Timescales of Multineuronal Activity Patterns Reflect Temporal Structure of Visual Stimuli
(A) Trajectory analysis on drifting grating stimuli. Top inset: Average distance from trajectories on test trials of a given stimulus to the model trajectory of the true stimulus (orange) and the model trajectories of other stimuli (magenta). τ = 20 ms. Cohen's d between the two distance traces for different integration time constants, τ, for grating stimuli (bottom inset in (A)), slow (B) and fast (C) segments of natural movies, and a flashed letter sequence (D). Light gray bands indicate stimulus presentation periods. Error bars on distance traces in (A) are s.e.m.
