Neural Population Dynamics during Reaching Are Better Explained by a Dynamical System than Representational Tuning

Number of neurons and conditions required for statistically significant rotations.
The CMPT was carried out (500 repetitions) for many subsets of example PMd/M1 data including from 10–120 neurons and 2–20 conditions. (a) Map of p-values for the rotational goodness-of-fit ratio (RGR: ). (b) Map of effect size (difference between observed RGR and mean of permuted distribution, divided by the SD of the permuted distribution). For every permutation, random neurons and conditions were drawn from the example set. Contours show the 0.05 and 0.01 significance levels.
