Application of CEBRA-Behavior: A Case Study

Title: Application of CEBRA-Behavior to Rat Hippocampus Data: Uncovering Neural Dynamics during Adaptive Behaviors

Introduction
Mapping behavioral actions to neural activity is a fundamental goal of neuroscience. With the advent of advanced recording techniques, there is a growing interest in modeling neural dynamics during adaptive behaviors to understand underlying neural representations. To address the need for non-linear techniques that can leverage joint behavioral and neural data, we introduce CEBRA, a novel encoding method that produces consistent and high-performance latent spaces.

Methodology and Results
CEBRA utilizes behavioral and neural data in a supervised or self-supervised manner to generate latent spaces. It achieves consistency by using it as a metric to uncover meaningful differences and enables accurate decoding. In this case study, we applied CEBRA to rat hippocampus data (Grosmark and Buzsáki, 2016) and obtained a median absolute error of 5cm. The total track length was 160cm (details available in the provided pre-print).

Validation and Utility
We validated the accuracy of CEBRA and demonstrated its utility for calcium and electrophysiology datasets across sensory and motor tasks. It is applicable to simple or complex behaviors and can be used with single or multi-session datasets, whether for hypothesis testing or label-free analysis. Furthermore, CEBRA is capable of mapping space, uncovering complex kinematic features, and producing consistent latent spaces across different data types such as 2-photon and Neuropixels recordings. Additionally, CEBRA enables rapid and high-accuracy decoding of natural movies from the visual cortex.

Conclusion and Further Information
CEBRA fills the gap for non-linear encoding techniques that leverage joint behavior and neural data to uncover neural dynamics. Its consistent and high-performance latent spaces make it a valuable tool in neuroscience research. The pre-print of our study can be accessed on arxiv.org/abs/2204.00673.
