Fig. S4.

Oscillations induced by optogenetic stimulation of SChIs upon infusion with ACSF in the striatum (i) as well as the superficial (ii), middle (iii), and deep (iv) M1 layers. (A) Preinfusion spectrogram. (B) Postinfusion spectrogram. (C) Bar plot comparing laser-induced oscillation power normalized to the prelaser baseline during preinfusion and postinfusion period. Laser stimulation was effective at inducing beta and gamma oscillations. There were no significant differences between preinfusion and postinfusion in striatum. The error bars represent the 95% confidence intervals. (*P < 0.05; ***P < 0.001; nonparametric paired signed-rank test). Beta, 15–30 Hz; low gamma, 30–60 Hz; high gamma, 60–100 Hz.
