Population activity depends on the value of the entire choice set. Normalized population LIP responses decrease as a function of total value (Vtot). Filled circles represent mean ± SEM LIP activity in the 0–1000 ms after peripheral target onset in the MED-RF condition (Vin = 130 μl) three-target task, for conditions with (red) and without (blue) a target present in the RF. Open symbols represent data from the HIGH-RF condition (Vin = 260 μl; squares) and LOW-RF condition (Vin = 65 μl; inverted triangles, condition 1; triangles, condition 2) experiments; blue symbols indicate RF target-absent conditions.
