Figure 6. Effect of Fast Inhibition and LN Spike Adaptation for PN Responses.

Figure 6

(A) Blocking LN-LN GABAA inhibition.

(A1) Average PN activity (field potential).

(A2) PN responses for the two different stimuli presented in Figures 4A and 4B. Most of the PNs were now phase-locked with the field potential during the whole trial, reducing the discriminability of PN responses for similar stimuli.

(B) Blocking Ca2+-dependent K+ current in LNs.

(B1) Average PN activity shows oscillations at higher frequency (about 30 Hz).

(B2) PN responses for the two different stimuli presented in Figures 4A and 4B. Now PN synchronization (or its absence) usually endured throughout the whole stimulus duration.
