The precision of primate visually guided reaching likely evolved to meet the many challenges faced by living in arboreal environments, yet much of what we know about the underlying primate brain organization derives from a set of highly constrained experimental paradigms. Here we review the role of vision to guide natural reach-to-grasp movements in marmoset monkey prey capture to illustrate the breadth and diversity of these behaviors in ethological contexts, the fast predictive nature of these movements [1,2], and the advantages of this particular primate model to investigate the underlying neural mechanisms in more naturalistic contexts [3]. In addition to their amenability to freely-moving neural recording methods for investigating the neural basis of dynamic ethological behaviors [4,5], marmosets have a smooth neocortical surface that facilitates imaging and array recordings [6,7] in all areas in the primate fronto-parietal network [8,9]. Together, this model organism offers novel opportunities to study the real-world interplay between primate vision and reach-to-grasp dynamics using ethologically motivated neuroscientific experimental designs.
灵长类动物视觉引导的伸手抓握的精确性可能是为了应对生活在树木环境中所面临的诸多挑战而进化而来的，但我们对潜在灵长类大脑组织的了解主要来自于一系列高度受限的实验范式。在这里，我们回顾了灵长类动物视觉在引导卷尾猴捕食猎物时的自然伸手抓握运动中的作用，以说明这些行为在生态背景下的广泛多样性、这些运动的快速预测性质[1,2]，以及这种特定灵长类模型在更自然的环境中研究潜在神经机制的优势[3]。除了它们适合用于研究动态生态行为神经基础的自由移动神经记录方法[4,5]之外，狨猴的光滑新皮质表面还便于在灵长类动物额顶网络的所有区域进行成像和阵列记录[6,7] [8,9]。总之，这种模式生物为使用基于生态的神经科学实验设计研究灵长类动物视觉和伸手抓握动态之间的真实世界相互作用提供了新的机会。
