Fig. 7.

The effect of synfire chain switching realized by structured cross-inhibition on collective signals. (a) Spiking activity of a reduced network with synfire chain competition, connected as 1→2,7 and 2,7→1. Activity of 10% of the neurons is shown. (b) Firing rate (black), average membrane potential (red) and approximated LFP (blue; arbitrary units) calculated from activity in the reduced network. Arrows indicate signatures of synfire chain switching in the collective signals. (c, d) As in (a, b) but without synfire chain competition: connected as 1→2→7→1. Arrows indicate regimes in which cross-inhibition is absent (1) and present (2)
