(A) Spike-triggered average (STA) of membrane potential for the spiking cell (dark gray) and the paired cell (light gray) during spontaneous activity (n=20). Traces are means across all pairs. Shaded regions represent standard error. Note that the spike in the top trace is truncated for display.
(B) Same as (A) but for visually-evoked activity (n=20).
(C) Band-pass filtered STA (15–40 Hz) of membrane potential for paired cell during visually-evoked (blue) and spontaneous (gray) activity (n=20).
