From: The Roles of Serotonin in Decision-making under Social Group Conditions
Decision-making under conflict in social obedience-like behavior and the effects of SSRI. (a) A graph showing 3 representative groups of trial-by-trial competition for the first 50 trials with low (top), moderate (middle), and high (bottom) frequencies of agonistic interactions between subjects during the competition. Subjects in each group are denoted as A-D, and parentheses indicate the ranks of the subjects based on the number of obtaining the rewards. Red and black circles indicate the trials with and without agonist interactions. The animals that exhibited agonist interactions were connected with red lines, and the ones that obtained the rewards were indicated with red circles. (b) A graph showing FAP of mice in each group (dashed lines), and the averages of all groups (circles), ranked from 1st to 4th, based on the number of first food reward access over other mice. Error bars indicate s.e.m. (c) A graph showing a correlation between DS and FAP. (d) A graph, along with illustration of individual cases, showing the number of food accesses (expressed as percentage of trials) of test subjects with SAL and SSRI administration over higher- and lower-FAP opponents. *1p < 0.001. (e) A graph showing a correlation between the number of food accesses against lower- vs. higher-FAP opponents. (f) A graph showing spontaneous locomotion of test subjects when they were placed with higher- or lower-FAPopponents, but without food reward presentation, in the open field chamber.
