Fig. 4. Stability of state-dependent changes in neural properties during a session.

a. Traces show the preferred direction and modulation depth for a moving window of trials (window of 16 trials) for a direct unit. Each segment is color coded and labeled (MC₁, brain control or BC, MC₂). b. Average of multiple direct units from both animals. To illustrate the time course at the population level, the respective mean MC₁ value was subtracted from each individual trace and the absolute value was used for the average. n=number of units included in the average. Each plot shows the mean (thick line) ± 2 s.e.m. (thin line). c,d. Individual example and average responses of indirect units. Arranged as in a,b.
