Figure 2. Variability of behavioral dimensions evolves independently as animals learn a motor task.
(A, B) Frequency and duration of lever-press sequences (C–F) Variability, measured as the variance and Fano factor, for sequence frequency and sequence duration. (G–H) Fano factor of both frequency and duration, normalized to the first session, for the frequency and control tasks. Shaded areas correspond to mean ± SEM.
Figure 2—figure supplement 1. Significant correlation between variability of number of presses and duration, but not between variability of frequency and duration.
Scatter plots of the paired values, variances and Fano factors, for frequency/duration and number of presses/duration. Each point corresponds to one session of one individual animal, with darker colors depicting later sessions. Line corresponds to the best linear fit of all the data, with the correspondent R2 value.
