Quenching effect in the dorsal pulvinar and relation to hand movement. (A) Mean percent change in Fano factor from 300 ms pre to 300 ms post target stimulus intervals in area V4, the ventral and dorsal pulvinar and the LGN (V4 N = 100, vPul N = 118, dPul N = 136; LGN N = 105). Error bars indicate +/− 1 SEM. One-sample t-tests, ****p < 0.0001, ***p < 0.001. Upon target presentation, the animal was instructed to pull a lever. (B) Mean percent change in Fano factor from 300 ms pre to 300 ms post RDM stimulus intervals in area V4, the ventral and dorsal pulvinar and the LGN. Error bars indicate +/− 1 SEM. One-sample t-tests, ****p < 0.0001. The RDM stimulus was not followed by a hand movement. (C) Fano factors for the 300 ms post stimulus interval for the target and the RDM stimulus. Pearson’s correlation coefficients. (D) Fano factor time courses of data triggered to the time of the lever pull following the presentation of the target stimulus.
