Extended Data Fig. 4: Mice are willing to take altruistic decisions under costly situations.
From: Reciprocal cortico-amygdala connections regulate prosocial and selfish choices in mice
Altruistic responses (orange) reinforced on FR2, FR4 and FR6 and selfish responses (blue) reinforced on FR1 expressed as percentage of the total in males (light blue, (n = 7) and females (red, n = 4) mice and responses on the preferred nose poke (NP1, dark grey) reinforced on FR2, FR4 and FR6 and responses on the non-preferred nose poke (NP2, light grey) reinforced on FR1 in mice tested without recipient (n = 6) (FR2: two-way RM ANOVA, group (with recipient males, with recipient females, no recipient) x response (FR1, FR2), F(2, 13)=3.5, p = 0.05. FR4: two-way RM ANOVA, group (with recipient males, with recipient females, no recipient) x response (FR1, FR2), F(2, 13)=5.1, p = 0.0192; FR6. two-way RM ANOVA, group (with recipient males, with recipient females, no recipient) x response (FR1, FR2), F(2, 13)=6.6, p = 0.0103. FR8: two-tailed unpaired t-test, t = 8.32, d.f.=6, p = 0.0002). *p < 0.05, **p < 0.01, ***p < 0.005 n.s., not significant. Values are expressed as mean ± s.e.m.
