Abstract:
Growing evidence reveals notable phenotypic plasticity in cognition among teleost fishes. One compelling example is the positive impact of enriched environments on learning performance. Most studies on this effect have focused on juvenile or later life stages, potentially overlooking the importance of early life plasticity. To address this gap, we investigated whether cognitive plasticity in response to environmental factors emerges during the larval stage in zebrafish. Our findings indicate that larvae exposed to an enriched environment after hatching exhibited enhanced habituation learning performance compared to their counterparts raised in a barren environment. This work underscores the presence of developmental phenotypic plasticity in cognition among teleost fish, extending its influence to the very earliest stages of an individual\'s life.
摘要:
越来越多的证据表明,硬骨鱼的认知具有明显的表型可塑性。一个令人信服的例子是丰富的环境对学习表现的积极影响。大多数关于这种影响的研究都集中在青少年或以后的生活阶段,可能忽视早期生命可塑性的重要性。为了解决这个差距,我们调查了斑马鱼幼体阶段对环境因素的认知可塑性。我们的发现表明,与在贫瘠环境中饲养的幼虫相比,孵化后暴露于丰富环境的幼虫表现出增强的习惯性学习性能。这项工作强调了硬骨鱼认知中发育表型可塑性的存在,将其影响扩展到个人生命的最早期阶段。
