a We used neural decoders to detect right foot-strike and foot-off gait events from neural population activity in the left hemisphere. The decoders were calibrated on the dataset from recordings during walking along the corridor, and were then tested on datasets from the four remaining tasks to evaluate decoding accuracy, as measured by the F-score. We applied this decoding analysis to datasets containing all neural activity from a cortical region (black dot), and to this dataset with one or more leading task-dependent (light green dots) or task-independent (dark green dots) modes removed. b Plots show the decoding accuracy for datasets containing all neural activity (black) or the same datasets with leading task-dependent (light green) or task-independent modes (dark green) removed. Dots show data from individual sessions (n = 7). Lines show the mean across sessions. Error bars: s.e.m. Source data are provided as a Source Data file.
