Modulation of the CC by gamma depended on distance from the CS and training. A, To measure the degree of modulation, we calculated the resultant vector of the CC strength across gamma phase during high-amplitude gamma. We have plotted the values during the CS period. On average, NEAR pairs exhibited greater gamma modulation of their CC than FAR pairs. B, Comparing the early and late conditioning trials of session 1 showed that NEAR sites increased the depth of their modulation within the first session, whereas FAR sites did not.
