Effect of neural channel MD on decoding performance. (a) Relation of MD to open-loop decoding correlation of true computer cursor velocity with velocity estimate obtained by decoding each neural channel individually. Shaded region: 95% CI of chance-level decoding correlation. (b) Improvement in decoding correlation with increasing channel subset size chosen using the specified scheme. (c) Normalized BIC as a function of channel subset size chosen by MD. Red circle: optimal subset size with lowest BIC.
