Summary of neuron-by neuron analysis during conjunction search. A, Distribution of the number of trials needed to reach the near-perfect performance criterion (95% target choice) when the quality of neural selection reached an asymptote. B, Distribution of the time at which neurons began to discriminate the target from distractors at the near-perfect criterion level. In both plots, gray bars represent data from conjunction search with four stimuli, and black bars represent data from conjunction search with six stimuli. The arrowheads under the abscissa mark the average of each distribution.
