Fig. 4. Cerebellar-mediated facilitation of learning depends on task feedback interval.

Fig. 4

a Dysmetria score during learning for short (light red), medium (red) and long (dark red) levels of feedback interval for the simple and online LD visuomotor tasks and both models cRNN (gray) and ccRNN (orange). Degrees of redness b Difference in dysmetria score between ccRNN and cRNN for varying degrees of task feedback intervals (ns denotes not significant: p = 0.122 (30%), p = 0.268 (40%), p = 0.142 (50%) for simple LD and p = 0.444 (36%), p = 0.209 (46%) for online LD). Degrees of red in arrows indicate the respective interval as in (a) while the white arrow indicates the feedback interval used in Figs. 2 and 3. Task feedback interval is given as a percentage of the total task time. c Difference in training error between cRNN and ccRNN for varying degrees of task feedback interval (ns for simple LD: p = 0.099). d Normalised training error integrated over learning (left) and dysmetria score at end of learning (right) of ccRNN with respect to cRNN for varying degrees of cerebral feedback horizons and task feedback intervals (left: simple LD task; right: online LD task). **p < 0.01, ***p < 0.001, ****p < 0.0001 (two-sided paired t-test between cRNN and ccRNN). Error bars represent mean ± SEM across 10 different initial conditions. Source data are provided as a Source Data file.
