Figure 3. Coherence of oscillatory activity in the cortico-striato-pallidal network in parkinsonian non-human primates.

Figure 3.

(NHPs). (A) Increased coherence of LFPs (upper graph) between the motor cortex and the striatum (Va, n=13 recordings) similarly shown at both 8–13 Hz and 13–20 Hz frequency bands (bottom graph). (B) Increased coherence of LFPs also between the striatum and the GPi (Va, n=11 recordings) at both frequency bands. These results demonstrate the presence of augmented oscillatory activity at 8–20 Hz in the basal ganglia circuits after dopamine loss. Thick and thin lines represent mean and standard error of mean, respectively. MCx=motor cortex; STR=striatum; GPi=globus pallidus internus. The black horizontal lines and white circles in the box plots represent the mean and median values, respectively.
