The differential activity between target in the response field (toRF) choices and target opposite the RF (awayRF) choices to the RF (Δ) is modulated by confidence. A: spike density functions (σ = 10 ms) for the average of 253 single and multiple neurons. Iconography shows the different trial types: solid black lines show the correct trials to the RF in opt-out (OO)-waived trials, solid gray line indicates correct trials away from RF in OO-waived trials, dashed gray line indicates correct trials to the RF when the OO was unavailable, dashed gray line indicates correct trials away from RF when the OO was unavailable. The filled gray bars on the abscissas in A indicate the interval of discharge that was quantified. B, D, and F: bar graphs of the differential (Δ) discharge rate of the neurons shown in A during the cue epoch of visuomotor (B), burst (D), and buildup neuros (F). ΔDischarge rate = discharge rate for correct trials to the RF − discharge rate for correct trials away from the RF in OO-waived and OO-unavailable trials, C, E, and G: Δdischarge rate in the presaccade epoch for visuomotor (C), burst (E), and buildup neurons (G). *P < 0.05, for E, F, and G. H–K: the same layout as shown in A for the single and multiple neurons shown separately for each monkey. MUA, multiunit activity; SU, single-unit activity.
