Fig. 6: Distinct neuronal codes during sensorimotor transformation.

a Information (expressed as time-resolved % explained variance; solid lines) about factors target number, instruction stimulus protocol, and their interaction carried by the neuron population across time. Dotted lines show percent explained variance for shuffled trial labels, shaded areas the SEM over resamples. b Time-resolved SVM classifier performance. The solid line shows mean accuracy of classifier performance at each point in time during the trial (the mean diagonal accuracy values derived from the cross-temporal confusion matrix shown in c, the purple shaded area shows the SEM. The gray shaded area marks the distribution of shuffled label classifier performance (5th to 95th percentile), whereas the dashed line shows the chance level for 5 classes. c Cross-temporal SVM classifier performance. Mean accuracy is color coded on the two-dimensional matrix, where training time bins are ordered along the y-axis, and testing time bins along the x-axis (temporally aligned to a and b). Straight dotted lines mark the onset of the instruction stimulus period and straight dashed lines indicate the start and the end of the motor planning period. The area outlined by the thick contour line corresponds to the temporal cluster of time bins significantly above chance level (~25%; cluster permutation test, see Methods for details). Dashed contour lines indicate different levels of accuracy (35–65% in steps of 10%). Source data are provided as a Source Data file.
