Seeing through the eyes of a mouse by decoding its brainsignals epfl_en nature
Rooted in mathematics, the novel machine learning algorithm is called CEBRA , and learns the hidden structure in the neural code.
What information the CEBRA learns from the raw neural data can be tested after training by decoding—a method that is used for brain-machine-interfaces —and they've shown they can decode from the model what a mouse sees while it watches a movie. But CEBRA is not limited to visual cortex neurons, or even brain data. Their study also shows it can be used to predict the movements of the arm in primates, and to reconstruct the positions of rats as they freely run around an arena.
can be arrange, or embedded, in a lower-dimensional space called a latent space, so that similar data points are close together and more-different data points are further apart," explains Mathis.
