Exploring Behavior-Relevant and Disentangled Neural Dynamics with Generative Diffusion Models
Understanding the neural basis of behavior is a fundamental goal in neuroscience. Current research in large-scale neuro-behavioral data analysis often relies on decoding models, which quantify behavioral information in neural data but lack details on behavior encoding. This raises an intriguing scientific question: " how
