Activity of serotonin neurons during reward wait error and reward choice error in the extended reward delay test.
A
, Population activity aligned to the onset of the reward presentation (red, food; blue, water) and to the reward wait error (pink, food wait error; cyan, water wait error) (left, food site, n = 26; right, water site, n = 24). Gray shadings represent SEM. Light yellow areas indicate the periods that were used to analyze average firing rate.
B
, Average firing rate during the first and last 2 s of the waiting period after entry into the reward site in a case of successful entry (red, food; blue, water) and in the case of wait error entry (pink, food wait error; cyan, water wait error) (left, food site, n = 26; right, water site, n = 24; ± SEM).
C
, Population activity aligned to reward site success entry (red, food; blue, water) and to reward choice error entry (orange, water choice error; green, food choice error) (left, food site, n = 43; right, water site, n = 23).
D
, Average firing rate during 2 s after reward site entry in a case of successful entry (red, food; blue, water) and in a case of choice error entry (orange, water choice error; green, food choice error) (left, food site, n = 43; right, water site, n = 23; ±SEM). **p < 0.001, ***p < 0.0001, Wilcoxon's signed-rank test. n.s., Not significant.
