Extended Data Fig. 6: Variance in trial-averaged activity explained by PT cell class.
From: Distinct descending motor cortex pathways and their roles in movement
a, Green line: variance of trial-averaged activity explained by increasing numbers of principal components across the population of PTupper neurons (n = 61). Dark green line and 95% confidence interval: expected variance explained by the same number of components for size-matched samples (n = 1,000 repetitions) of simultaneously recorded, unidentified neurons. b, Ratio of variance explained between PTupper neurons and bootstrapped distribution of simultaneously recorded unidentified neurons. Error bars represent s.d. of distribution. c, d, As in a and b, but for PTlower neurons (n = 69). Asterisks denote points significantly greater than unity (P < 0.05, bootstrap).
