Possible network for theta-band synchronization. A, Sustained rhythmic firing at 4 Hz in L3 PCs generated by recurrent network among L3 PCs in the presence of capsaicin. A short-lived rhythmic firing at 8 Hz occurs alternately in adjacent L5 PCs during the sustained rhythmic firing in L3 PCs. Such network oscillations propagate from Gu-I to Au-I. Red and gray represent the present and future (a) or the present and past (b) activities, respectively. B, Enhancement of recurrent network synchronization among L3 PCs by coapplication of PMA and capsaicin engages L5 PCs in the same theta-band synchronization after a short-lived 8 Hz firing. Red and gray represent the present and future (a) or the present and past (b) activities, respectively.
