Timescales of Multineuronal Activity Patterns Reflect Temporal Structure of Visual Stimuli

Figure 1

From spikes to multineuronal patterns.

(A) Low-pass filtering of simultaneously recorded spike trains by convolution with a decaying exponential function. Activity vectors are obtained by sampling the resulting continuous traces at each time step. (B) Color representation of stereotypical patterns corresponding to activity vectors from a dataset recorded with drifting sinusoidal gratings. Color sequences corresponding to trials evoked by 4 grating stimuli are shown, grouped by the stimulus (τ = 20 ms).
