Abstract
Decisions that favor one’s own interest versus the interest of another individual depend on context and the relationships between individuals. The neurobiology underlying selfish choices or choices that benefit others is not understood. We developed a two-choice social decision-making task in which mice can decide whether to share a reward with their conspecifics. Preference for altruistic choices was modulated by familiarity, sex, social contact, hunger, hierarchical status and emotional state matching. Fiber photometry recordings and chemogenetic manipulations demonstrated that basolateral amygdala (BLA) neurons are involved in the establishment of prosocial decisions. In particular, BLA neurons projecting to the prelimbic (PL) region of the prefrontal cortex mediated the development of a preference for altruistic choices, whereas PL projections to the BLA modulated self-interest motives for decision-making. This provides a neurobiological model of altruistic and selfish choices with relevance to pathologies associated with dysfunctions in social decision-making.

Extended Data Fig. 3 Mice change their responses to share food rewards with their conspecifics.
a, Experimental design of the SDM. Actor mice were trained on a two-choice decision paradigm where nose pokes resulted in food rewards. In the condition i. ‘with recipient’ (orange) one nose poke resulted in food reward to actor (selfish choice) and the other nose poke in food reward both to the actor and to the recipient, in the adjacent compartment (altruistic choice). After an inter-trial interval of 5 seconds (ITI), a new trial started, and actor could make their choice. The location of the two responses were counterbalanced between left and right nose-pokes. In the condition ii. ‘no recipient’ (grey) the structure of the task was identical, but the adjacent compartment was empty. iii. In the condition ‘with toy’, the recipient was replaced. b, Nose poke responses (in percentage) during baseline training in the right and left nose poke holes were not different at the group level (two-tailed paired t-test: t = 0.47, d.f.=24, p = 0.6423, n = 13 mice). c, Change of preference (in percentage) to altruistic responses during the SDM with recipient compared to the baseline (one-sample t-test, t = 2.36, d.f.=64, p = 0.0211, n = 13 mice). d, Number of tested mice grouped by preference. e, Change of preference (in percentage) to altruistic responses during the last session of SDM in males (n = 7) compared to females (n = 6) mice (two-tailed paired t-test: t = 1.94, d.f.=11, p = 0.0773). f, Change of preference when animals were tested one additional day with their recipient (R→R, n = 7) or with an inanimate object (toy, R→T, n = 6) (two-tailed unpaired t-test, t = 2.49, d.f.=11, p = 0.0296). *p < 0.05.

a, Latency to respond (in sec) grouped by altruistic and selfish choices in control (light and dark orange, n = 7) and hM4D mice (light and dark fuchsia, n = 7) during the five days of SDM task (two-way ANOVA, group (control, hM4D, altruistic, selfish), x time (days 1-5), F(12, 96)=2.39, p = 0.0093). b, Number of altruistic choices over 40 minutes of testing during the five days of the SDM in control and hM4D mice (mixed model analysis for each day of testing, day1: (control, hM4D) x time (min), F(16, 132)=0.48, p = 0.9915; day 2: group F(42, 267)=0.42, p = 0.9994; day 3: F(73, 685)=2.85, p < 0.0001; day 4: F(80, 716)=2.13, p < 0.0001; day 5: F(77, 696)=0.85, p = 0.8057). c, Decision preference score in the five days of SDM and following one additional week of testing (day 13) in control (n = 7) and hM4D (n = 7) mice (two-way RM ANOVA, group (control, hM4D) x time (days), F(5, 60)=2.875, p = 0.0416). d, Number of altruistic and selfish choices on test day 13 of the SDM in control (n = 7) and hM4D (n = 7) mice (two-way RM ANOVA, group (control, hM4D) x choice (altruistic, selfish), F(1, 12)=9.661, p = 0.0091). *p < 0.05, **p < 0.01, ***p < 0.001. Values are expressed as mean ± s.e.m.
