It is unclear to what extent individual human annotators within and between different labs agree on the definitions of behaviors, especially the precise timing of behavior onset/offset. Scoring for social behaviors often takes human annotators 3–4× the video’s duration to annotate for long recordings, there is also risk of drops in annotation quality due to drifting annotator attention. A typical study of freely behaving animals can produce tens to hundreds of hours of video that require manual behavioral annotation ( Zelikowsky et al., 2018 Shemesh et al., 2013 Branson et al., 2009). This is usually accomplished via manual scoring of the animals’ actions ( Yang et al., 2011 Silverman et al., 2010 Winslow, 2003). Recent technological advances, such as miniaturized imaging and electrophysiological devices, have enabled the recording of neural activity in freely behaving mice ( Remedios et al., 2017 Li et al., 2017 Falkner et al., 2020)-however, to make sense of the recorded neural activity, it is also necessary to obtain a detailed characterization of the animals’ actions during recording. Gaining insight into brain systems that control these behaviors requires recording and manipulating neural activity while measuring behavior in freely moving animals. The brain evolved to guide survival-related behaviors, which frequently involve interaction with other animals. Together, MARS and BENTO provide an end-to-end pipeline for behavior data extraction and analysis in a package that is user-friendly and easily modifiable. Finally, we introduce the Behavior Ensemble and Neural Trajectory Observatory (BENTO), a graphical user interface for analysis of multimodal neuroscience datasets. We also release the pose and annotation datasets used to train MARS to serve as community benchmarks and resources. We compare MARS’s annotations to human annotations and find that MARS’s pose estimation and behavior classification achieve human-level performance. We introduce the Mouse Action Recognition System (MARS), an automated pipeline for pose estimation and behavior quantification in pairs of freely interacting mice. However, automatically and accurately classifying complex social behaviors remains technically challenging. Recent advances in computer vision enable tracking the pose (posture) of freely behaving animals. This is generally done through manual annotation-a highly time-consuming and tedious process.

Here are the steps you need to take if you want to change your cursor back to the original design by yourself: Select one of the tiles under Change pointer color. Select Adjust mouse & cursor size under Related settings on the right. Select Mouse from the column on the left. The next window will offer options for changing the pointer size and color. In the Window that follows click on “Adjust mouse & cursor size” in the right-side column. Can you change your mouse cursor?Ĭustomize Your Mouse on Windows 10 Search for and click on “Mouse settings” on your computer via the Start button or the Search bar in your taskbar.
