EthoTrace:在统一分析框架中从行为标注到神经动态
EthoTrace: from behaviour to neural dynamics in a unified analysis framework
依据摘要,作者开发了 EthoTrace,一个无需安装、服务器或网络访问、可在桌面浏览器中运行的单文件 HTML 工具,把行为标注与钙信号分析串到同一会话中。行为在与 ΔF/F 轨迹共享的时间轴上标注,信号按声明的基线约定校正与缩放,单次行为片段保留在行为情境中可核查,重复片段对齐时不填充缺失数据。
Understanding how neural populations support natural behaviour requires knowing what a population does while an animal performs a specific, self-initiated action. For responses evoked by an experimenter-delivered stimulus, the signal can be aligned by the trigger itself, and no behavioural scoring is needed to define the event. Complex behaviours such as parental care and social interaction provide no such trigger. They are defined from the video record, usually offline and post hoc, and are conventionally scored in one program and exported to another for analysis. In this study we developed EthoTrace, a single self-contained HTML file that runs in a desktop browser without installation, server or network access and carries a session from behaviour and calcium signal through to the statistical comparison. Behaviour is annotated on a timeline shared with the {Delta}F/F trace, the signal is corrected and scaled under a stated baseline convention, single bouts stay inspectable in their behavioural context, and repeated bouts are aligned without filling absent data. We demonstrate the complete workflow on a parenting behaviour experiment, in which behaviour was scored and the photometry signal analysed in a single session folder. We expect EthoTrace to facilitate integrative analysis in neuroscience, where behavioural observation and fiber photometry signals are interpreted together.
