Abstract

Recent findings by Chettih et al. (Cell 187: 1922–1935, 2024) from electrophysiological recordings in the hippocampus of black-capped chickadees shed light on the debate about how food-hoarding Parids may remember their cache sites. When birds retrieve caches, a “bar code” is reactivated, which is very similar to the code generated when the same cache was made. The current evidence suggests that this bar code is only triggered after the bird starts to retrieve the cache, and not in anticipation. This finding is more consistent with cued recall than with free recall of cache locations.

Parids中缓存的本质是什么？对Chettih等人的评论。2024

最近，Chettih等人（Cell 187: 1922-1935, 2024）从黑冠山雀海马体的电生理记录中得出的发现，为关于囤积食物的巴黎人如何记住它们的贮藏地点的争论提供了线索。当鸟类获取缓存时，一个“条形码”被重新激活，这与生成相同缓存时生成的代码非常相似。目前的证据表明，这种条形码只有在鸟开始获取食物后才会被触发，而不是在预期中被触发。这一发现与提示记忆比自由记忆更一致。

期刊介绍： Animal Cognition is an interdisciplinary journal offering current research from many disciplines (ethology, behavioral ecology, animal behavior and learning, cognitive sciences, comparative psychology and evolutionary psychology) on all aspects of animal (and human) cognition in an evolutionary framework. Animal Cognition publishes original empirical and theoretical work, reviews, methods papers, short communications and correspondence on the mechanisms and evolution of biologically rooted cognitive-intellectual structures. The journal explores animal time perception and use; causality detection; innate reaction patterns and innate bases of learning; numerical competence and frequency expectancies; symbol use; communication; problem solving, animal thinking and use of tools, and the modularity of the mind.
