Elimination effect in an eight-choice task with 6.4% coherence. Color-coded spatiotemporal firing pattern of pyramidal cells at Jopp = 1.06 (A) or Jopp = 1.00 (B). Yellow arrows indicate the elimination time for the seven distracting choices. An option is considered to be removed from the choice set when the firing rate of neurons around the direction of this target falls below one-third of the maximum firing rate at the same time. C, The mean time required to eliminate one option relative to the stimulus onset, averaged over 500 correct trials, versus its angular distance from the correct target for different values of Jopp. Jsim is kept at 1.1 in all panels.
