的驱动。食欲行为的调节是通过神经肽、激素和生物胺的协调作用来实现的,它们整合了多种信号,以确保适当的食欲反应。多巴胺信号是与食物有关的欲望系统的基础,该系统对厌恶体验很敏感。短神经肽 F(sNPF)能增强食欲反应、食物摄入量以及对食物相关气味的行为和神经反应。此外,它还能促进食欲学习和记忆。相反,速激肽(TRPs)会抑制食欲反应。在过渡到觅食状态期间,生理变化导致了胰岛素和促脂肪激素(AKH)信号的独特模式,这与在独居昆虫中看到的模式不同,表明社会生活对控制食欲动机的系统有重大影响。总之,对蜜蜂食欲行为神经基础的研究揭示了其社会生活方式所产生的独特方面。

期刊介绍: Current Opinion in Neurobiology publishes short annotated reviews by leading experts on recent developments in the field of neurobiology. These experts write short reviews describing recent discoveries in this field (in the past 2-5 years), as well as highlighting select individual papers of particular significance. The journal is thus an important resource allowing researchers and educators to quickly gain an overview and rich understanding of complex and current issues in the field of Neurobiology. The journal takes a unique and valuable approach in focusing each special issue around a topic of scientific and/or societal interest, and then bringing together leading international experts studying that topic, embracing diverse methodologies and perspectives. Journal Content: The journal consists of 6 issues per year, covering 8 recurring topics every other year in the following categories: -Neurobiology of Disease- Neurobiology of Behavior- Cellular Neuroscience- Systems Neuroscience- Developmental Neuroscience- Neurobiology of Learning and Plasticity- Molecular Neuroscience- Computational Neuroscience
