Relationship of average normalized firing rates to behavior. A) Average normalized response on trials with correct detections (“hit”). For each neuron, responses were aligned the onset of motion coherence and then trials with different directions were averaged separately and normalized to the overall peak response during a 1 s period centered on motion coherence onset. There was a prominent, direction selective response shortly after the onset of motion coherence. B) Corresponding data for trials on “miss” trials, using the same scale as in 2A. C) Difference between the average responses on “hit” and “miss” trials, normalized for each neuron to the overall peak response. D) Average normalized response on trials with correct detections. Data and analysis as in 2A, but after aligning trials on the animal’s response. E) Average normalized response on “false alarm” trials, using the same scale as in 2D. F) Average normalized responses to periods without coherent motion that the animal did not respond to (“correct reject”). Epochs were drawn from correctly completed trials using times before the onset of coherent motion that had exactly the same distribution as the trials in 2E. Same scale as in 2D, E.
