Abnormal theta oscillations were observed in tetanus toxin injected rats. (A) 5-second LFP traces from a control and tetanus toxin injected rat during walking and exploring epochs. (B) Mean ± SD of normalized power spectral densities (nPSDs) from 8 control and tetanus toxin injected rats (Details on PSD computations is provided in the methods section). (C) nPSD (PSD normalized with respect to the maximum power across all frequency bins used for computing the PSD) from one tetanus toxin injected rat recorded from 4 hours post surgery to 30 days post surgery.
