The collective behavior of animal groups emerges from the interactions among individuals. These social produce coordinated movements bird flocks and fish schools, but little is known about their developmental emergence neurobiological foundations. By characterizing visually based schooling micro glassfish Danionella cerebrum, we found that development progresses sequentially, with animals first acquiring ability to aggregate, followed by postural alignment partners. This maturation was accompanied neural populations in midbrain were preferentially driven visual stimuli resemble shape fish. Furthermore, isolation over course impaired both encoding motion adults. work demonstrates selective for form conspecifics emerge experience-dependent movement.

ABSTRACT Humans and animals have a remarkable capacity to collectively coordinate their behavior respond environmental challenges. However, the underlying neurobiology remains poorly understood. Here, we found that groups of mice self-organize into huddles at cold ambient temperature during thermal challenge assay. We make active (self-initiated) passive (partner-initiated) decisions enter or exit huddle. Using microendoscopic calcium imaging, are encoded distinctly within dorsomedial prefrontal cortex (dmPFC). Silencing dmPFC activity in some reduced decision-making, but also induced compensatory increase by non-manipulated partners, conserving group’s overall huddle time. These findings reveal how collective is implemented neurobiological mechanisms meet homeostatic needs
