FIGURE 3.
Variability of speed-theta measurements (A) Examples of speed-theta Pearson correlation coefficients (r) and slopes for theta power (left) and frequency (right) in two recording sessions (same CTR animal). Each dot reprephasesents a 0.4 s sample (a sliding window was used). (B) Histograms showing the distribution of slopes (left) and correlation coefficients (right) for speed-theta power (top) and frequency (bottom) in recorded sessions. Note that slopes vary to a large extent for both speed-power and speed-frequency measurements. In contrast to speed-theta power, speed-theta frequency slopes are lower in TLE than in CTR. CTR: Control, TLE: Temporal Lobe Epilpesy. [Color figure can be viewed in the online issue, which is available at wileyonlinelibrary.com.]
