摘　　要：家犬(Canis lupus familiaris)与人类社会生态高度融合,已成为人类解析认知进化理论、进行比较认知研究、开展人类认知功能障碍性疾病研究的一种自然模型动物。功能性磁共振成像(functional magnetic resonance imaging,fMRI)是一种非侵入式、安全的能反映生物体大脑神经活动时空分布的神经影像学技术,近年来被应用于家犬行为认知特征神经机制的研究。本文简介了fMRI技术;概述了部分研究者使用视觉、嗅觉、听觉等不同的实验范式对家犬大脑开展fMRI,定位不同实验范式下被激活的大脑功能区,从而揭示家犬认知的神经机制;总结了fMRI技术在犬认知研究中技术和方法上的挑战。以期为国内开展家犬等动物认知研究者提供新的技术方法。Domestic dogs are highly integrated into human society and ecology,and have become a natural model animal for analyzing cognitive evolution theory,conducting comparative cognitive research,and conducting human cognitive dysfunction disease research.Functional magnetic resonance imaging(fMRI)is a non-invasive and safe neuroimaging technique that can reveal the temporal and spatial distribution of biological brain neural activities.In recent years,fMRI has been used to study the neural mechanisms of behavioral cognitive characteristics in domestic dogs.This paper provides an introduction to the fMRI technique.We reveal how the neural mechanisms of dog cognition were studied using fMRI of dog brains to locate the activated functional brain areas under different experimental paradigms,such as vision,smell,and hearing.The technical and method ological challenges of fMRI in canine cognitive research are also summarized.This paper provides a theoretical basis and reference for researchers who carry out cognition studies on domestic dogs and other animals.
