6 c , the gain due to C n is only marginally significant: p = 0.036 for both animals and p = 0.121, p = 0.096 for Monkeys 1 and 2, respectively, Wilcoxon signed rank tests, and nonsignificant for paired t tests.) In contrast, prediction performance is not significantly increased when including the preceding spike count ( S n -1 ) after choice history and the current spike count ( Fig. 6 b ).
