1. Removal of the PNNs affect LFP oscillations during spontaneous activity, but not during stimulus-evoked activity.
Removal of the PNNs affect LFP oscillations during spontaneous activity, but not during stimulus-evoked activity. A, Example of LFP recording (left) from one session aligned with stimulus onset (0 s) and the respective frequency spectrogram of the same recording (right). B, Time periods with gamma oscillations (gamma events) were not different in chABC-treated animals, neither events per unit time nor gamma event power. C, During spontaneous activity, the chABC-treated rats showed significantly stronger oscillations compared with controls, both in the theta (7–10 Hz) and low-gamma (30–40 Hz) range of the LFP (p = for 7–10 Hz and p = for 30–40 Hz; n = 23 sessions from 3 rats in each group). During visual stimulation, however, we found no differences between groups. Data are shown as mean ± SEM and were analyzed by Student's t test.
