Figure 9.

The selected θ/β-γ transition pattern is restricted to the PrL cortex. A, LFPs recorded simultaneously in six different cortical and subcortical sites during a sequence of the touch-screen operant conditioning task. B, Analysis of coherence between the θ/β-γ transition patterns recorded in the PrL cortex and the other five recording sites for the θ, β, low-γ, and high-γ bands. Note that the highest coherence (0.62, see color scale) was between the PrL and the M1 area of the motor cortex for the high-γ band. C, Coherence profiles for the activity of θ, β, low-γ, and high-γ bands in the PrL cortex and the other five recording sites during the appearance of the θ/β-γ transition pattern. D, Maps of time–frequency coherence between the Pre, Pattern, and Post periods for LFPs recorded in the PrL cortex and the other five recording sites. Illustrated maps correspond to the average of 100 samples collected from five different animals. Note the high coherence between recordings collected from PrL and M1 recording sites, mostly for the Pre and Post periods.
