Before revision:  Here we discuss how capturing the postures of animals over time is a key step in transforming videos into lower dimensional representations of behavior. We envision that the fast-paced development of new deep learning tools will rapidly change the landscape of realizable real-world neuroscience experiments .
After revision:  Here we discuss how capturing the postures of animals - pose estimation - has been rapidly advancing with new deep learning methods. While challenges still remain, we envision that the fast-paced development of new deep learning tools will rapidly change the landscape of realizable real-world neuroscience experiments .
