Cebra

What is Cebra?

CEBRA is a machine-learning method designed to compress time series data effectively, revealing hidden structures in data variability. It excels in analyzing both behavioral and neural data simultaneously, demonstrating the ability to decode activity from the visual cortex of the mouse brain to reconstruct viewed videos. The method employs non-linear techniques that merge behavioral and neural data, offering deep insights into brain activity beyond traditional linear models. CEBRA's versatility allows it to be applied to diverse datasets, including calcium imaging and electrophysiology, across various sensory and motor tasks. One of its key features is label-free decoding, enabling the reconstruction of complex kinematic features and visual experiences without external labeling. Additionally, CEBRA supports multi-session analysis, facilitating the exploration of consistent latent spaces for robust hypothesis testing, and enables rapid, high-accuracy decoding of natural movies from the visual cortex to enhance the understanding of neural representation.
