Extended Data Fig. 6: Information regarding the side light stimulus in SC neurons.

a, SC population decoding performance (mean ± s.d.) for linear classification of correct Pro versus Anti trials (task, red line), Go-Left versus Go-Right trials (choice, blue line), and Left-Light versus Right-Light trials (light stimulus, black line). Compared to the early and strong choice information in the SC population, linearly decodable information related to the light stimulus appeared later and weaker, suggesting that information being received by deep SC layer neurons about which side the Light is on is combined nonlinearly and very rapidly with context information, to produce early, linearly decodable information about choice. b, Matrix of light stimulus (left side light/ right side light) selectivity for the SC neural population, similar to Fig. 1e.
