Geometric morphometrics for the study of facial expression of pain in common marmosets

这项研究旨在量化常见绒猴在常规疼痛过程中面部表情的变化，并对照传统的疼痛相关行为来验证这些变化。在2022财年，我继续对常见绒猴的面部表情和一般行为进行初步分析。我预计在今年夏天完成全面的分析。我还完成了一个单独但相关的项目，研究普通绒猴对视觉社交线索的荷尔蒙和行为反应。此外，我在京都大学、CIEA和英国纽卡斯尔大学之间建立了一个新的合作伙伴关系，对绒猴行为和面部表情进行自动评分。

This study aims to quantify changes in facial expression in common marmosets in relation to a routine painful procedure, and validate these changes against traditional pain-related behaviours. In FY2022, I continued to build upon my preliminary analysis of the facial expressions and general behaviour of common marmosets. I expect to complete the full analysis this summer. I also completed work on a separate, but related, project on hormonal and behavioural responses to visual social cues in common marmosets. In addition, I established a new collaboration between Kyoto University, CIEA, and the University of Newcastle, UK, on the automated scoring of marmoset behaviour and facial expressions.
